STMicroelectronics STP30N65M5

Overview

STP30N65M5 from STMicroelectronics is an N-channel 650 V, 125 mΩ typ. (139 mΩ max), 22 A Power MOSFET based on MDmesh M5 vertical process technology in TO-220 package. It delivers extremely low R_DS(on), high dv/dt capability (15 V/ns), and 100% avalanche tested ruggedness for high-efficiency switching in offline SMPS, PFC stages, and industrial motor drives.

For engineers reviewing the STP30N65M5 datasheet, STP30N65M5 pinout, STP30N65M5 application, or STP30N65M5 equivalent, key selection criteria include its 650 V V_DSS, 139 mΩ R_DS(on) at 10 V_GS, 88 A pulsed drain current, 140 W power dissipation at T_C = 25 °C, and 500 mJ single-pulse avalanche energy - all critical for reliable high-voltage hard-switching designs.

Technical Context

This device implements ST's MDmesh M5 silicon architecture, combining a vertical superjunction structure with optimized charge balancing to achieve ultra-low conduction loss without sacrificing switching speed. Its gate charge profile (Q_g = 64 nC, Q_gd = 25 nC) supports fast, controllable turn-off with minimal Miller-induced oscillation.

The integrated body diode exhibits 336 ns reverse recovery time (T_J = 25 °C) and 6 µC Q_rr, enabling robust operation in inductive load switching and synchronous rectification topologies where diode recovery stress must be managed.

Key Specifications

Pinout & Package

STP30N65M5 is housed in a TO-220 package with isolated tab (pin 2 = Drain, pin 1 = Gate, pin 3 = Source). The metal tab is electrically connected to the Drain terminal and serves as the primary thermal interface.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power switching applications.

Compared with STW30N65M5, STP30N65M5 offers identical electrical specs but reduced thermal capacity and smaller footprint; compared with IPP65R190CFD7, it trades higher R_DS(on) for guaranteed avalanche ruggedness and superior dv/dt immunity - making it more suitable for cost-sensitive, reliability-critical industrial inverters.

FAQ

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

The STP30N65M5 supports 13 A continuous drain current at T_C = 100 °C, as specified in Table 1 of DS6070 Rev 4. This rating reflects derating from the 22 A value at 25 °C due to thermal resistance limitations and safe operating area constraints at elevated temperatures.

Is the TO-220 package tab electrically isolated?

No - the metal tab of the STP30N65M5 TO-220 package is internally connected to the Drain terminal (Pin 2), as confirmed by the pinout diagram in Figure AM01475v1_noZen and package mechanical data in Table 9. Electrical isolation from heatsink requires insulating hardware or thermal pad.

Does STP30N65M5 have a fully characterized body diode for synchronous rectification?

Yes - the body diode is fully characterized per Table 7: ISD = 22 A continuous, trr = 336 ns (T_J = 25 °C), Q_rr = 6 µC, and V_SD = 1.5 V at 22 A. These parameters are measured and guaranteed, supporting use in quasi-resonant and LLC topologies where diode behavior directly impacts efficiency.

Can STP30N65M5 replace STP20NM60FD in existing designs?

No - STP20NM60FD is a 600 V, 20 A, 250 mΩ Fast Diode MOSFET with different gate charge (Q_g ≈ 45 nC) and diode characteristics. STP30N65M5 has higher V_DSS, lower R_DS(on), and slower diode recovery (336 ns vs ~120 ns), requiring gate drive and layout re-evaluation to avoid overvoltage or shoot-through.
