Product details
Overview
SS13MH from Taiwan Semiconductor is a 1A, 30V Schottky barrier surface-mount rectifier in Micro SMA package, featuring 0.52V forward voltage at 1.0A/25°C, 25A surge rating, and AEC-Q101 qualification for automotive use. It serves as a freewheeling or reverse-battery protection diode in DC/DC converters and car lighting systems.
For engineers reviewing the SS13MH datasheet, SS13MH pinout, SS13MH application, or SS13MH equivalent, key selection criteria include its 30V VRRM, low-profile 0.68mm height, J-STD-020 Level 1 moisture sensitivity, TJ max of 150°C, and Micro SMA terminal configuration with cathode band polarity marking.
Technical Context
The SS13MH operates as a single-die Schottky rectifier with metal–semiconductor junction enabling low VF and fast switching. Its thermal design supports RθJL = 30°C/W and RθJA = 125°C/W, enabling high-efficiency operation in space-constrained automotive power stages.
It delivers 5µA reverse leakage at 30V/25°C and 3mA at 125°C, with 50pF junction capacitance at 1MHz/4V - parameters critical for minimizing switching losses in high-frequency inverters and DC/DC converters up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in 12V/24V automotive systems. |
| IF | 1 A continuous - Rated average forward current; supports compact DC/DC output stage designs without forced cooling. |
| VF @ 1A, 25°C | 0.52 V - Low conduction loss enables >92% efficiency in 5–12V buck converters at full load. |
| IFSM | 25 A - Peak non-repetitive surge current handling; withstands inrush and fault transients in automotive lighting drivers. |
| TJ max | 150 °C - Maximum junction temperature; allows operation in under-hood environments with minimal derating. |
| CJ | 50 pF @ 1MHz, 4V - Low junction capacitance minimizes reverse recovery charge, reducing EMI in high-frequency switching. |
| RθJL | 30 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pour heat sinking without heatsink. |
Pinout & Package
Package: Micro SMA - Surface-mount, molded plastic case with matte tin-plated leads, 0.68mm typical height, UL 94V-0 rated, polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in buck converter); requires adequate copper area for thermal dissipation. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to higher-potential rail (e.g., input or output bus); determines reverse polarity protection direction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per stress test requirements. |
| 0.68mm profile height | Enables ultra-thin power modules and headlight PCBs where Z-height is constrained by mechanical housing. |
| Level 1 moisture sensitivity | Eliminates bake requirement prior to reflow; compatible with standard SMT assembly lines without special handling. |
| Halogen-free (IEC 61249-2-21) | Meets automotive OEM environmental compliance mandates for end-of-life material recovery and combustion safety. |
| Single-die configuration | Ensures consistent electrical characteristics across production lots; avoids mismatch issues found in dual-die parallel configurations. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semi NSS10100CT1G | 10A dual common-cathode, TO-277 package; higher current, larger footprint, no AEC-Q101 certification. | Suitable for higher-power 48V systems; not drop-in for Micro SMA layout or automotive qualification needs. | Select only if board redesign accommodates TO-277 and AEC-Q101 is not required. |
| Vishay VS-1EQH03-M3/84A | 1A, 30V, SMA package (not Micro SMA); 0.55V VF @ 1A; AEC-Q101 qualified; 0.9mm height. | Same voltage/current rating and qualification, but taller profile limits use in ultra-low-height assemblies. | Prefer SS13MH when Z-height ≤ 0.7mm is mandatory; otherwise, VS-1EQH03-M3/84A offers broader distributor availability. |
Compared with NSS10100CT1G and VS-1EQH03-M3/84A, the SS13MH uniquely combines AEC-Q101 qualification, Micro SMA footprint, and 0.68mm height - making it the only option for space- and compliance-constrained 12V automotive rectification where board thickness and qualification are non-negotiable.

FAQ
What is the maximum junction temperature rating for SS13MH?
The SS13MH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings in the official datasheet. This allows reliable operation in under-hood automotive environments where ambient temperatures exceed 85°C. Derating curves confirm usable current capacity down to 0.6A at 125°C ambient, ensuring robustness in SS13MH-based power designs.
Is SS13MH RoHS and halogen-free compliant?
Yes, SS13MH is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 - all documented compliance attributes directly applicable to SS13MH.
What does the marking code 'A' indicate on SS13MH devices?
The marking code 'A' on SS13MH devices identifies the specific voltage variant within the SS1xMH family, corresponding to the 30V VRRM rating. Per the ordering information table, 'A' = SS13MH, 'B' = SS14MH (40V), and 'C' = SS16MH (60V). This laser-marked identifier is visible on the cathode-band side of the Micro SMA package.
Can SS13MH be used in place of a standard PN rectifier in a 12V automotive circuit?
Yes, SS13MH can replace standard PN rectifiers in 12V automotive circuits, delivering lower forward voltage (0.52V vs. ~0.9V), faster switching, and reduced power loss. Its 30V VRRM provides sufficient margin for 12V systems with load dump transients. However, ensure layout accommodates Micro SMA footprint and verify reverse leakage tolerance in low-power sleep modes.
What is the moisture sensitivity level (MSL) of SS13MH and what does it mean for assembly?
SS13MH has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. This eliminates pre-bake steps in SMT assembly, simplifies logistics, and reduces risk of popcorning - a key advantage for high-volume automotive electronics manufacturing using SS13MH.
