STMicroelectronics STPS30L60CTN

Overview

STPS30L60CTN from STMicroelectronics is a dual-center-tap Schottky rectifier in TO-220AB narrow leads package, rated for 60 V repetitive peak reverse voltage, 15 A average forward current per diode (30 A total), and maximum forward voltage of 0.56 V at 15 A and 125 °C. It delivers low conduction loss and negligible switching losses for high-frequency DC–DC converters in telecom power supplies.

For engineers reviewing the STPS30L60CTN datasheet, STPS30L60CTN pinout, STPS30L60CTN application, or STPS30L60CTN equivalent, this device is selected for high-efficiency secondary-side rectification where thermal resistance (R_th(j-c) = 1.5 °C/W per diode) and avalanche capability (V_ARM = 80 V, P_ARM = 7800 W) are critical to system reliability under transient overload.

Technical Context

This dual-diode Schottky rectifier integrates two independent anode-cathode paths sharing a common cathode terminal (center-tap configuration), enabling synchronous or interleaved rectification topologies. Its low dV/dt rating (10,000 V/µs) supports fast-switching operation without spurious turn-on in high-noise environments.

The device features specified avalanche capability with pulse-tested V_ARM = 80 V and I_AR ≤ 29 A (t_p < 1 µs), validated per AN1768 and AN2025. Thermal design relies on junction-to-case conduction (1.5 °C/W per diode) and coupling resistance (0.1 °C/W) to manage simultaneous conduction in both diodes.

FAQ

What is the maximum junction temperature and how does it affect derating?

The absolute maximum junction temperature (T_j) is 150 °C. Derating begins above T_c = 130 °C for TO-220AB narrow leads packages: average forward current must be reduced linearly to zero at 150 °C junction temperature. This ensures thermal runaway prevention per condition dP_tot/dT_j < 1/R_th(j-a).

Can STPS30L60CTN replace standard silicon rectifiers in existing designs?

Yes, but only if the circuit operates below 60 V reverse voltage and benefits from Schottky advantages: no reverse recovery charge, lower V_F, and higher switching frequency tolerance. Layout must accommodate its center-tap pinout (A1/A2/K), and thermal design must account for its 1.5 °C/W R_th(j-c) - not the higher thermal resistance of legacy silicon devices.

Is avalanche testing performed per industry standards?

Yes - avalanche validation follows ST's internal qualification per application notes AN1768 and AN2025, measuring V_ARM and P_ARM under controlled 1 µs pulses at T_j < 150 °C. The 80 V V_ARM rating is guaranteed across the production lot, not just typical.

What torque value should be used when mounting the TO-220AB narrow leads package?

The recommended mechanical mounting torque for the TO-220AB narrow leads package is 0.4–0.6 N·m. Exceeding 0.6 N·m risks cracking the epoxy body or deforming the leads; torque below 0.4 N·m may compromise thermal contact to the heatsink, raising junction temperature beyond rated limits.
