STMicroelectronics STPS30M60SR

Overview

STPS30M60SR from STMicroelectronics is a single silicon Schottky power rectifier in I2PAK package, rated for 30 A average forward current and 60 V repetitive peak reverse voltage, with typical forward voltage drop of 0.380 V at 125 °C and 30 A. It is avalanche-rated (80 V, 1 µs), thermally optimized for conduction cooling, and deployed in high-frequency AC-DC adapters for notebooks and game stations.

For engineers reviewing the STPS30M60SR datasheet, STPS30M60SR pinout, STPS30M60SR application, or STPS30M60SR equivalent, key selection criteria include low VF at high junction temperature, avalanche energy capability (34.4 kW peak), thermal resistance (0.9 °C/W j-c), and compatibility with TO-220AB/D2PAK footprint variants for layout flexibility.

Technical Context

The STPS30M60SR operates as a unidirectional, majority-carrier Schottky rectifier with no minority-carrier storage delay-enabling zero-recovery switching essential for >100 kHz SMPS topologies. Its metal-semiconductor junction delivers low forward conduction loss while maintaining stable reverse leakage (<100 mA at 125 °C, VR = VRRM − 35 V).

Thermal design is constrained by R_th(j–c) = 0.9 °C/W and T_j(max) = 150 °C, requiring mechanical mounting to heatsink via the exposed tab (terminal 3). Avalanche robustness is validated per AN1768/AN2025, supporting transient overvoltage handling without derating in adapter primary-side clamp circuits.

FAQ

What is the maximum allowable case temperature for continuous 30 A operation?

The datasheet specifies I_F(AV) = 30 A at T_c = 130 °C. Exceeding this case temperature risks exceeding T_j(max) = 150 °C given R_th(j–c) = 0.9 °C/W. Therefore, sustained 30 A operation requires case temperature ≤130 °C, verified via thermocouple on the tab surface under worst-case ambient and airflow conditions.

Can STPS30M60SR replace TO-220AB-packaged STPS30M60ST in the same PCB layout?

No-STPS30M60SR uses I2PAK (TO-263) with different pad dimensions and thermal pad geometry than TO-220AB. The I2PAK has a wider body (E = 10–10.4 mm vs. TO-220AB's 10.4 mm height), different lead spacing, and requires a dedicated land pattern per Table 7. Mechanical interference and solder joint reliability would be compromised in a direct footprint swap.

Is the avalanche rating tested per JEDEC JESD22-A114 or proprietary ST methodology?

ST validates avalanche performance per internal test method aligned with AN1768 and AN2025, which define pulse conditions (tp < 1 µs, I_AR ≤ 129 A, T_j < 150 °C) and measurement protocols. While not certified to JEDEC JESD22-A114, the 80 V V_ARM rating is production-tested and guaranteed across the full temperature range, with published SOA curves in Figure 12.

Does the I2PAK package provide electrical isolation between the tab and leads?

No-the tab (terminal 3) is electrically connected to the cathode (terminal 2) inside the package. There is no internal isolation; the tab must be treated as a live cathode node. PCB layout must ensure adequate creepage/clearance to other traces, and any heatsink must be insulated unless referenced to the cathode potential.
