Product details
Overview
SS13HR3G 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 rating up to +125°C. It serves as a low-loss freewheeling or output rectifier in compact DC/DC converters and AC/DC adapters.
For engineers reviewing the SS13HR3G datasheet, SS13HR3G pinout, SS13HR3G application, or SS13HR3G equivalent, key selection criteria include forward voltage at operating temperature, reverse leakage at rated VRRM, thermal resistance (RθJL = 28°C/W), and compatibility with automated SMT placement on high-density PCBs.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring for overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its low VF and high IFSM support efficient power conversion in space-constrained, thermally demanding applications.
Rated for 30V repetitive peak reverse voltage (VRRM) and 21V RMS reverse voltage, it exhibits 200μA max reverse current at 25°C and 6mA at 100°C - enabling stable operation across industrial ambient temperature ranges without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - maximum non-repetitive reverse blocking capability, defining safe operating voltage margin in SMPS output stages |
| IF | 1 A continuous - steady-state forward current rating at case temperature ≤ 75°C, suitable for low-power adapter outputs |
| VF @ 1A, 25°C | 0.50 V max - low conduction loss enabling >92% efficiency in 5–12V DC/DC buck converters |
| IFSM | 40 A - withstands inrush and transient surges during hot-plug or load dump events |
| RθJL | 28 °C/W - enables direct heat transfer to PCB copper, supporting 1A operation without external heatsink |
| TJ max | +125 °C - junction temperature limit compatible with standard FR-4 PCBs and reflow profiles |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode indicated by molded band; lead-free, halogen-free, RoHS-compliant molding compound meeting UL 94V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter or transformer secondary center-tap) |
| Cathode | Forward current exit / reverse voltage reference | Marked by band; tied to output rail or ground return path; defines polarity-sensitive placement in layout |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents premature edge breakdown under high dv/dt or transient overvoltage, improving reliability in noisy SMPS environments |
| Moisture sensitivity level 1 | No dry-pack or baking required before reflow - simplifies manufacturing and reduces process cost |
| High surge current capability | 40A IFSM supports robustness against line transients and capacitor charging spikes without derating |
| Low thermal resistance | RθJL = 28°C/W allows full 1A current handling with minimal temperature rise on 1-oz copper pads |
Applications
| Switching Mode Power Supply (SMPS) | AC/DC Adapter |
|---|---|
Use Scenario: Secondary-side rectification in 5–24V isolated flyback or forward converters. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; defines output voltage ripple and efficiency. Use Value: 0.50V VF minimizes conduction loss, directly increasing light-load efficiency by ~3–5% versus standard PN diodes. | Use Scenario: Output rectification in compact wall-mounted USB-C or laptop adapters. IC Role / Device Role / Timing Role: Unidirectional current path converting transformer AC to regulated DC; operates continuously at 1A average current. Use Value: DO-214AC footprint enables high-density layout; moisture level 1 eliminates pre-bake, accelerating production throughput. |
| DC/DC Converter | Monitor Power Supply |
Use Scenario: Synchronous rectifier replacement in non-isolated buck converters for FPGA or SoC core rails. IC Role / Device Role / Timing Role: Low-loss freewheeling element during high-side switch off-phase; critical for maintaining regulation under dynamic load steps. Use Value: 40A IFSM tolerates large inductor current overshoot during startup or fault recovery without degradation. | Use Scenario: Standby and main rail rectification in LCD monitor auxiliary power supplies. IC Role / Device Role / Timing Role: Input rectifier for 12V/24V internal SMPS; exposed to repeated thermal cycling and long-term bias stress. Use Value: 125°C TJ max and <200μA IR at 25°C ensure stable performance over 10+ year field life with minimal parameter drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS13H-E3/5AT (Vishay) | VF = 0.52V max @ 1A/25°C; same DO-214AC package; RθJA = 90°C/W vs. 88°C/W | Identical VRRM and IF; slightly higher VF reduces efficiency margin in thermally constrained designs | Preferred where Vishay's qualification history in automotive-grade monitors is required |
| SB130-TB (ON Semiconductor) | VRRM = 30V; VF = 0.55V max @ 1A/25°C; RθJL = 30°C/W; JEDEC DO-214AC compliant but different marking and tape/reel packaging | Same electrical class but higher thermal resistance requires larger pad area for equivalent thermal performance | Selected when ON Semi's supply chain continuity or dual-sourcing policy mandates second-source availability |
Compared with SS13HR3G, SS13H-E3/5AT offers near-identical performance with minor VF trade-off, while SB130-TB provides functional equivalence at the cost of slightly reduced thermal efficiency - both require no PCB redesign but may need layout review for thermal pad optimization.

FAQ
What is the maximum junction temperature rating for SS13HR3G?
The SS13HR3G has a maximum junction temperature (TJ) rating of +125°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet R2305. This rating applies under continuous DC operation with proper PCB thermal design and ensures reliable long-term performance in industrial ambient conditions up to +85°C. The SS13HR3G must not be operated beyond this limit to avoid irreversible degradation.
Does SS13HR3G have a halogen-free and RoHS-compliant construction?
Yes, SS13HR3G is explicitly stated as halogen-free and RoHS-compliant in the manufacturer's documentation (Version R2305). The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. These attributes are confirmed in the "Features" and "Mechanical Data" sections, making SS13HR3G suitable for environmentally regulated consumer and industrial end equipment.
What is the forward voltage of SS13HR3G at 1A and 100°C junction temperature?
The forward voltage (VF) of SS13HR3G is 0.40 V maximum at 1A and 100°C junction temperature, as specified in the "Electrical Specifications" table of the R2305 datasheet. This low VF at elevated temperature confirms stable conduction behavior under thermal stress, supporting consistent efficiency in high-ambient applications such as enclosed power adapters or LED drivers.
Is SS13HR3G suitable for automated SMT placement?
Yes, SS13HR3G is optimized for automated surface-mount placement, as highlighted in its "Features" list. Its DO-214AC (SMA) package, moisture sensitivity level 1 (per J-STD-020), and matte tin-plated leads ensure compatibility with standard reflow profiles and pick-and-place equipment without special handling or baking requirements - reducing manufacturing overhead and yield risk.
What is the peak forward surge current rating for SS13HR3G?
The SS13HR3G is rated for a peak forward surge current (IFSM) of 40 A, measured using an 8.3 ms single half-sine wave superimposed on rated load, per the Absolute Maximum Ratings table. This rating validates its ability to survive inrush currents during power-up, capacitor charging, and short-duration overload events typical in DC/DC and adapter applications.
