Product details
Overview
SS13LSH from Taiwan Semiconductor is a 1A, 30V Schottky barrier surface-mount rectifier in SOD-123HE package, featuring low forward voltage (0.50 V at 1.0 A, 25°C), high surge capability (30 A IFSM), AEC-Q101 qualification, and junction temperature up to +150°C - used in automotive lighting and DC/DC converter freewheeling paths.
For engineers reviewing the SS13LSH datasheet, SS13LSH pinout, SS13LSH application, or SS13LSH equivalent, key selection factors include its 30 V VRRM rating, 0.50 V VF at rated current, 73 pF junction capacitance, moisture sensitivity level 1 compliance, and SOD-123HE thermal performance (RθJA = 70°C/W).
Technical Context
The SS13LSH is a single-die, unidirectional Schottky rectifier optimized for low-loss, high-frequency switching in compact automotive and industrial power supplies. Its design targets minimal conduction loss and fast recovery with no minority-carrier storage delay.
It operates across -55°C to +150°C junction temperature range, supports 30 A non-repetitive surge current (8.3 ms half-sine), and maintains reverse leakage ≤400 µA at 25°C and ≤? mA at 125°C - consistent with its 30 V VRRM rating and 73 pF CJ at 1 MHz / 4 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - maximum repetitive reverse blocking voltage; defines safe operating limit in reverse-biased freewheeling or reverse-polarity protection circuits |
| IF | 1 A - continuous forward current rating; sets steady-state power delivery capacity without derating below 125°C ambient |
| VF @ 1.0 A | 0.50 V - forward voltage drop at full rated current; directly determines conduction loss (0.5 W typical) and thermal load |
| IFSM | 30 A - peak surge current handling; enables robustness against inductive kickback in DC/DC converters and motor drives |
| CJ | 73 pF - junction capacitance at 1 MHz / 4 V; impacts high-frequency switching efficiency and EMI in >100 kHz topologies |
| TJ max | +150°C - maximum junction temperature; allows operation in under-hood automotive environments without forced cooling |
| MSL | Level 1 - moisture sensitivity per J-STD-020; permits unlimited floor life and standard reflow without baking |
Pinout & Package
SOD-123HE surface-mount package: 2-terminal, single-anode/cathode configuration; cathode indicated by band; matte tin-plated leads; 0.021 g weight; profile <0.85 mm; UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit (e.g., switch node in buck converter); must handle full 1 A DC and 30 A surge |
| Cathode | Forward current exit / reverse-blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); polarity marking critical for reverse-battery protection integrity |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD - required for under-hood lighting and body control modules |
| Low VF (0.50 V @ 1 A) | Reduces conduction loss by ~20% vs. comparable 40 V Schottkys, improving efficiency in 12 V input DC/DC stages |
| SOD-123HE compact profile | Height <0.85 mm enables ultra-thin PCB designs in space-constrained automotive LED drivers and infotainment power rails |
| Junction-to-ambient RθJA = 70°C/W | Enables 1 A operation at 70°C ambient without heatsinking - verified via JEDEC-standard test board conditions |
| Moisture Sensitivity Level 1 | Eliminates pre-reflow baking step in SMT line, reducing process cost and preventing delamination risk during reflow |
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 | 1 A, 100 V VRRM; TO-277 package; VF = 0.55 V @ 1 A; RθJA = 90°C/W | Higher voltage rating but larger footprint and higher thermal resistance - less suitable for space-constrained 30 V systems | Select when 100 V blocking is required and board area allows TO-277; avoid if height <0.85 mm is mandatory |
| Vishay VSSAF130-M3/84A | 1 A, 30 V VRRM; SOD-123FL package; VF = 0.52 V @ 1 A; RθJA = 75°C/W; AEC-Q101 qualified | Nearly identical electrical specs but slightly higher VF and thermal resistance; same MSL Level 1 and automotive qualification | Drop-in alternative where SOD-123FL pad layout is already validated; verify cathode band orientation matches SS13LSH marking |
Compared with NSS10100CT1G and VSSAF130-M3/84A, the SS13LSH offers the lowest profile (<0.85 mm), tightest VF tolerance (0.50 V), and best thermal resistance (70°C/W) in the SOD-123HE form factor - making it optimal for ultra-thin automotive and portable power designs.

FAQ
What is the maximum junction temperature rating for SS13LSH?
The SS13LSH has a maximum junction temperature (TJ max) of +150°C, enabling reliable operation in under-hood automotive environments and high-ambient industrial settings without active cooling. This rating is validated per AEC-Q101 stress tests and applies across the full -55°C to +150°C operating range specified in the official Taiwan Semiconductor datasheet revision B2212.
Is SS13LSH pin-compatible with other parts in the SS1xLSH series?
Yes, all SS1xLSH variants - including SS12LSH, SS13LSH, SS14LSH, SS16LSH, SS110LSH, and SS115LSH - share identical SOD-123HE package dimensions, pinout (anode/cathode), and mounting footprint. The only differences are VRRM rating and associated electrical parameters; no PCB redesign is needed when upgrading within the series.
Does SS13LSH meet RoHS and halogen-free requirements?
Yes, SS13LSH is RoHS compliant and halogen-free per IEC 61249-2-21. These compliance statements are explicitly confirmed in the Taiwan Semiconductor datasheet (Version B2212), alongside J-STD-020 MSL Level 1 and AEC-Q101 qualification - supporting use in environmentally regulated automotive and industrial markets.
What is the forward voltage of SS13LSH at 0.5 A and 25°C?
The SS13LSH forward voltage at 0.5 A and 25°C is not explicitly published as a maximum or typical value in the datasheet; however, the curve data in Figure 4 shows VF ≈ 0.42–0.44 V under those conditions. At 1.0 A and 25°C, VF is specified as ≤0.50 V - a key parameter used for thermal and efficiency calculations in the SS13LSH design-in process.
Can SS13LSH be used in reverse-battery protection circuits?
Yes, SS13LSH is routinely deployed in reverse-battery protection due to its 30 V VRRM rating, low leakage (<400 µA at 25°C), and AEC-Q101 qualification. When placed anode-to-battery-negative, it blocks reverse polarity while passing forward current with only 0.50 V drop - preserving system efficiency in 12 V automotive subsystems where the SS13LSH serves as primary input protection.
