Product details
Overview
SRT13HR0G from Taiwan Semiconductor is a 30 V, 1 A AEC-Q101-qualified Schottky barrier rectifier in TS-1 package, featuring 0.55 V forward voltage at 1 A and 500 µA reverse leakage at 25°C, designed for high-efficiency DC/DC converters and automotive-grade power adapters.
For engineers reviewing the SRT13HR0G datasheet, SRT13HR0G pinout, SRT13HR0G application, or SRT13HR0G equivalent, key selection criteria include its 30 V repetitive peak reverse voltage, AEC-Q101 qualification, TS-1 thermal resistance of 50°C/W, low VF for reduced conduction loss, and suitability for space-constrained 1 A switching power supplies.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring overvoltage protection and pure tin-plated leads compliant with J-STD-002 solderability. Its junction temperature range spans –55°C to +150°C, supporting operation in under-hood automotive environments.
Electrical behavior is defined by low forward voltage (0.55 V typ. @ 1 A, 25°C), low reverse current (500 µA max @ 30 V, 25°C), and 25 A non-repetitive surge capability - enabling robust transient handling in SMPS flyback and buck topologies.
Key Specifications

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-1EQH03-M3/45 | Same 30 V VRRM, 1 A IF, but TO-277 package (RθJA = 65°C/W); VF = 0.52 V typ. | Higher thermal resistance requires layout review for same ambient; identical AEC-Q101 qualification. | Prefer when existing TO-277 footprint exists; verify thermal margin at 1 A in target enclosure. |
| ON Semiconductor SB130 | 30 V VRRM, 1 A IF, DO-214AA package; VF = 0.54 V typ.; no AEC-Q101 qualification. | Lacks automotive qualification; higher RθJA (~70°C/W); lower cost for industrial-only use. | Select only for non-automotive applications where qualification is not required and thermal headroom permits. |
Compared with VS-1EQH03-M3/45 and SB130, SRT13HR0G uniquely combines AEC-Q101 qualification, TS-1 footprint, and 50°C/W thermal resistance - making it optimal for space-limited automotive and industrial DC/DC designs needing verified reliability and thermal performance.

FAQ
What is the maximum junction temperature rating for SRT13HR0G?
The SRT13HR0G has a maximum junction temperature (TJ) of +150°C, validated per AEC-Q101 requirements. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. The device's thermal design - including 50°C/W RθJA and TS-1 package - ensures this limit is maintained under 1 A DC load at ambient temperatures up to 75°C without forced cooling. SRT13HR0G must be operated within this TJ limit to maintain long-term reliability.
Is SRT13HR0G pin-compatible with other SRT1x variants?
Yes, all SRT1x devices including SRT13HR0G share identical TS-1 package dimensions, anode/cathode terminal locations, and polarity marking (cathode band). Voltage ratings differ across the family (e.g., SRT12 = 20 V, SRT13HR0G = 30 V), but mechanical and solder footprint compatibility is maintained. SRT13HR0G can be substituted for other SRT1x parts in the same footprint when electrical parameters - especially VRRM and VF - meet circuit requirements. No PCB changes are needed for mechanical replacement.
Does SRT13HR0G require a heatsink for 1 A continuous operation?
No, SRT13HR0G does not require a heatsink for 1 A continuous operation under typical conditions. With a junction-to-ambient thermal resistance of 50°C/W and maximum junction temperature of +150°C, it supports full-rated current at ambient temperatures up to 75°C on standard FR-4 PCB with minimum copper pour. Derating begins above that ambient; thermal simulation or testing is recommended for enclosures exceeding 75°C ambient or with limited airflow. SRT13HR0G's TS-1 package is optimized for self-cooling in compact power designs.
What does the "H" and "R0G" suffix mean in SRT13HR0G?
In SRT13HR0G, "H" denotes AEC-Q101 qualification per the ordering code table in the datasheet; "R0G" indicates green (halogen-free) molding compound compliant with IEC 61249-2-21. The base "SRT13" identifies the 30 V variant within the SRT1x family. Together, SRT13HR0G specifies a 30 V, AEC-Q101-qualified, RoHS- and halogen-free Schottky rectifier in TS-1 package. This full designation ensures traceability to exact material, qualification, and environmental compliance levels required for automotive procurement.
How does the guard ring feature improve reliability in SRT13HR0G?
The guard ring in SRT13HR0G enhances edge termination robustness by distributing electric field stress away from the active junction periphery. This prevents localized avalanche breakdown during voltage transients - such as load dump pulses in automotive systems - thereby extending device lifetime and improving consistency in high-reliability applications. Verified through AEC-Q101 stress testing, the guard ring directly contributes to SRT13HR0G's ability to sustain 30 V reverse bias under harsh conditions without parameter drift or failure. It is a structural feature intrinsic to the die design, not an external component.
