Product details
Overview
SS13 R3G from Taiwan Semiconductor is a 1A, 30V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, featuring 0.50V forward voltage at 1A/25°C, 40A peak surge current, and junction temperature up to +150°C. It serves as a low-loss freewheeling or output rectifier in compact DC/DC converters and AC/DC adapters.
For engineers reviewing the SS13 R3G datasheet, SS13 R3G pinout, SS13 R3G application, or SS13 R3G equivalent, key selection criteria include its 30V VRRM, low VF at high temperature, moisture sensitivity level 1 compliance, RoHS/halogen-free status, and suitability for automated SMT assembly in space-constrained power supplies.
Technical Context
The SS13 R3G implements a single-die Schottky junction optimized for fast switching and minimal conduction loss. Its 10,000 V/µs dV/dt rating supports reliable operation in high-frequency SMPS topologies, while the guard ring structure provides overvoltage robustness without compromising leakage performance.
Thermal design is enabled by RθJL = 28°C/W and RθJA = 88°C/W, allowing 1A continuous operation with moderate PCB copper area. Reverse leakage remains ≤200 µA at 25°C and ≤6 mA at 100°C under rated 30V reverse bias.
Key Specifications

| VF @ 1A, 25°C | 0.50 V - Low conduction loss enabling >92% efficiency in 5–12V buck converters |
| IFSM | 40 A - Peak surge capability handles inrush and transient overload without failure |
| TJ max | +150°C - Extended junction temperature rating allows operation in sealed or high-ambient industrial enclosures |
| RθJL | 28°C/W - Enables direct thermal transfer to PCB copper pour for passive cooling in cost-sensitive designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SS13H | VF = 0.52V @ 1A/25°C; same DO-214AC package; MSL Level 1 | Identical electrical envelope but slightly higher forward drop increases conduction loss by ~4 mW at 1A | Preferred where ON Semi supply chain alignment is required; no layout change needed |
| Vishay VS-1SS3 | VRRM = 30V; IF = 1A; VF = 0.55V @ 1A/25°C; RθJA = 90°C/W | Higher thermal resistance limits ambient operating range by ~5°C at full load | Suitable for lower-power applications (<800mW dissipation); verified compatibility in existing SMA footprints |
Compared with SS13 R3G, SS13H offers identical form factor with marginally higher VF, while VS-1SS3 trades 0.05V higher forward drop and reduced thermal performance for broader global distribution-both require no PCB revision but may impact thermal margin in sealed enclosures.

FAQ
What is the maximum junction temperature rating for SS13 R3G?
The SS13 R3G has a maximum junction temperature (TJ) rating of +150°C, confirmed in the Absolute Maximum Ratings table. This allows sustained 1A operation in ambient temperatures up to +85°C with appropriate PCB copper area, making SS13 R3G suitable for enclosed industrial power supplies where thermal headroom is constrained.
Does SS13 R3G meet lead-free and RoHS requirements?
Yes, SS13 R3G is RoHS compliant and halogen-free, as explicitly stated in the FEATURES section. Its matte tin-plated leads are solderable per J-STD-002, and the molding compound meets UL 94V-0 flammability rating-fully satisfying WEEE and China RoHS II regulatory mandates for commercial and industrial end equipment.
What is the forward voltage of SS13 R3G at elevated temperature?
At 1A and +100°C junction temperature, SS13 R3G exhibits a typical forward voltage of 0.40V, per the Electrical Specifications table. This 20% reduction versus its 25°C value (0.50V) improves efficiency stability across operating temperature ranges, a key advantage over silicon diodes whose VF increases with temperature.
Is SS13 R3G suitable for high-frequency switching applications?
Yes, SS13 R3G supports high-frequency operation due to its Schottky architecture with negligible reverse recovery time and 10,000 V/µs critical dV/dt rating. These characteristics prevent false triggering in QR flyback or active clamp forward converters operating above 100 kHz, confirming SS13 R3G's suitability for modern high-density SMPS designs.
What packaging format is used for SS13 R3G?
SS13 R3G is supplied in 7,500-piece tape-and-reel packaging per the Ordering Information table, compatible with standard 8mm-width SMT feeders. The DO-214AC (SMA) case uses matte tin-plated leads and meets JESD201 Class 2 whisker resistance, ensuring reliable pick-and-place yield and solder joint integrity in high-volume manufacturing.
