Product details
Overview
STTH15RQ06G2Y-TR from STMicroelectronics is an AEC-Q101 qualified ultrafast high-voltage rectifier diode in D²PAK HV package, rated for 600 V repetitive peak reverse voltage and 15 A average forward current, with 25 ns maximum reverse recovery time and 1.45 V max forward voltage at 150 °C - deployed in LLC full-bridge secondary rectification, PFC stages, and automotive charging systems.
For engineers reviewing the STTH15RQ06G2Y-TR datasheet, STTH15RQ06G2Y-TR pinout, STTH15RQ06G2Y-TR application, or STTH15RQ06G2Y-TR equivalent, this page delivers verified thermal resistance (1.5 °C/W junction-to-case), soft-recovery behavior, creepage distance (5.38 mm anode-to-cathode), and AEC-Q101 qualification status - critical for high-reliability industrial and automotive power designs.
Technical Context
This device implements a planar epitaxial ultrafast silicon rectifier structure optimized for high-frequency switching topologies including LLC resonant converters and active clamp forward circuits. Its soft reverse recovery (S-factor >1.0) minimizes EMI and voltage overshoot during turn-off under high dIF/dt conditions up to 500 A/µs.
Designed for operation across -40 °C to +175 °C junction temperature range, it maintains guaranteed VRRM stability and low IR leakage (≤400 µA at 150 °C), enabling robust performance in thermally constrained environments such as on-board chargers and industrial UPS systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports primary-side isolation and secondary rectification in 400–480 VAC input systems with margin for transient overvoltage |
| IF(AV) | 15 A at TC = 115 °C - enables continuous conduction mode operation in high-power PFC and DC-DC outputs without forced air cooling |
| trr (max) | 25 ns at Tj = 25 °C - reduces switching losses and EMI generation in >100 kHz LLC and phase-shifted full-bridge converters |
| VF (max) | 1.45 V at IF = 15 A, Tj = 150 °C - lowers conduction loss to ≤21.75 W under worst-case thermal conditions |
| Rth(j-c) | 1.5 °C/W - allows direct heatsink mounting with minimal thermal interface resistance for compact thermal design |
| CdA-K | 5.38 mm (min., with top coating) - meets IEC 60664-1 reinforced insulation requirements for 600 V working voltage in EV charging stations |
| Tj range | -40 °C to +175 °C - supports under-hood automotive applications and industrial environments without derating below -40 °C |
Pinout & Package
D²PAK HV package: surface-mount, isolated tab (anode), 3-pin outline with extended creepage; optimized for high-voltage isolation and thermal conduction via copper pad under tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | High-side current entry point | Electrically isolated metal tab serves as anode and primary thermal path - requires insulated mounting to chassis or heatsink |
| Cathode (Pin 1) | Low-side current exit | Standard cathode connection; routed to ground-referenced output rail or snubber network in freewheeling/clamping roles |
| NC (Pin 2) | No connect | Unused terminal - must remain unconnected per datasheet; no internal bonding or electrical function |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for OBC and DC fast-charging modules |
| Soft recovery behavior | S-factor >1.0 across 125–175 °C ensures low di/dt-induced voltage spikes and reduced snubber stress in high-frequency converters |
| D²PAK HV creepage | 5.38 mm (anode-to-cathode, with top coating) satisfies reinforced insulation for 600 V working voltage per IEC 60664-1 |
| Low Rth(j-c) | 1.5 °C/W enables ≥20 W dissipation with ≤30 °C rise above heatsink - eliminates need for oversized thermal pads in space-constrained layouts |
| Wide Tj range | Operates continuously from -40 °C to +175 °C without parameter drift - avoids thermal shutdown in engine-bay-mounted power stages |
Applications
| LLC Resonant Converter Secondary Rectification | Automotive On-Board Charger (OBC) |
|---|---|
Use Scenario: High-efficiency 6.6 kW bidirectional OBC using asymmetric LLC topology with synchronous rectification disabled. IC Role / Device Role / Timing Role: Ultrafast freewheeling diode in secondary-side center-tapped rectifier, handling 15 A DC output with 25 ns trr to minimize dead-time losses. Use Value: Enables >96% peak efficiency at 200 kHz switching frequency while maintaining <100 mV output ripple due to low QRR (250 nC) and soft recovery. |
Use Scenario: 11 kW AC/DC stage in vehicle-integrated charger operating in harsh ambient (105 °C under hood). IC Role / Device Role / Timing Role: High-voltage output rectifier in dual-phase interleaved PFC front-end, conducting 15 A average current at 175 °C junction temperature. Use Value: Guarantees VRRM stability and IR leakage ≤400 µA at 150 °C - prevents thermal runaway during sustained high-load operation. |
| Industrial Uninterruptible Power Supply (UPS) | EV DC Fast-Charging Station Power Stage |
Use Scenario: Online double-conversion UPS with 48 V battery backup and 380 VDC bus, requiring zero-crossing-free rectification. IC Role / Device Role / Timing Role: Clamping diode across IGBTs in inverter bridge, absorbing inductive energy during turn-off with 120 A surge rating. Use Value: Withstands 120 A non-repetitive surge (tp = 10 ms) and exhibits <70 ns trr under high dIF/dt - suppresses voltage overshoot below 650 V. |
Use Scenario: 150 kW modular charging cabinet with SiC MOSFET-based totem-pole PFC and isolated DC/DC stages. IC Role / Device Role / Timing Role: Secondary-side rectifier in 1000 VDC output stage, mounted directly to liquid-cooled cold plate via isolated D²PAK HV tab. Use Value: 5.38 mm creepage distance and ECOPACK®2 compliance ensure long-term insulation integrity in humid outdoor environments per IEC 62477-1. |
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 |
|---|---|---|---|
| STTH15R06DJ-TR | D²PAK (non-HV) package; 3.48 mm creepage (no top coating); same VRRM/IF(AV)/trr specs | Lacks reinforced insulation for 600 V working voltage - unsuitable for outdoor EVSE or medical-grade UPS | Select only where creepage <4 mm is acceptable and cost sensitivity outweighs safety certification needs |
| IXYS MUR1560CT | TO-220AB dual-diode configuration; 600 V VRRM; 35 ns trr (typ.); higher VF (1.7 V @ 15 A) | Requires external heatsink and mounting hardware; not AEC-Q101 qualified | Prefer for legacy industrial SMPS where dual-cathode layout simplifies PCB routing but automotive qualification is unnecessary |
Compared with STTH15R06DJ-TR, STTH15RQ06G2Y-TR provides certified reinforced insulation for high-voltage safety compliance; versus IXYS MUR1560CT, it offers lower trr, AEC-Q101 validation, and surface-mount integration - making it optimal for next-gen automotive and grid-edge power electronics.

FAQ
Is STTH15RQ06G2Y-TR pin-compatible with STTH15RQ06GY-TR?
No - STTH15RQ06G2Y-TR uses the D²PAK HV package with extended creepage and a no-connect (NC) pin, whereas STTH15RQ06GY-TR uses standard D²PAK with two functional pins and no NC terminal. PCB footprints and thermal pad layouts differ; mechanical redesign is required for substitution.
What is the maximum allowable case temperature for continuous 15 A operation?
The datasheet specifies IF(AV) = 15 A at TC = 115 °C. Exceeding 115 °C case temperature requires linear derating: at TC = 130 °C, maximum IF(AV) drops to ~12.2 A; at TC = 145 °C, it falls to ~9.5 A - verified by Figure 1 and thermal impedance curves in DS12163 Rev 2.
Does the "Q" in STTH15RQ06G2Y-TR indicate a specific qualification level?
Yes - the "Q" denotes AEC-Q101 qualification per the ST product naming convention. This part has passed stress tests including HTGB, HTRB, temperature cycling, and ESD (HBM ≥2 kV), confirming suitability for automotive powertrain and charging applications per ISO/TS 16949 requirements.
Can STTH15RQ06G2Y-TR be used in place of a Schottky diode in 600 V applications?
No - Schottky diodes are limited to ~200 V VRRM due to inherent barrier height constraints. STTH15RQ06G2Y-TR is a PN-junction ultrafast rectifier optimized for 600 V operation; substituting a Schottky would cause catastrophic breakdown. Its 25 ns trr and soft recovery provide comparable switching performance to SiC Schottkys in this voltage class.
