Product details

Overview

STTH30L06CW from STMicroelectronics is a 600 V, dual ultrafast high-voltage rectifier in TO-247 package, optimized as a boost diode in discontinuous/critical-mode PFC circuits and freewheeling diode in switch-mode power supplies. It delivers 30 A RMS forward current per device, 55 ns max reverse recovery time, 0.95 V typical forward voltage at 150 °C, and 1.15 °C/W total junction-to-case thermal resistance.

For engineers reviewing the STTH30L06CW datasheet, STTH30L06CW pinout, STTH30L06CW application, or STTH30L06CW equivalent, key selection criteria include reverse recovery softness (S factor >1.0), low conduction loss equation (P = 0.94×IF(AV) + 0.017×IF²(RMS)), junction temperature derating to 175 °C, and ECOPACK®2 compliance for industrial power conversion designs.

Technical Context

This dual-diode rectifier integrates two independent 600 V, 15 A average-per-diode silicon junctions in a single TO-247 thermally enhanced package. Its Turbo 2 technology enables ultrafast switching with soft reverse recovery (S factor >1.0 at 100 A/µs), minimizing EMI and voltage overshoot during turn-off in high-frequency PFC stages.

The device operates with a maximum junction temperature of 175 °C and features low thermal resistance (R_th(j-c) = 1.15 °C/W total), enabling high-power density designs without forced air cooling. Reverse leakage remains ≤400 µA at 150 °C and 600 V, supporting stable operation in high-temperature industrial environments.

Key Specifications

T_j(max)	+175 °C - Enables compact thermal design with extended safe operating area at high ambient

Pinout & Package

STTH30L06CW uses a 3-pin TO-247 package with isolated cathode terminals (K1, K2) and shared anode (A). The metal tab is electrically connected to the anode and serves as primary thermal path to heatsink. Mounting torque must be 0.8 N·m (max 1.0 N·m).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (K1)	Cathode 1	Independent cathode for first diode; enables dual-channel layout in interleaved PFC
Pin 2 (A)	Anode (shared)	Common anode connection; electrically tied to metal tab for low-inductance thermal path
Pin 3 (K2)	Cathode 2	Independent cathode for second diode; supports phase-split or redundant freewheeling paths

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast high-voltage rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH30L06CG	D²PAK package (vs. TO-247); higher R_th(j-c) = 1.7 °C/W per diode; same electrical specs	Better suited for surface-mount PCB assembly with limited heatsink access; lower power density	Select when automated assembly and board space constraints outweigh thermal performance needs
IXYS MUR3060CT	600 V, 30 A dual; t_rr = 65 ns max; V_F = 1.15 V @ 15 A/125 °C; TO-247 package	Higher conduction loss and slower recovery increase switching loss by ~15% in CrCM PFC	Acceptable for cost-sensitive 1–2 kW designs where efficiency >94% suffices and thermal margin is ample

Compared with STTH30L06CG, the STTH30L06CW offers 33% lower thermal resistance and direct bolt-down heatsinking; versus MUR3060CT, it delivers 18% lower conduction loss and 15% faster recovery-critical for high-efficiency, high-power-density PFC and inverter designs.

FAQ

What is the maximum continuous forward current rating for STTH30L06CW at 125 °C case temperature?

At T_C = 125 °C, STTH30L06CW is rated for 30 A average forward current per device (2 × 15 A per diode), as confirmed in Table 2 of the official datasheet (DocID10761 Rev 2, page 2). This rating assumes proper heatsinking and adheres to the specified thermal resistance of 1.15 °C/W total junction-to-case.

Does STTH30L06CW have electrically isolated cathodes?

Yes. STTH30L06CW integrates two fully independent diodes with separate cathode terminals (K1 and K2) and a shared anode (A) connected to the metal tab. This configuration is explicitly shown in the device summary diagram (page 1) and enables true dual-channel operation without internal coupling.

Can STTH30L06CW be used in place of a single-diode TO-247 rectifier?

No-it is a dual-diode device with two independent cathodes and one shared anode. Replacing a single-diode rectifier requires either using only one diode section (with K2 left unconnected) or redesigning the circuit to exploit dual-cathode functionality, such as interleaved PFC or redundant freewheeling paths.

What is the recommended mounting torque for the TO-247 package?

The datasheet specifies a recommended torque value of 0.8 N·m, with a maximum allowable torque of 1.0 N·m (Section 2, Package Information, page 6). Exceeding this risks mechanical damage to the leadframe or die attach, compromising thermal performance and long-term reliability.
