STMicroelectronics STPS5L60RL

Overview

STPS5L60RL from STMicroelectronics is a 5 A average forward current, 60 V repetitive peak reverse voltage axial-lead Schottky rectifier in DO-201AD package, featuring 0.42 V typical forward voltage at 5 A and 125 °C, low thermal resistance (15 °C/W junction-to-lead), and avalanche-rated operation up to 144 W for 10 µs pulses - deployed in notebook adapters and telecom battery chargers where space and conduction loss are critical.

For engineers reviewing the STPS5L60RL datasheet, STPS5L60RL pinout, STPS5L60RL application, or STPS5L60RL equivalent, key selection criteria include forward voltage drop at high temperature, surge current capability (100 A IFSM), junction-to-ambient thermal resistance under PCB copper area constraints, and ECOPACK2 compliance for RoHS-compliant industrial power supplies.

Technical Context

This Schottky rectifier operates without minority-carrier storage, eliminating reverse recovery time and associated switching losses - enabling efficient high-frequency DC/DC conversion up to several hundred kHz. Its low VF and low Rth(j-l) support compact thermal design in unheatsinked applications like wall adapters.

The device is rated for 150 °C maximum junction temperature and exhibits controlled reverse leakage (<100 µA at 125 °C, VR = 60 V), with avalanche energy handling validated per PARM = 144 W at Tj = 125 °C and tp = 10 µs - critical for transient robustness in battery charger input stages.

Key Specifications

FAQ

Is STPS5L60RL suitable for synchronous rectification circuits?

No - STPS5L60RL is a passive Schottky diode, not a synchronous rectifier IC. It functions as a unidirectional freewheeling or output rectifier. For synchronous rectification, discrete MOSFETs or dedicated SR controllers (e.g., STSR3) must be used in conjunction with this diode as a backup or clamp element.

What is the maximum allowable PCB copper area for thermal optimization of STPS5L60RL in DO-201AD?

Per Figure 14 in DS2741, Rth(j-a) drops from 75 °C/W (no copper) to ~42 °C/W with 100 mm² (1 cm²) copper per lead on FR4. Beyond 200 mm², diminishing returns occur; 4 cm² total (2 cm² per lead) achieves ~30 °C/W, sufficient for 5 A at 70 °C ambient without forced air.

Does STPS5L60RL require derating at elevated ambient temperatures?

Yes - IF(AV) must be linearly derated above 80 °C ambient. At 100 °C, maximum average current drops to ~3.8 A (per Fig. 2); at 125 °C, it falls to ~2.3 A. Derating follows the curve in DS2741 page 3, based on thermal resistance and junction temperature limit of 150 °C.

Can STPS5L60RL replace STPS6L60 in existing designs?

No - STPS6L60 is rated for 6 A IF(AV), while STPS5L60RL is rated for 5 A. Substitution risks thermal overload under full-load conditions. Though both share same VRRM and package, the 20% current margin reduction impacts reliability in sustained 5–6 A applications such as 65 W adapters.
