Product details

Overview

SRS1060H from Taiwan Semiconductor is a 10A, 60V AEC-Q101-qualified Schottky barrier rectifier in TO-263AB (D2PAK) package, featuring 0.70V forward voltage at 5A/25°C, 120A surge capability, and dual-die construction for high-efficiency DC/DC conversion and reverse battery protection in automotive lighting systems.

For engineers reviewing the SRS1060H datasheet, SRS1060H pinout, SRS1060H application, or SRS1060H equivalent, key selection criteria include its 60V V_RRM, 10A continuous forward current, 2°C/W junction-to-case thermal resistance, 10mA reverse leakage at 125°C, and AEC-Q101 qualification for under-hood automotive use.

Technical Context

The SRS1060H implements a dual-die Schottky structure optimized for low conduction loss and fast switching in high-frequency power conversion. Its 60V V_RRM rating and 0.70V V_F at 5A enable efficient operation in 48V automotive subsystems and compact DC/DC converters.

Thermally, it delivers 2°C/W R_θJC via the TO-263AB copper tab, supporting 10A continuous current with junction temperature maintained ≤125°C under typical PCB heatsinking. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity.

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-10BQ060-M3/45	Same 60V V_RRM, 10A I_F, but TO-220AC package; higher R_θJC = 3.5°C/W; no AEC-Q101 certification.	Requires larger heatsink area; not qualified for automotive under-hood deployment.	Select only for industrial or consumer applications where qualification and thermal performance are less critical.
ON Semiconductor SB1060-T3	60V V_RRM, 10A I_F, TO-263AB package, but V_F = 0.75V @ 5A; AEC-Q101 qualified; R_θJC = 2.5°C/W.	Slightly higher conduction loss and thermal resistance; same automotive qualification level.	Acceptable alternative if 50mV higher V_F and 0.5°C/W higher thermal resistance are tolerable in thermal budget.

Compared with VS-10BQ060-M3/45 and SB1060-T3, the SRS1060H offers superior thermal performance (2°C/W), lower forward voltage (0.70V), and full AEC-Q101 compliance-making it the preferred choice for space-constrained, high-reliability automotive power designs.

FAQ

What is the maximum junction temperature rating for the SRS1060H?

The SRS1060H has a maximum junction temperature (T_J) rating of +125°C, validated per AEC-Q101 stress testing protocols. This rating applies under continuous 10A forward current with proper PCB thermal management-specifically a minimum 400 mm² copper pour connected to the cathode tab. Operation above this limit risks parametric shift and accelerated degradation.

Is the SRS1060H pin-compatible with other parts in the SRS10xxH series?

Yes-the SRS1060H shares identical TO-263AB (D2PAK) mechanical footprint and pinout with all members of the SRS1020H–SRS10150H family, including SRS1050H and SRS1090H. Anode 1, Anode 2, and Cathode (tab) positions are fixed across the series, enabling voltage-rating interchangeability on the same PCB layout without redesign.

Does the SRS1060H require a heatsink for 10A continuous operation?

The SRS1060H does not require an external heatsink when mounted on a standard 4-layer PCB with ≥400 mm² of 2-oz copper connected to the cathode tab. Its 2°C/W R_θJC and 125°C T_J max allow 10A continuous current at ambient temperatures up to 85°C-provided the copper area is unobstructed and not shared with other high-power components.

What is the reverse leakage current specification for the SRS1060H at elevated temperature?

At rated 60V reverse voltage and junction temperature of 125°C, the SRS1060H exhibits a maximum reverse leakage current (I_R) of 10 µA per diode. This value is confirmed in the Electrical Specifications table and reflects worst-case behavior under automotive under-hood thermal conditions-critical for minimizing standby power loss in always-on vehicle modules.

How does the guard ring feature improve reliability in the SRS1060H?

The guard ring in the SRS1060H enhances edge termination robustness by distributing electric field stress away from the active junction periphery. This prevents premature avalanche breakdown during voltage transients-such as 100V+ load dump events in automotive systems-thereby extending operational lifetime and ensuring stable 60V blocking capability over 15 years of vehicle service.
