Product details
Overview
STPS30170CFP from STMicroelectronics is a dual center-tap high-voltage Schottky rectifier optimized for high-frequency switch-mode power supplies, featuring 170 V repetitive peak reverse voltage, 2 × 15 A average forward current per diode, and 0.69 V typical forward voltage drop at 125 °C/15 A - enabling low conduction loss in PFC and output rectification stages of industrial AC-DC adapters.
For engineers reviewing the STPS30170CFP datasheet, STPS30170CFP pinout, STPS30170CFP application, or STPS30170CFP equivalent, key selection criteria include junction-to-case thermal resistance (0.95 °C/W total for D²PAK), avalanche capability (750 W, 10 µs), and ECOPACK®2 compliance - critical for thermally constrained, high-reliability 1–3 kW power converters.
Technical Context
This dual-diode Schottky rectifier integrates two independent anode-cathode paths sharing a common cathode terminal (center-tap configuration), supporting synchronous rectification and interleaved topologies. Its low VF/IR trade-off - 0.69 V typ. @ 125 °C/15 A and ≤20 µA IR @ 25 °C/VRRM - targets efficiency-sensitive SMPS where thermal runaway risk is mitigated by (dPtot/dTj) < (1/Rth(j-a)) design condition.
The device operates up to +175 °C junction temperature with specified avalanche energy handling (PARM = 750 W, tp = 10 µs), and supports both D²PAK and TO-247 packages - with Rth(j-c) per diode at 1.6 °C/W (D²PAK) and 1.5 °C/W (TO-247), enabling direct heatsink mounting via screw torque (0.55 N·m recommended).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 170 V - Withstands repetitive reverse voltage up to 170 V, suitable for 120/230 VAC input-derived rails with margin. |
| IF(AV) per diode | 15 A - Sustains continuous 15 A DC forward current per diode at TC = 150 °C, enabling 30 A total device rating. |
| VF typ. @ 125 °C | 0.69 V - Low forward drop reduces conduction loss in high-duty-cycle operation, improving system efficiency. |
| IR max @ 125 °C | 20 mA - Controlled leakage ensures stable blocking performance under elevated temperature stress. |
| Tj max | +175 °C - Enables operation in high-ambient environments without derating, supporting compact thermal design. |
| Rth(j-c) total | 0.95 °C/W - Low thermal resistance from junction to case allows effective heat transfer to external heatsink. |
| PARM | 750 W - Rated repetitive avalanche power supports transient overvoltage resilience in flyback and LLC resonant converters. |
Pinout & Package
D²PAK (TO-263) package: surface-mount, isolated tab, 3-terminal configuration with dual anodes and shared cathode. Thermal pad on underside requires soldered copper area per Figure 11 footprint (8.6–9.35 mm × 10.0–10.55 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30H100CG-TR | 100 V VRRM, same D²PAK package, 0.65 V VF typ. @ 125 °C/15 A | Limited to ≤100 V DC bus applications; lower voltage stress but insufficient for 170 V designs. | Select when system VRRM requirement is ≤100 V and lowest possible VF is prioritized. |
| VS-30CPH07-M3 | 70 V VRRM, TO-220AC package, 0.72 V VF @ 125 °C/15 A, no avalanche rating | Not rated for 170 V operation; lacks avalanche specification and higher thermal resistance (Rth(j-c) = 2.0 °C/W). | Use only in legacy 70 V designs where footprint compatibility and cost outweigh thermal/avalanche requirements. |
Compared with STPS30H100CG-TR and VS-30CPH07-M3, STPS30170CFP uniquely combines 170 V rating, avalanche capability, and sub-0.7 V VF at elevated temperature - making it the sole option for thermally aggressive, high-voltage SMPS where transient resilience and conduction efficiency are jointly critical.

FAQ
What is the correct mounting torque for STPS30170CFP in TO-247 package?
The recommended torque for the TO-247 variant (e.g., STPS30170CW) is 0.55 N·m, with a maximum allowable torque of 1.0 N·m. Exceeding this may damage the leadframe or compromise thermal interface integrity. D²PAK variants (e.g., STPS30170CG-TR) are surface-mounted and do not require mechanical torque - thermal performance depends on solder paste volume and PCB copper area per ST's recommended footprint.
Does STPS30170CFP support parallel operation of its two diodes?
Yes - the dual diodes share only the cathode terminal and have electrically isolated anodes (A1 and A2), enabling independent control and parallel use in interleaved or multi-phase rectification. Thermal coupling between diodes is accounted for in Rth(c) = 0.3 °C/W, so simultaneous full-load operation requires derating per ΔTj = P₁×Rth(j-c) + P₂×Rth(c) to avoid exceeding 175 °C Tj.
How is avalanche capability tested and rated for STPS30170CFP?
Avalanche capability is validated per IEC 61643-31 using unclamped inductive switching tests: 750 W peak power at Tj = 125 °C, tp = 10 µs, with sinusoidal current waveform. The rating applies to repetitive events and is verified across process lots - not a one-time surge rating. Designers must ensure external circuit limits di/dt and clamping voltage to stay within PARM limits during fault conditions.
Is STPS30170CFP suitable for synchronous rectification control schemes?
No - STPS30170CFP is a passive Schottky diode, not a MOSFET-based synchronous rectifier. It cannot be actively gated. However, its zero-recovery characteristic and low VF make it ideal as a self-commutated replacement for slower diodes in circuits where gate drive complexity or cost precludes MOSFET-based synchronous rectification - especially in high-frequency flyback or forward converters.
