2SK1896 N-Channel Silicon MOSFET Datasheet Summary

1. General Overview

The 2SK1896 is an N-channel silicon MOSFET manufactured by SANYO Semiconductors, specifically designed for high-performance applications such as DC-DC converters and motor drives. Key features include ultra-low on-resistance, ultrahigh-speed switching capabilities, low-voltage drive requirements, and a micaless TO-220ML package that facilitates easy mounting. With a maximum drain-to-source voltage of 60V and a continuous drain current of 15A, this device balances power handling and efficiency, making it suitable for battery-powered equipment, industrial control systems, and automotive auxiliary circuits. The datasheet information is based on specifications as of June 1999, with ordering number EN4647.

3. Package & Mechanical Details

3.1 Package Type

• Package: TO-220ML (micaless, easy-mount design)
• Pin Configuration (Top View):
• Exposed Pad: Not specified (standard TO-220ML typically includes a drain-connected heatsink pad for thermal management)

3.2 Package Dimensions (Unit: mm)

• Key dimensions conform to TO-220ML standard specifications (detailed in datasheet drawing 2063A):

4. Functional Features

4.1 Core Performance Advantages

• Low On-Resistance: As low as 0.057Ω (typ) at VGS = 10V, minimizing conduction losses and improving power efficiency.
• Ultrahigh-Speed Switching: Fast turn-on (14ns) and fall (120ns) times enable high-frequency operation in DC-DC converters (ideal for >1MHz switching frequencies).
• Low-Voltage Drive: Threshold voltage of 1.0-2.0V allows compatibility with low-voltage control circuits (e.g., 3.3V or 5V microcontroller outputs).
• High Current Handling: 15A continuous drain current and 60A pulsed current support high-power loads such as small motors and power supplies.

4.2 Thermal Performance

• The TO-220ML package provides a thermal resistance (θJA) suitable for natural convection cooling; derating of power dissipation is required for ambient temperatures above 25°C (refer to PD-Ta characteristic curve in datasheet).
• Maximum channel temperature of 150°C ensures robustness in high-temperature environments (e.g., industrial enclosures).

5. Application Information

5.1 Target Applications

• Motor drive circuits (brushed DC motors)
• Power management modules
• Industrial control systems
• Automotive auxiliary electronics (non-critical systems)

5.2 Test Circuits & Characteristics

• Switching Time Test Circuit: VDD = 30V, RLoad = 3.33Ω, VGS = 3.5V (detailed in datasheet Figure 1)
• Key Characteristic Curves:

5.3 Recommended Operating Conditions

• Gate Drive Voltage: 4V-10V (optimal for minimizing RDS(on))
• Operating Temperature Range: -40°C to +125°C (derated current above 25°C)
• Drain-Source Voltage: ≤50V (for margin below 60V maximum rating)

6. Ordering & Compliance

• Ordering Number: EN4647
• Part Number: 2SK1896
• Manufacturer: SANYO Semiconductors
• Compliance Notes:

7. Safety & Reliability

• Absolute Maximum Ratings: Exceeding these values (even momentarily) may cause permanent device damage or reduced reliability.
• ESD Protection: Standard ESD handling procedures recommended (no specific HBM/CDM ratings provided in datasheet).
• Soldering Recommendations: Follow standard TO-220 soldering practices (e.g., 260°C for 3±0.5 seconds in reflow; 320°C for 3±0.5 seconds for hand soldering) to avoid package/lead damage.
• Mounting: Use appropriate heatsinking for high-power applications (Tc = 25°C rating requires adequate thermal coupling to heatsink).
