STMicroelectronics STP11NM60A

Overview

STP11NM60A from STMicroelectronics is an N-channel 600 V, 11 A, 0.4 Ω R_DS(on) MDmesh™ Power MOSFET in TO-220 package, designed for high-voltage switching in offline SMPS, PFC stages, and industrial motor drives where high dv/dt immunity and low gate charge are critical.

For engineers reviewing the STP11NM60A datasheet, STP11NM60A pinout, STP11NM60A application, or STP11NM60A equivalent, key selection factors include its 600 V breakdown voltage, 0.4 Ω typ. on-resistance at V_GS = 10 V, 35 nC total gate charge, 15 V/ns dv/dt rating, and TO-220 thermal resistance of 1.13 °C/W.

Technical Context

This MOSFET employs ST's MDmesh™ technology-combining Multiple Drain process with PowerMESH™ horizontal layout-to achieve ultra-low R_DS(on) while maintaining robust 600 V blocking capability and high dv/dt tolerance (15 V/ns). Its internal body diode exhibits 560 ns reverse recovery time and 5.7 µC Q_rr under 11 A, 100 V, 150 °C conditions.

The device operates with gate threshold voltage of 2–4 V, forward transconductance of 10 S, and features low input capacitance (1211 pF C_iss) and gate input resistance of 1.9 Ω, enabling fast, efficient switching in hard-switched converters up to several hundred kHz.

Key Specifications

Pinout & Package

STP11NM60A uses a standard TO-220 package with 3-pin configuration: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source. The metal tab is electrically connected to the Drain terminal and must be isolated from heatsink unless circuit topology permits common-drain mounting.

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The STP11NM60A supports 7 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-220 package and ensures safe operation within the Safe Operating Area (SOA) curve at elevated temperatures.

Does STP11NM60A have integrated gate protection?

No, STP11NM60A does not include integrated gate Zener protection. Its gate-source voltage rating is ±30 V, and external gate clamping (e.g., 18 V TVS) is recommended in noisy environments or when using high-impedance gate drivers to prevent overvoltage damage.

Can STP11NM60A replace STP12NK60Z in existing designs?

Yes, STP11NM60A can replace STP12NK60Z in most cases due to identical pinout, voltage rating, and package. However, STP11NM60A has lower R_DS(on) (0.4 Ω vs. 0.58 Ω) and no built-in gate Zener, so gate drive design and thermal layout may require verification for optimal performance.

What is the typical reverse recovery charge of the body diode?

The typical reverse recovery charge (Q_rr) of the intrinsic body diode is 5.7 µC, measured at I_SD = 11 A, di/dt = 100 A/µs, V_DD = 100 V, and T_j = 150 °C. This value directly impacts switching loss and EMI in half-bridge and synchronous rectifier configurations.
