STMicroelectronics STP25NM60N

Overview

STP25NM60N from STMicroelectronics is an N-channel 600 V, 21 A, 0.130 Ω R_DS(on) MDmesh™ II Power MOSFET in TO-220 package, designed for high-efficiency switching power supplies and PFC stages. It features 100% avalanche tested ruggedness, low gate charge (84 nC), and low input capacitance (2400 pF), enabling fast switching with reduced conduction and switching losses in 50–100 kHz hard-switched SMPS.

For engineers reviewing the STP25NM60N datasheet, STP25NM60N pinout, STP25NM60N application, or STP25NM60N equivalent, key selection criteria include its 600 V V_DSS, 0.130 Ω on-resistance at 10 V_GS, 84 nC total gate charge, 150 °C max junction temperature, and TO-220 thermal resistance of 0.78 °C/W - all critical for industrial AC-DC converters and solar inverters requiring high reliability under repetitive avalanche stress.

Technical Context

This device employs ST's second-generation MDmesh™ vertical structure combined with strip layout to minimize both R_DS(on) and gate charge simultaneously. Its 600 V breakdown voltage is rated at T_j = 150 °C with guaranteed 100% UIS testing up to 10 A and 850 mJ single-pulse avalanche energy.

The MOSFET delivers low diode reverse recovery charge (Q_rr = 7.2 µC at 25 °C) and fast trr (427 ns), supporting ZVS-capable topologies. Gate threshold voltage is tightly specified (2–4 V), and dynamic parameters - including C_iss = 2400 pF, C_oss = 200 pF, and C_rss = 25 pF - are characterized at 50 V and 1 MHz for accurate snubber and driver design.

Key Specifications

Pinout & Package

STP25NM60N uses a standard TO-220 package with three leads: Drain (pin 1), Gate (pin 2), and Source (pin 3). The metal tab is electrically connected to the Drain terminal and must be isolated from heatsink unless circuit topology requires common-drain configuration.

Equivalent & Alternatives

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

Compared with STW25NM60N, STP25NM60N trades thermal performance for lower cost and smaller footprint in TO-220; versus FDPF18N50FT, it provides superior 600 V ruggedness and lower R_DS(on) at the expense of higher Q_g, making it optimal for efficiency-critical 600 V industrial SMPS.

FAQ

Is STP25NM60N suitable for use in continuous conduction mode (CCM) PFC circuits?

Yes. With its 21 A continuous drain current rating at 25 °C case temperature, 0.130 Ω R_DS(on), and low Q_rr (7.2 µC), STP25NM60N supports CCM PFC operation up to 1.2 kW at 100 kHz. Its 150 °C maximum junction temperature and 0.78 °C/W thermal resistance allow stable thermal performance when mounted on a 15 cm² aluminum heatsink with forced airflow.

What is the recommended gate resistor value for STP25NM60N in a 65 kHz half-bridge converter?

A 4.7 Ω non-inductive gate resistor is recommended, based on the device's 84 nC total gate charge and 44 nC gate-drain charge. This value balances switching speed (typical t_f = 24 ns) against EMI and shoot-through risk, as validated in ST's application note AN4107 for 600 V MDmesh™ II devices in hard-switched topologies.

Does STP25NM60N have integrated ESD protection on the gate?

No. STP25NM60N has no integrated gate ESD protection diode. Its gate oxide is rated for ±25 V absolute maximum, and gate-body leakage is specified at 100 nA at ±20 V. External TVS or RC snubber networks are required in production PCB layouts to prevent damage during handling or system-level transients.

Can STP25NM60N replace STP20NM60FD in an existing design?

No - STP20NM60FD is a 600 V FDmesh™ III device with different gate charge profile (Q_g = 65 nC) and lower R_DS(on) (0.195 Ω). Swapping requires re-optimizing gate drive strength and layout parasitics due to STP25NM60N's higher Q_g and different C_iss/C_oss ratio, which affects zero-voltage switching behavior and EMI signature.
