STMicroelectronics STTH30RQ06L2-TR

Overview

STTH30RQ06L2-TR from STMicroelectronics is a 600 V, 30 A ultrafast high-voltage rectifier diode in HU3PAK package, designed for secondary-side rectification in high-efficiency power converters. It delivers typ. 1.45 V forward voltage at 15 A/150 °C, 30 ns max reverse recovery time, and operates up to +175 °C junction temperature-enabling compact, thermally robust DC/DC and EV charging station designs.

For engineers reviewing the STTH30RQ06L2-TR datasheet, STTH30RQ06L2-TR pinout, STTH30RQ06L2-TR application, or STTH30RQ06L2-TR equivalent, key selection criteria include ultrafast trr (≤30 ns), low thermal resistance (Rth(j-c) = 0.7 °C/W), high IF(AV) rating (30 A @ TC = 120 °C), and HU3PAK's surface-mount thermal performance for high-power density layouts.

Technical Context

This device implements ST's proprietary 600 V ultrafast silicon technology optimized for minimal reverse recovery charge (Qrr = 360 nC) and soft recovery behavior (S-factor > 1.0), reducing EMI and switching losses in hard-switched topologies. Its low IR (800 µA max @ 150 °C, VR = 600 V) ensures stable blocking under high-temperature operation.

The HU3PAK package integrates a copper leadframe with exposed thermal pad and optimized internal bond wire layout, enabling direct PCB heat sinking and achieving Rth(j-c) = 0.7 °C/W-critical for maintaining Tj ≤ 175 °C in continuous 30 A conduction without forced airflow.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable case temperature for continuous operation?

The device is rated for IF(AV) = 30 A at TC = 120 °C per datasheet absolute ratings. Operation above this temperature requires derating per Figure 1 (P_F(AV) vs. I_F(AV) curves); sustained TC > 130 °C risks exceeding T_j(max) = 175 °C unless thermal design accounts for R_th(j-c) = 0.7 °C/W and PCB copper area.

Can STTH30RQ06L2-TR replace a standard fast recovery diode in an existing 100 kHz flyback design?

Yes-its 30 ns trr (vs. typical 75–150 ns for standard FRDs) reduces turn-off loss and EMI, allowing direct drop-in replacement if layout accommodates the HU3PAK footprint and thermal pad soldering. Verify peak reverse voltage margin remains ≥20% above circuit V_R due to lower Q_rr-induced voltage spikes.

Is the HU3PAK package lead-free and RoHS-compliant?

Yes-STTH30RQ06L2-TR is manufactured in ST's ECOPACK®2-compliant HU3PAK package, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The epoxy mold compound is UL94 V0 rated, and all terminations use lead-free matte tin plating per JEDEC J-STD-020 moisture sensitivity level 3.

How does the soft recovery characteristic affect EMI filter design?

With S-factor > 1.0 across dI_F/dt = 100–500 A/µs (Figure 8), the diode exhibits gradual current decay rather than abrupt turn-off, reducing high-frequency spectral content above 30 MHz. This permits smaller Y-capacitors and fewer ferrite beads in Class B EMI filters for EV and industrial applications.
