Product details
Overview
SS13MHRSG from Taiwan Semiconductor is a 1A, 30V Schottky barrier surface-mount rectifier in Micro SMA package, featuring 0.45V forward voltage at 0.5A/25°C, 25A surge rating, and 150°C max junction temperature. It serves as primary output rectifier in compact AC-DC adapters and DC-DC converters where low conduction loss and thin profile are critical.
For engineers reviewing the SS13MHRSG datasheet, SS13MHRSG pinout, SS13MHRSG application, or SS13MHRSG equivalent, key selection factors include its 30V VRRM, 0.68mm height constraint, 50µA reverse leakage at 25°C, thermal resistance (RθJL = 30°C/W), and Micro SMA polarity marking via cathode band.
Technical Context
This Schottky rectifier uses a single-die construction with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Its low VF enables high efficiency in 5–24V output SMPS stages operating up to 150°C junction temperature.
The device exhibits 50pF junction capacitance at 1MHz/4V and 10mA reverse leakage at 125°C - parameters directly impacting EMI filtering design and high-temperature reliability in space-constrained power supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS13FL from ON Semiconductor | VRRM = 30V, VF = 0.52V @ 1A/25°C, same Micro SMA package | Higher forward voltage increases conduction loss by ~15% at full load | Prefer SS13MHRSG when thermal margin is constrained or efficiency >91% required |
| SB130 from Diodes Inc. | VRRM = 30V, VF = 0.55V @ 1A/25°C, SMA package (not Micro SMA) | 0.9mm height and larger footprint require PCB layout revision | Choose SS13MHRSG for space-constrained designs needing 0.68mm height and automated placement compatibility |
Compared with SS13FL and SB130, SS13MHRSG delivers the lowest forward voltage in its class and the smallest form factor, making it optimal for thermally dense, height-limited power supplies where efficiency and board area are co-prioritized.

FAQ
What is the maximum repetitive peak reverse voltage rating for SS13MHRSG?
The SS13MHRSG has a maximum repetitive peak reverse voltage (VRRM) of 30 V, verified per Taiwan Semiconductor's O2103 datasheet. This rating defines the highest reverse-biased voltage the device can block continuously without breakdown. Engineers must ensure system-level reverse transients do not exceed this value, especially in flyback or forward converter topologies with leakage spike margins.
Does SS13MHRSG have a halogen-free construction?
Yes, SS13MHRSG is halogen-free in accordance with IEC 61249-2-21, as confirmed in the official Taiwan Semiconductor documentation. This compliance supports environmental requirements for consumer electronics sold in EU, Japan, and other regulated markets, and eliminates brominated flame retardants from the molding compound without compromising UL 94V-0 flammability performance.
What is the forward voltage of SS13MHRSG at 1.0A and 25°C?
The forward voltage (VF) of SS13MHRSG is 0.52 V at 1.0 A and 25°C, per the Electrical Specifications table in the O2103 datasheet. This value reflects typical conduction loss under nominal conditions and is critical for calculating power dissipation (PLOSS = IF × VF) and thermal design margin in real-world applications.
Is SS13MHRSG compatible with lead-free reflow soldering processes?
Yes, SS13MHRSG features matte tin-plated leads qualified per J-STD-002 for solderability, supporting both lead-free SAC305 and traditional SnPb reflow profiles. Its moisture sensitivity level (MSL) is Level 1, meaning no dry-pack or baking is required prior to assembly - reducing manufacturing overhead and improving first-pass yield in high-volume SMT lines.
What package type does SS13MHRSG use, and how is polarity indicated?
SS13MHRSG uses the Micro SMA surface-mount package with a typical height of 0.68 mm. Polarity is indicated by a visible cathode band on the device body, aligning with the cathode terminal in the standard Micro SMA pinout. This marking is essential for correct orientation during automated placement and visual inspection to prevent reverse-bias failure in circuit operation.
