Product details

Overview

SRAS2060 from Taiwan Semiconductor is a 20 A, 60 V Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for high-efficiency DC/DC converters and SMPS secondary-side rectification with 0.70 V max forward voltage at 20 A and 25°C, 330 A surge capability, and 1.5°C/W junction-to-case thermal resistance.

For engineers reviewing the SRAS2060 datasheet, SRAS2060 pinout, SRAS2060 application, or SRAS2060 equivalent, this device is selected for high-current, low-VF switching rectification where thermal performance, surge robustness, and RoHS/halogen-free compliance are critical in industrial and computing power supplies.

Technical Context

The SRAS2060 implements a single-die Schottky structure with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 60 V repetitive peak reverse voltage (V_RRM) and 42 V RMS reverse voltage define its use in mid-voltage secondary-side topologies.

Thermally, it delivers 1.5°C/W R_θJC, enabling direct heatsink mounting in high-power density designs; reverse leakage is limited to 500 µA at 25°C and 10 mA at 100°C under rated V_R, supporting stable operation across extended temperature ranges.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum non-repetitive reverse blocking voltage; sets upper limit for secondary-side flyback or LLC rectifier voltage stress
I_F	20 A - Continuous average forward current at case temperature ≤ 110°C; defines steady-state conduction rating
I_FSM	330 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload handling
V_F (max)	0.70 V @ 20 A, 25°C - Low conduction loss enabling >95% efficiency in high-frequency DC/DC stages
T_J max	+150°C - Maximum junction temperature; allows operation in thermally constrained enclosures with margin
R_θJC	1.5°C/W - Thermal resistance from junction to case; enables direct thermal interface to heatsink without thermal pad compromise
I_R (max)	500 µA @ 60 V, 25°C - Low leakage preserves efficiency in standby and light-load conditions

Pinout & Package

Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with anode, cathode, and exposed thermal pad (cathode-connected). Moisture sensitivity level 1 per J-STD-020; RoHS and halogen-free compliant.

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 V_RRM, 20 A I_F, but TO-220AC package; higher R_θJC = 2.5°C/W	Requires through-hole PCB layout and external heatsink; unsuitable for ultra-thin adapters	Select when legacy through-hole assembly or lower-cost tooling is prioritized over thermal density
ON Semiconductor SB2060	Identical V_RRM/I_F ratings, same TO-263AB package, but 0.72 V V_F (max) and 600 µA I_R at 25°C	Slightly higher conduction loss and leakage; validated for automotive-grade temp cycling (-40°C to +125°C)	Select when AEC-Q101 qualification is mandatory, accepting minor efficiency trade-off

Compared with VS-20CPH06-M3 and SB2060, the SRAS2060 offers the lowest thermal resistance and tightest V_F spec in its class, making it optimal for space-constrained, high-efficiency industrial and computing power supplies where thermal headroom and light-load efficiency are design-critical.

FAQ

What is the maximum junction temperature rating for the SRAS2060?

The SRAS2060 has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows sustained operation in high-ambient environments when mounted to an adequate heatsink. Derating curves confirm usable current capacity down to 110°C case temperature at full 20 A rating. The SRAS2060 must not exceed this limit to ensure long-term reliability and parametric stability.

Does the SRAS2060 have a guarded die structure?

Yes, the SRAS2060 incorporates a guard ring structure explicitly stated in its features list to enhance overvoltage protection. This design mitigates edge breakdown under transient voltage stress, improving ruggedness without sacrificing V_RRM rating. The guard ring is integral to the silicon die layout and confirmed in the "Features" section of the Taiwan Semiconductor SRAS2020–SRAS20150 datasheet revision M2103.

What is the forward voltage specification for the SRAS2060 at 20 A and 25°C?

The SRAS2060 has a maximum forward voltage (V_F) of 0.70 V at 20 A and 25°C, as specified in the Electrical Specifications table under "SRAS2050 / SRAS2060" column. This value is measured using a 0.3 ms pulse test condition and represents the worst-case conduction loss for thermal and efficiency calculations. Typical V_F is lower, but design margins must use the 0.70 V max value.

Is the SRAS2060 RoHS and halogen-free compliant?

Yes, the SRAS2060 is RoHS compliant and halogen-free per IEC 61249-2-21, as documented in the "Features" section of the official datasheet. Lead finish is matte tin, and the molding compound meets UL 94V-0 flammability rating. These compliance attributes are verified for the TO-263AB package variant and apply to all units shipped under ordering code SRAS2060.

What is the surge current rating for the SRAS2060?

The SRAS2060 is rated for a non-repetitive peak forward surge current (I_FSM) of 330 A, tested with an 8.3 ms single half-sine wave superimposed on rated load. This rating is defined in the Absolute Maximum Ratings table and applies at T_A = 25°C. It supports robust operation during power-up inrush, short-circuit recovery, and line transients in SMPS and DC/DC applications using the SRAS2060.
