Product details
Overview
STPS160UY from STMicroelectronics is an AEC-Q101-qualified automotive Schottky rectifier in SMB (DO-214AA) package, rated for 1 A average forward current and 60 V repetitive peak reverse voltage, with max 0.57 V forward voltage at 125 °C and 1 A, designed for low-voltage, high-frequency DC/DC converters and polarity protection in engine control units.
For engineers reviewing the STPS160UY datasheet, STPS160UY pinout, STPS160UY application, or STPS160UY equivalent, key selection criteria include its 0.57 V VF (max) at 125 °C, 23 °C/W junction-to-lead thermal resistance, avalanche capability up to 2400 W (1 µs), and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This Schottky rectifier operates as a unidirectional power switching device with negligible switching losses due to majority-carrier conduction, enabling efficient operation in high-frequency (>100 kHz) topologies. Its low VF and high IFSM (75 A) support robust freewheeling and reverse-polarity protection in 12 V automotive systems.
The device features specified avalanche capability (2400 W, 1 µs pulse), ECOPACK®2 compliance, and thermal performance validated across -40 °C to +150 °C junction temperature range. Junction-to-lead thermal resistance of 23 °C/W (SMB) enables direct PCB copper pad heat sinking without external heatsinks in typical automotive ambient conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS1C200MT1G | Same SMB package, 200 V VRRM, 1 A IF(AV), VF = 0.55 V (typ) at 125 °C | Higher reverse voltage rating suits 24 V commercial vehicles; lower surge rating (IFSM = 30 A) | Select when 24 V system compatibility or higher reverse margin is required; not AEC-Q101 qualified |
| Vishay VS-1EQH06-M3/45 | SMB package, 60 V VRRM, 1 A IF(AV), VF = 0.62 V (max) at 125 °C, AEC-Q101 qualified | Higher VF increases conduction loss by ~85 mW at 1 A; identical thermal resistance (23 °C/W) | Select when second-source validation is needed; verify VF impact on thermal budget in sealed enclosures |
Compared with NSS1C200MT1G and VS-1EQH06-M3/45, STPS160UY offers the lowest VF (0.57 V max) among AEC-Q101-qualified 60 V SMB Schottkys, delivering superior thermal performance in space-constrained engine bay modules where junction temperature must stay below 150 °C.

FAQ
What is the maximum junction temperature for continuous operation?
The STPS160UY supports continuous operation up to +150 °C junction temperature, verified per AEC-Q101 stress testing. This allows placement near heat-generating components in ECUs without active cooling, provided PCB copper area meets minimum 4 cm² per lead per Figure 13 in the datasheet.
Is STPS160UY suitable for synchronous rectification?
No-STPS160UY is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. It functions as a freewheeling or polarity-protection diode. Synchronous rectification requires gate-driven MOSFETs and timing control circuitry external to this device.
Does it require a heatsink in standard automotive applications?
No external heatsink is required when mounted on FR4 PCB with ≥4 cm² of 35 µm copper per lead (per Figure 13). The 23 °C/W Rth(j-l) enables sufficient self-cooling for 1 A continuous current in ambient temperatures up to +85 °C.
How does its avalanche capability compare to standard rectifiers?
Unlike standard PN-junction rectifiers, STPS160UY is fully specified for single-pulse avalanche energy absorption (2400 W at 1 µs), making it suitable for load-dump clamping without additional TVS devices-standard rectifiers lack defined avalanche ratings and may fail catastrophically under such stress.
