STMicroelectronics STTH200L06TV1

Overview

STTH200L06TV1 from STMicroelectronics is a dual ultrafast high-voltage rectifier diode in ISOTOP package, rated at 600 V repetitive peak reverse voltage, 120 A average forward current per diode at Tc = 35 °C, and 80 ns maximum reverse recovery time. It delivers low conduction loss (VF typ. 0.95 V at 150 °C) and low thermal resistance (Rth(j-c) = 0.60 °C/W per diode), enabling high-efficiency rectification in industrial switch-mode power supplies.

For engineers reviewing the STTH200L06TV1 datasheet, STTH200L06TV1 pinout, STTH200L06TV1 application, or STTH200L06TV1 equivalent, key selection criteria include dual-diode isolation, 2500 VRMS insulation rating, soft reverse recovery behavior (S-factor > 0.8), and compatibility with high-dI/dt freewheeling in PFC and output stages of 3–10 kW converters.

Technical Context

This dual-diode device integrates two independent 600 V, 120 A ultrafast rectifiers in a single insulated ISOTOP housing. Each diode exhibits typ. 0.95 V forward drop at 100 A/150 °C and max. 80 ns trr at 25 °C under standardized test conditions (IF = 0.5 A, Irr = 0.25 A, IR = 1 A).

The ISOTOP package provides 2500 VRMS galvanic isolation between case and terminals, enabling direct heatsink mounting without insulating washers. Thermal coupling between diodes is characterized by Rth(c) = 0.1 °C/W, allowing accurate junction temperature estimation when both diodes operate simultaneously.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable heatsink temperature for continuous 120 A operation per diode?

At 120 A IF(AV) per diode and Tc = 35 °C, the junction-to-case thermal resistance is 0.60 °C/W. With typical conduction loss of 95 W per diode, the maximum allowable heatsink temperature is 85 °C to maintain Tj ≤ 150 °C. Derating is required above this temperature per Figure 1 in the datasheet.

Can STTH200L06TV1 be used in parallel configurations?

No-STTH200L06TV1 contains two independent diodes in one package but is not designed for paralleling multiple units. Its ISOTOP mechanical design and thermal coupling (Rth(c) = 0.1 °C/W) make current sharing unreliable without external balancing resistors and matched thermal paths.

Does the 2500 VRMS isolation rating apply to all terminal-to-case combinations?

Yes-the 2500 VRMS isolation is verified between each of A1, K1, A2, and K2 terminals and the metal baseplate (case). This is confirmed in the ISOTOP package specification section and applies under sinusoidal AC stress per UL/IEC standards.

What is the recommended gate drive layout for minimizing EMI when using STTH200L06TV1 in a PFC boost stage?

Minimize loop area between diode cathodes (K1/K2), boost inductor, and output capacitor. Route high-dI/dt paths over solid ground planes, place snubbers directly across diode terminals, and avoid routing gate traces near K1/K2. The soft recovery (S > 0.8) reduces dV/dt-induced noise, but layout remains critical for <150 MHz EMI compliance.
