Product details
Overview
SR2060PT from Taiwan Semiconductor is a 20A, 60V Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring low forward voltage (0.70 V @ 10 A, 25°C), high surge capability (200 A IFSM), and junction temperature rating up to +150°C. It serves as a primary output rectifier in high-efficiency DC/DC converters and SMPS for industrial power supplies.
For engineers reviewing the SR2060PT datasheet, SR2060PT pinout, SR2060PT application, or SR2060PT equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, dual-die construction, 1.5 °C/W junction-to-case thermal resistance, and AEC-Q101 qualification availability - all critical for thermal management and automotive-grade reliability validation.
Technical Context
The SR2060PT employs a dual-die Schottky structure optimized for low conduction loss and fast switching, with guard ring protection enabling robust overvoltage tolerance. Its 60 V VRRM rating targets mid-voltage DC/DC stages where efficiency and thermal headroom are prioritized over ultra-high voltage blocking.
Thermal performance is defined by RθJC = 1.5 °C/W and TJ max = +150°C, supporting forced-air or heatsink-mounted operation in compact power modules. Reverse leakage remains ≤500 µA at 25°C and ≤10 mA at 100°C - critical for standby loss control in energy-efficient designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - defines maximum allowable reverse bias before breakdown in continuous operation |
| IF | 20 A - average forward current rating at case temperature ≤80°C, usable in 24–48 V output rails |
| VF @ 10 A, 25°C | 0.70 V - directly reduces conduction loss and improves system efficiency vs. silicon diodes |
| IFSM | 200 A - supports 8.3 ms half-sine surge, essential for input-capacitor inrush handling |
| RθJC | 1.5 °C/W - enables predictable thermal design with standard TO-247 heatsinking |
| TJ max | +150°C - allows operation in high-ambient environments such as enclosed industrial enclosures |
| IR @ 60 V, 25°C | ≤500 µA - ensures low standby power in always-on auxiliary supplies |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal through-hole package with isolated mounting tab; matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH06-M3 | Same 60 V VRRM, 20 A IF, TO-247AC package; VF = 0.69 V @ 10 A, but RθJC = 2.0 °C/W | Slightly higher thermal resistance limits power density in space-constrained layouts | Prefer SR2060PT where thermal margin is critical; VS-20CPH06-M3 acceptable with enhanced airflow |
| ON Semiconductor MUR2060CT | 60 V, 20 A, but fast recovery (not Schottky); VF ≈ 1.15 V, higher switching loss, no AEC-Q101 option | Higher conduction loss and EMI vs. Schottky; unsuitable for high-frequency, high-efficiency designs | SR2060PT preferred for >100 kHz topologies; MUR2060CT only if cost-driven and thermal budget permits |
Compared with VS-20CPH06-M3 and MUR2060CT, the SR2060PT delivers superior thermal performance (1.5 vs. 2.0 °C/W) and lower conduction loss, making it optimal for thermally constrained, high-efficiency 60 V rectification where Schottky behavior is mandatory.

FAQ
What is the maximum junction temperature rating for the SR2060PT?
The SR2060PT has a maximum junction temperature (TJ max) of +150°C, verified per datasheet Absolute Maximum Ratings. This allows operation in high-ambient environments such as enclosed industrial power supplies or under-hood automotive locations when properly heatsinked. The SR2060PT maintains rated performance up to this limit, provided case temperature and thermal resistance constraints are respected in layout.
Is the SR2060PT pin-compatible with other parts in the SR20xxPT family?
Yes, all SR20xxPT variants - including SR2020PT through SR20150PT - share identical TO-247AD (TO-3P) packaging and 3-pin pinout (Anode, Cathode, Case). The SR2060PT can be substituted within the same footprint for different voltage grades without PCB changes, though electrical validation for VRRM, VF, and IR is required per application.
Does the SR2060PT have AEC-Q101 qualification?
The base SR2060PT is not AEC-Q101 qualified; however, the variant SR2060PTH (with 'H' suffix) is explicitly listed as AEC-Q101 qualified in the ordering information. Engineers requiring automotive-grade reliability must specify SR2060PTH - the SR2060PT itself meets industrial standards but lacks formal automotive stress-test certification.
What is the typical forward voltage of the SR2060PT at 20 A load?
The SR2060PT datasheet specifies VF = 0.70 V maximum at IF = 10 A and TJ = 25°C. At 20 A, VF rises due to resistive and thermal effects; extrapolation using typical forward characteristics curves shows VF ≈ 0.82–0.88 V depending on junction temperature. For precise design, use the Fig.4 Typical Forward Characteristics curve with actual TJ estimation.
How does the guard ring feature improve reliability of the SR2060PT?
The guard ring in the SR2060PT provides edge termination that suppresses premature avalanche breakdown at the die periphery, increasing ruggedness against repetitive overvoltage transients and improving long-term reliability in noisy power environments. This eliminates need for external clamping in many SMPS and adapter applications, as confirmed by TSC's characterization under surge and line-transient conditions.
