Product details
Overview
SRA1630 from Taiwan Semiconductor is a 16A, 30V repetitive peak reverse voltage Schottky barrier rectifier in TO-220AC package, delivering low forward voltage (0.55 V at 16 A, 25°C) and high surge capability (200 A, 8.3 ms), used in automotive-grade SMPS and DC-DC converters requiring high efficiency and AEC-Q101 compliance.
For engineers reviewing the SRA1630 datasheet, SRA1630 pinout, SRA1630 application, or SRA1630 equivalent, key selection factors include its 30 V VRRM, 5 °C/W junction-to-case thermal resistance, 15 mA reverse leakage at 100°C, guard ring overvoltage protection, and AEC-Q101 qualification status when ordering the 'H' variant.
Technical Context
The SRA1630 employs a single-die Schottky structure optimized for low conduction loss in medium-voltage switching applications. Its 0.55 V forward voltage at rated current and 5 °C/W thermal resistance enable efficient heat dissipation in compact power supplies.
Designed with a guard ring for transient overvoltage robustness and qualified to AEC-Q101 (H-version), it supports operation up to 150°C junction temperature and withstands 200 A non-repetitive surge currents-critical for automotive and industrial DC-DC converter front-end rectification.
Key Specifications

| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 24 V system rails |
| IF | 16 A - Continuous average forward current; supports high-power adapter and converter output stages |
| VF | 0.55 V @ 16 A, 25°C - Low conduction loss reduces thermal load and improves system efficiency |
| IFSM | 200 A @ 8.3 ms - Handles inrush and fault surges without failure in SMPS input rectification |
| RθJC | 5 °C/W - Enables effective heatsink coupling for thermal management in enclosed power modules |
| TJ max | 150°C - Extended junction rating supports under-hood automotive environments and high-ambient industrial use |
| IR @ 100°C | 15 mA - Controlled reverse leakage ensures stable performance at elevated temperatures |
Pinout & Package
TO-220AC package: single-ended anode-cathode configuration with isolated tab (cathode-connected), matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and 0.56 N·m maximum mounting torque.

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-16CTQ030PBF | Same 30 V VRRM, 16 A IF, TO-220AC; VF = 0.52 V @ 16 A (slightly lower), RθJC = 4.5 °C/W | No AEC-Q101 option available; not qualified for automotive use | Select for cost-sensitive industrial power where automotive qualification is unnecessary |
| ON Semiconductor MUR1630CT | 30 V VRRM, but ultrafast recovery silicon diode (not Schottky); VF = 1.1 V @ 16 A, higher loss | Higher switching loss and EMI; suitable only where Schottky leakage is unacceptable | Choose only if reverse leakage <1 µA at 100°C is mandatory and efficiency is secondary |
Compared with VS-16CTQ030PBF and MUR1630CT, the SRA1630 offers AEC-Q101 qualification and balanced trade-offs between forward loss, thermal resistance, and leakage-making it optimal for automotive and high-reliability industrial rectification where both efficiency and ruggedness are required.

FAQ
What is the maximum junction temperature rating for the SRA1630?
The SRA1630 has a maximum junction temperature of +150°C, enabling reliable operation in high-ambient environments such as automotive engine compartments and sealed industrial enclosures. This rating applies to both standard and AEC-Q101-qualified (SRA1630H) versions and is validated per JEDEC JESD22-A108 thermal stress testing protocols.
Does the SRA1630 have AEC-Q101 qualification?
Yes-the SRA1630H variant is fully AEC-Q101 qualified, covering stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling. The standard SRA1630 (non-H) is not AEC-Q101 qualified; qualification status is encoded in the ordering code suffix 'H'.
What is the forward voltage drop of the SRA1630 at rated current?
The SRA1630 exhibits a typical forward voltage of 0.55 V at 16 A and 25°C junction temperature, measured under pulsed conditions (PW = 0.3 ms). This low VF directly reduces conduction losses and improves overall power stage efficiency in SMPS and DC-DC applications.
How is the cathode connected in the TO-220AC package of the SRA1630?
In the SRA1630 TO-220AC package, the metal tab is electrically connected to the cathode. Lead 2 is also a cathode terminal, allowing flexible PCB layout-either using the tab for heatsink conduction (with insulating washer) or using lead 2 for isolated cathode routing while keeping the tab floating or grounded via thermal pad only.
What packaging and reel options are available for the SRA1630?
The SRA1630 is supplied in TO-220AC package, packed 50 units per tube. Tape-and-reel packaging is not offered; all variants-including SRA1630 and SRA1630H-are tube-only. Tube labeling includes date code (YWW), factory code (F), and green compound indicator (G) per TSC marking standards.
