STMicroelectronics STB36N60M6

Overview

STB36N60M6 from STMicroelectronics is an N-channel 600 V, 30 A MDmesh™ M6 Power MOSFET in D²PAK (TO-263) package, featuring 99 mΩ max R_DS(on), 100% avalanche tested, and Zener-protected for robust switching in high-voltage SMPS, PFC, and industrial inverters.

For engineers reviewing the STB36N60M6 datasheet, STB36N60M6 pinout, STB36N60M6 application, or STB36N60M6 equivalent, key selection criteria include its 50 V/ns MOSFET dv/dt ruggedness, 750 mJ single-pulse avalanche energy, 44.3 nC total gate charge, and thermal resistance of 0.6 °C/W junction-to-case.

Technical Context

This device implements ST's MDmesh™ M6 superjunction technology to simultaneously reduce conduction loss (85–99 mΩ typ./max at V_GS = 10 V, I_D = 15 A) and switching loss via low C_iss (1960 pF), C_oss (93 pF), and C_rss (6 pF), enabling high-frequency operation up to 100 kHz in hard-switched topologies.

Its integrated source-drain diode delivers 30 A continuous/102 A pulsed current with 340 ns reverse recovery time (T_j = 25 °C) and 5.3 μC Q_rr, supporting synchronous rectification and flyback snubberless designs without external diode replacement.

FAQ

What is the maximum recommended gate resistor value for reliable switching?

The datasheet specifies 4.7 Ω for switching time characterization. For 100 kHz operation, a 10–15 Ω gate resistor balances switching loss reduction and Miller-induced oscillation suppression. Values above 22 Ω increase turn-off delay beyond 60 ns and risk incomplete discharge under high di/dt conditions.

Can STB36N60M6 be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) (confirmed in Figure 11) enables current sharing. Layout must ensure matched gate loop inductance (<10 nH difference) and symmetrical thermal coupling; derate total current to 80% of sum of individual ratings to maintain safe SOA margins.

Does the Zener protection cover both positive and negative gate transients?

Yes - the integrated bidirectional Zener clamps gate-source voltage to ±20 V typical, protecting against both positive overvoltage (e.g., Miller spike) and negative transients (e.g., driver undershoot). This eliminates need for external TVS diodes in most 12 V gate drive implementations.

What is the minimum PCB copper area needed for thermal compliance at 19 A continuous?

Per Table 3, R_thj-pcb = 30 °C/W on 1 inch² FR-4 with 2 oz copper. To maintain T_j ≤ 125 °C at 19 A (P_D ≈ 35.7 W), minimum copper area is 2.5 inch² with thermal vias (≥12×0.3 mm) under the drain tab - verified per Figure 21 footprint recommendation.
