Product details
Overview
STTH5R06GY-TR from STMicroelectronics is an AEC-Q101 qualified 5 A, 600 V ultrafast recovery rectifier diode in D²PAK (TO-263) package, optimized for boost-stage PFC in continuous conduction mode and hard-switching DC/DC converters. It delivers 35 ns max reverse recovery time, 1.5 V typical forward voltage at 125 °C, and 2.2 °C/W junction-to-case thermal resistance.
For engineers reviewing the STTH5R06GY-TR datasheet, STTH5R06GY-TR pinout, STTH5R06GY-TR application, or STTH5R06GY-TR equivalent, key selection criteria include ultrafast trr performance under high dIF/dt, low Qrr (110 nC), soft recovery (Sfactor ≥ 0.5), automotive-grade reliability, and thermal management capability in high-power-density automotive and industrial power supplies.
Technical Context
This diode employs a platinum-doped silicon epitaxial structure to achieve controlled carrier lifetime, enabling fast, soft reverse recovery with minimal ringing and EMI generation. Its design targets high-frequency switching topologies where low stored charge and predictable turn-off behavior are critical for efficiency and snubberless operation.
Rated for 175 °C maximum junction temperature and qualified per AEC-Q101, it supports robust operation in automotive under-hood environments. The D²PAK package provides low Rth(j-c) = 2.2 °C/W and enables direct heatsink mounting via the exposed cathode tab, essential for thermally constrained 5–10 kW PFC stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V, suitable for 400 V DC bus systems with safety margin. |
| IF(AV) | 5 A - Average forward current rating at TC = 145 °C, defining continuous conduction capability in boost diodes. |
| trr (max) | 35 ns - Maximum reverse recovery time at IF = 1 A, VR = 30 V, dIF/dt = −50 A/µs; enables >100 kHz switching. |
| Qrr | 110 nC - Reverse recovery charge at Tj = 125 °C, directly impacts turn-off losses and snubber sizing. |
| Sfactor | ≥0.5 - Softness factor ensures gradual minority-carrier removal, reducing voltage overshoot and EMI. |
| Rth(j-c) | 2.2 °C/W - Junction-to-case thermal resistance enables efficient heat transfer to heatsink in D²PAK mounting. |
| VF (typ) | 1.5 V at IF = 5 A, Tj = 125 °C - Low forward drop minimizes conduction loss in high-current PFC applications. |
Pinout & Package
The STTH5R06GY-TR is housed in a surface-mount D²PAK (TO-263) package with an exposed cathode metal tab for thermal and electrical connection. Pin 1 is the anode; the large back-side metal pad is the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead 1) | Forward current entry point | Connected to switch node (e.g., MOSFET drain) in boost topology; must withstand high dv/dt transients. |
| Cathode (exposed tab) | Forward current exit / thermal path | Electrically and thermally connected to output rail and heatsink; requires insulated mounting if output is not ground-referenced. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock per stress test requirements. |
| Ultrafast soft recovery | trr ≤ 35 ns with Sfactor ≥ 0.5 ensures low EMI and reduced voltage spikes during hard commutation. |
| Low thermal resistance | Rth(j-c) = 2.2 °C/W enables >5 W dissipation with <11 °C rise above heatsink, supporting compact thermal design. |
| ECOPACK® compliance | Lead-free, halogen-free packaging meeting RoHS and ELV directives without compromising thermal or electrical performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06D-TR | Lower IF(AV) = 4.5 A; identical VRRM, trr, and package; optimized for lower-cost consumer PSUs. | Not AEC-Q101 qualified; unsuitable for automotive temperature or reliability requirements. | Select when automotive qualification is unnecessary and cost sensitivity outweighs 0.5 A current margin. |
| IXYS MUR560E | Same VRRM and IF(AV); trr = 40 ns (max); Rth(j-c) = 3.0 °C/W; TO-220AC package. | Through-hole mounting only; higher thermal resistance limits power density in compact designs. | Choose for legacy through-hole layouts or where heatsink interface differs significantly from D²PAK footprint. |
Compared with STTH5L06D-TR and MUR560E, the STTH5R06GY-TR uniquely combines AEC-Q101 qualification, D²PAK thermal performance (2.2 °C/W), and soft ultrafast recovery (≤35 ns, Sfactor ≥0.5), making it the only option validated for high-reliability automotive PFC and thermally aggressive industrial applications.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The STTH5R06GY-TR has a rated maximum junction temperature of 175 °C, verified per AEC-Q101 stress testing. Continuous operation at this temperature requires maintaining case temperature ≤145 °C using the D²PAK's 2.2 °C/W Rth(j-c) path and adequate heatsinking-typically achieved with ≥25 cm² copper area and thermal interface material.
Is the cathode tab electrically isolated from the PCB in D²PAK mounting?
No-the cathode tab is the primary electrical and thermal terminal and must be soldered directly to a copper pour or heatsink. If the cathode connects to a non-ground-referenced net (e.g., positive DC bus), electrical isolation requires a dielectric thermal pad or ceramic insulator between tab and heatsink, adding ~0.5–1.0 °C/W to total thermal resistance.
How does soft recovery (Sfactor ≥ 0.5) improve system-level EMI performance?
A soft recovery characteristic ensures minority carriers recombine gradually during turn-off, suppressing high di/dt-induced voltage spikes and oscillatory ringing. Measured data shows peak reverse recovery current (IRM) remains ≤4.5 A under harsh conditions (dIF/dt = −200 A/µs), directly reducing broadband conducted EMI and easing filter design compared to abrupt-recovery diodes.
Can STTH5R06GY-TR replace STTH5R06Y in existing designs?
Yes-STTH5R06GY-TR is the tape-and-reel packaged version of STTH5R06Y, sharing identical electrical, thermal, and mechanical specifications. The "G" denotes green (halogen-free) construction and "Y" indicates D²PAK packaging; both use the same die and qualify to AEC-Q101. No layout or thermal redesign is required for migration.
