Product details
Overview
SRT13HA1G 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, used in automotive-grade DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the SRT13HA1G datasheet, SRT13HA1G pinout, SRT13HA1G application, or SRT13HA1G equivalent, key selection criteria include its AEC-Q101 qualification, low VF for efficiency-critical 12 V–24 V systems, TJ max of +150°C, and TS-1 package compatibility with high-density power layouts.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring structure to enhance overvoltage robustness and surge immunity. Its 25 A IFSM rating supports transient load demands in automotive power rails, while the 50 °C/W RθJA enables thermal management without heatsinking in ambient temperatures up to +85°C.
The device operates across -55°C to +150°C junction range and exhibits 110 pF junction capacitance at 1 MHz/4 V, supporting high-frequency switching (>100 kHz) with minimal capacitive loss. Reverse leakage remains ≤500 µA at 25°C and ≤10 mA at 100°C under rated 30 V VR.

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 (larger footprint, higher RθJA = 65 °C/W). | Not AEC-Q101 qualified; intended for commercial/industrial use only. | Select when automotive qualification is not required and board space permits larger outline. |
| ON Semiconductor SB130 | 30 V VRRM, 1 A IF, DO-41 through-hole package; VF = 0.55 V, but no AEC-Q101 certification. | Lacks automotive qualification and surface-mount compatibility; requires wave soldering. | Choose for cost-sensitive prototyping or legacy through-hole designs where AEC-Q101 is not mandated. |
Compared with VS-1EQH03-M3/45 and SB130, the SRT13HA1G uniquely combines AEC-Q101 qualification, TS-1 surface-mount form factor, and 50 °C/W thermal resistance-making it the only option suitable for production automotive modules requiring both reliability and high-density layout.

FAQ
What is the maximum junction temperature rating for the SRT13HA1G?
The SRT13HA1G has a maximum junction temperature (TJ) rating of +150°C, validated per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings without thermal derating below 1 A continuous current, provided PCB copper area meets minimum thermal pad guidelines specified in the TS-1 outline drawing.
Is the SRT13HA1G pin-compatible with other SRT1x devices?
Yes-the SRT13HA1G shares identical TS-1 package dimensions, anode/cathode pin assignment, and polarity marking (cathode band) with all SRT12–SRT115 variants. Voltage ratings differ across the family, but mechanical and soldering interfaces are fully interchangeable, enabling design reuse across 20 V–150 V requirements using the same footprint.
Does the SRT13HA1G meet RoHS and halogen-free requirements?
Yes-the SRT13HA1G complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and terminals feature pure tin plating qualified to J-STD-002 for solderability, confirming full environmental compliance for automotive and industrial end equipment.
What is the surge current rating of the SRT13HA1G and how is it tested?
The SRT13HA1G supports a non-repetitive peak forward surge current (IFSM) of 25 A, measured per JEDEC JESD201 with an 8.3 ms single half-sine waveform superimposed on rated load. This rating validates robustness against automotive load-dump and cold-crank transients defined in ISO 16750-2, ensuring survival without parametric shift or catastrophic failure.
How does the guard ring structure in the SRT13HA1G improve reliability?
The guard ring in the SRT13HA1G mitigates edge-related avalanche breakdown by controlling electric field distribution at the die periphery. This enhances overvoltage tolerance during transient events and improves long-term stability under repeated surge stress-critical for automotive applications where voltage spikes exceeding VRRM occur routinely in real-world electrical systems.
