Infineon Technologies SPP20N60S5HKSA1

Overview

SPP20N60S5 from Infineon Technologies is a 600 V, 20 A CoolMOS™ superjunction N-channel power MOSFET in PG-TO220 package, featuring R_DS(on) = 0.19 Ω (T_j = 25°C), ultra-low gate charge (Q_g = 79 nC), and periodic avalanche rating. It serves as a high-efficiency primary-side switch in offline SMPS, PFC stages, and industrial motor drives operating up to 150°C junction temperature.

For engineers reviewing the SPP20N60S5 datasheet, SPP20N60S5 pinout, SPP20N60S5 application, or SPP20N60S5 equivalent, key selection criteria include its 20 V/ns dv/dt immunity, 690 mJ single-pulse avalanche energy, 3000 pF input capacitance, and thermal resistance R_thJC = 0.6 K/W - critical for high-reliability 600 V hard-switched topologies.

Technical Context

This device implements Infineon's 5th-generation CoolMOS™ superjunction architecture, optimized for reduced conduction and switching losses simultaneously. Its low effective output capacitance (C_o(er) = 83 pF) and minimized reverse transfer capacitance (C_rss = 28 pF) enable fast, low-loss turn-off with controlled voltage overshoot in clamped inductive switching.

The integrated body diode exhibits t_rr = 610 ns and Q_rr = 12 µC under V_R = 350 V, I_F = 20 A, and di_F/dt = 100 A/µs - enabling moderate-frequency synchronous rectification or freewheeling in bridge configurations without external diode supplementation.

Key Specifications

Pinout & Package

Package: PG-TO220 (standard through-hole, 3-pin, isolated tab). Pin 1 = Gate, Pin 2 = Drain (tab-connected), Pin 3 = Source. The metal tab is electrically connected to the Drain terminal and must be insulated from heatsink unless circuit topology requires common-drain configuration.

FAQ

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

The SPP20N60S5 supports 13 A continuous drain current at T_C = 100°C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO220 package and must be verified against actual PCB layout, heatsink interface, and ambient conditions using the provided R_thJC = 0.6 K/W and transient thermal impedance curves.

Does this MOSFET require a negative gate voltage for reliable turn-off?

No - the SPP20N60S5 has a gate threshold voltage (V_GS(th)) of 3.5–5.5 V and is fully enhanced at V_GS = 10 V. A gate drive range of 0 V to +10 V is sufficient; applying negative voltage is unnecessary and not recommended per datasheet guidelines.

Can the body diode be used for synchronous rectification in a 100 kHz LLC converter?

Yes - the body diode exhibits t_rr = 610 ns and Q_rr = 12 µC under standard test conditions, enabling usable synchronous rectification up to ~150 kHz when paired with appropriate gate timing control. However, dedicated SR controllers are recommended to manage reverse recovery and prevent shoot-through.

Is the TO220 tab electrically isolated from the leads?

No - the metal tab is internally connected to the Drain (Pin 2) and is not electrically isolated. When mounting to a heatsink, an insulating pad or shoulder washer must be used unless the heatsink is intentionally tied to the high-voltage drain rail. This is confirmed in the "Package Outline" and "Thermal Characteristics" sections of the official datasheet.
