STMicroelectronics STTH60L06CW

Overview

STTH60L06CW from STMicroelectronics is an ultrafast high-voltage dual common-cathode rectifier diode in TO-247 package, rated for 600 V repetitive peak reverse voltage, 60 A average forward current (per device), and 175 °C maximum junction temperature. It delivers 1.0 V typical forward voltage at 150 °C and 65 ns maximum reverse recovery time, optimized for discontinuous-mode PFC boost stages and switching power supply output rectification.

For engineers reviewing the STTH60L06CW datasheet, STTH60L06CW pinout, STTH60L06CW application, or STTH60L06CW equivalent, key selection criteria include conduction loss modeling (P = 0.95×IF(AV) + 0.010×IF²(RMS)), thermal resistance (Rth(j–c) = 0.68 °C/W total), soft recovery behavior, and dual-diode coupling effects in shared heatsink layouts.

Technical Context

This dual-diode rectifier uses ST's Turbo 2 600 V technology to achieve ultrafast switching with low Qrr and soft recovery characteristics. Its two independent anodes (A1, A2) share a common cathode (K), enabling interleaved or parallel operation while maintaining low trr (≤65 ns) and low IRM (≤16 A) under dIF/dt up to 500 A/µs at 125 °C junction temperature.

The device features low thermal resistance (Rth(j–c) = 0.68 °C/W total) due to optimized die attachment and TO-247 copper tab construction, supporting high-power density designs. Conduction losses are characterized across IF(AV) = 30–60 A and Tj = 25–150 °C, with VF ranging from 1.55 V (25 °C, 30 A) to 1.24 V (150 °C, 60 A).

FAQ

What is the maximum allowable case temperature for continuous 60 A operation?

The device supports 60 A average forward current at Tc = 110 °C per diode (Table 3). With Rth(j–c) = 0.68 °C/W total and Tj(max) = 175 °C, the maximum sustainable case temperature is 134 °C - however, derating to Tc ≤ 110 °C ensures reliability margin and accounts for thermal coupling between A1 and A2 under simultaneous conduction.

Can STTH60L06CW be used in synchronous rectification topologies?

No - STTH60L06CW is a unidirectional silicon PN junction rectifier with no gate control or body diode functionality. It lacks the MOSFET channel required for synchronous rectification and is not rated for reverse conduction or bidirectional switching. Its role is strictly as a high-speed freewheeling or output rectifier in hard-switched topologies.

How does the dual-anode configuration affect PCB layout and thermal management?

The A1 and A2 pins require separate high-current traces routed to distinct AC inputs or phases, while the common cathode (K) must connect to a low-inductance, wide copper pour feeding the output capacitor bank. Thermal coupling between diodes necessitates symmetric heatsink contact and avoids localized hot spots - measured ∆Tj between diodes is ≤3 °C under balanced 30 A per anode loading.

Is the TO-247 package lead-free and RoHS-compliant?

Yes - STTH60L06CW is manufactured in accordance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The TO-247 package uses lead-free matte tin plating on leads and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), with no special handling required prior to soldering.
