Product details
Overview
STTH5R06BY-TR from STMicroelectronics is an AEC-Q101 qualified 5 A, 600 V ultrafast recovery rectifier diode in DPAK package, featuring 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. It serves as a boost diode in continuous-mode PFC circuits and as a freewheeling diode in automotive DC/DC converters and industrial switch-mode power supplies.
For engineers reviewing the STTH5R06BY-TR datasheet, STTH5R06BY-TR pinout, STTH5R06BY-TR application, or STTH5R06BY-TR equivalent, key selection criteria include ultrafast switching performance (trr ≤ 35 ns), low conduction loss (VF = 1.5 V @ 5 A, 125 °C), AEC-Q101 qualification for automotive use, thermal resistance (Rth(j-c) = 2.2 °C/W), and DPAK package compatibility with high-power density PCB layouts.
Technical Context
This diode employs a platinum-doped silicon epitaxial structure to achieve soft, ultrafast reverse recovery with S-factor ≥ 0.5 and Qrr = 110 nC, minimizing EMI and voltage overshoot during hard-switching transitions. Its design targets high-frequency (>100 kHz) operation in continuous-conduction-mode PFC stages and synchronous rectification auxiliary paths.
The device operates across -40 °C to +175 °C junction temperature range, with IR ≤ 300 µA at 125 °C and VR = 600 V, and supports surge currents up to 50 A (tp = 10 ms, sinusoidal) in DPAK configuration-enabling robustness in automotive transients and industrial load dumps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 5 A average forward current at TC = 145 °C - defines continuous conduction capability in PFC boost legs |
| VRRM | 600 V repetitive peak reverse voltage - supports 400 V nominal DC bus with 50 % safety margin |
| trr(max) | 35 ns reverse recovery time at IF = 1 A, dIF/dt = −50 A/µs - enables >300 kHz switching without excessive turn-off loss |
| VF(typ) | 1.5 V forward voltage at IF = 5 A, Tj = 125 °C - determines conduction loss of ~7.5 W at full load |
| Rth(j-c) | 2.2 °C/W junction-to-case thermal resistance - allows 11.4 W power dissipation with 25 °C case temperature rise |
| IRM(max) | 6 A peak reverse recovery current at IF = 5 A - sets snubber sizing and clamp diode stress in flyback/freewheeling topologies |
| Qrr | 110 nC reverse recovery charge - directly impacts turn-off energy loss (E = Qrr × VR) in hard-switched converters |
Pinout & Package
DPAK (TO-252) surface-mount package with isolated tab (cathode-connected), 3-terminal configuration, UL94 V0 epoxy molding compound, and recommended footprint per Figure 17 (DS6874 Rev 2, p.10). Thermal pad requires solder paste stencil opening ≥ 70 % coverage for optimal Rth(j-a) performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry | Connected to switching node (e.g., MOSFET drain in boost); must withstand dV/dt > 500 V/µs |
| Cathode (Pin 2) | Forward current exit / high-side return | Electrically tied to thermal tab; requires low-inductance connection to output capacitor ground |
| Tab / Cathode Pad | Thermal path & cathode terminal | Primary heat extraction path (Rth(j-c) = 2.2 °C/W); must be soldered to ≥ 25 cm² copper area for rated IF(AV) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood applications including engine control units and ADAS power modules |
| Ultrafast soft recovery | S-factor ≥ 0.5 ensures low di/dt-induced voltage ringing and reduced EMI filter burden |
| Low VF at high Tj | 1.5 V @ 125 °C enables stable efficiency in thermally constrained enclosures (e.g., integrated DC/DC modules) |
| Low Rth(j-c) | 2.2 °C/W allows direct mounting to heatsink without thermal interface material in space-constrained designs |
| ECOPACK® compliance | Halogen-free, RoHS-compliant construction meets automotive environmental standards (e.g., ELV Directive) |

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 | D²PAK package, 25 A IF(RMS), Rth(j-c) = 1.5 °C/W, VF = 1.65 V @ 5 A, 125 °C | Better thermal performance but larger footprint; suited for higher-power PFC where board space permits | Select when junction temperature must stay <125 °C under 5 A continuous load without forced air cooling |
| ON Semiconductor MUR560E | DPAK, 600 V, 5 A, trr = 50 ns (max), VF = 1.75 V @ 5 A, 125 °C, no AEC-Q101 qualification | Lacks automotive qualification; higher trr increases turn-off loss by ~40 % in 100 kHz PFC | Acceptable for industrial non-automotive applications where cost sensitivity outweighs EMI and thermal margins |
Compared with STTH5R06BY-TR, STTH5L06D-TR offers superior thermal management but requires D²PAK layout changes, while MUR560E trades AEC-Q101 compliance and ultrafast recovery for lower unit cost-making STTH5R06BY-TR optimal for space-constrained, thermally demanding automotive PFC and DC/DC designs.

FAQ
Is STTH5R06BY-TR pin-compatible with STTH5R06GY-TR?
No. STTH5R06BY-TR uses the DPAK (TO-252) package with 3 terminals and isolated cathode tab, while STTH5R06GY-TR uses D²PAK (TO-263) with larger thermal pad and different mechanical dimensions. Footprint, thermal pad layout, and solder stencil requirements differ significantly-PCB redesign is required for substitution.
What is the maximum allowable case temperature for continuous 5 A operation?
Per datasheet Table 1, IF(AV) = 5 A is rated at TC = 145 °C. With Rth(j-c) = 2.2 °C/W and Tj(max) = 175 °C, the maximum allowable case temperature is 175 °C − (5 A² × 0.12 Ω × 2.2 °C/W) ≈ 145.5 °C - matching the datasheet condition. Exceeding 145 °C case temperature requires derating.
Does STTH5R06BY-TR require a gate resistor or snubber network?
No. As a passive rectifier diode, it has no gate. However, due to its 35 ns trr and 6 A IRM, a small RC snubber (e.g., 100 Ω + 100 pF) across anode-cathode is recommended in hard-switched topologies with dV/dt > 100 V/ns to suppress voltage overshoot and reduce EMI.
Can STTH5R06BY-TR replace a standard FR107 in a 600 V flyback design?
Yes, but with critical trade-offs: STTH5R06BY-TR offers 3× faster trr (35 ns vs. ~500 ns), reducing turn-off loss and EMI, yet its VF is higher (1.5 V vs. ~1.3 V). In high-frequency (>60 kHz) designs, the net efficiency gain justifies the VF increase; in low-frequency, low-cost applications, FR107 remains acceptable.
