Product details
Overview
SA130CH from Taiwan Semiconductor is a unidirectional AEC-Q101-qualified transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 130 V working stand-off voltage (VWM), 144–176 V breakdown voltage (VBR @ 1 mA), and 500 W peak pulse power (10/1000 µs). It delivers 2.2 A peak pulse current (IPPM) with 230 V clamping voltage (VC) and operates from –55 °C to +175 °C - designed for automotive ESD and load-dump protection in powertrain control modules.
For engineers reviewing the SA130CH datasheet, SA130CH pinout, SA130CH application, or SA130CH equivalent, this page provides verified electrical parameters, AEC-Q101 qualification status, clamping performance at rated surge, thermal derating behavior, and direct alternatives for automotive-grade TVS selection.
Technical Context
The SA130CH uses silicon avalanche junction technology to provide fast, repeatable overvoltage clamping. Its unidirectional polarity enables integration into DC power rails where reverse conduction must be blocked - critical for 12 V/24 V automotive systems with battery-referenced loads.
It meets IEC 61000-4-2 (±30 kV contact), IEC 61000-4-4 (±4 kV), and ISO 7637-2 Pulse 1/2a/3a/5a requirements when applied with appropriate layout and series impedance. The 1.0 ps response time (0 V → VBR) ensures sub-nanosecond turn-on before sensitive ICs experience overstress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous DC or RMS voltage the device blocks without clamping; sets minimum system operating margin before protection activates. |
| VBR @ 1 mA | 144–176 V - Measured breakdown range at 1 mA test current; defines guaranteed turn-on threshold under standardized conditions. |
| VC @ IPPM | 230 V - Clamping voltage at 2.2 A peak pulse current (10/1000 µs); determines maximum voltage seen by protected circuit during surge. |
| PPK | 500 W - Peak pulse power rating per 10/1000 µs waveform; validates capability to absorb automotive load-dump transients (ISO 7637-2 Pulse 5a). |
| TJ max | +175 °C - Maximum junction temperature; supports under-hood placement in engine control units without thermal derating penalties. |
| IR @ VWM | <1 µA - Reverse leakage at 130 V; ensures negligible standby current drain in always-on vehicle subsystems. |
| AEC-Q101 | Qualified - Validated for automotive use per stress test requirements including HTOL, TCT, HTRB, and ESD; required for powertrain and chassis applications. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with UL 94V-0 flammability rating. Cathode indicated by band marking; anode and cathode leads are pure tin-plated for J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Input/Line side of protected DC rail | Connected to power source (e.g., battery+); conducts forward during fault only if used in bidirectional configuration (not applicable to SA130CH). |
| Cathode (banded end) | Clamp reference / ground return | Connected to system ground or low-impedance return path; carries full surge current during clamping event. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ130A | Same DO-214AC package; VBR = 144–176 V, VC = 230 V, PPK = 400 W (lower than SA130CH's 500 W). | Rated for 400 W only - insufficient for full ISO 7637-2 Pulse 5a compliance at higher source impedances. | Select SA130CH when 500 W surge handling is mandatory; SMAJ130A may require parallel staging for equivalent energy absorption. |
| ON Semiconductor 1.5SMC130A | DO-214AB package; VBR = 144–176 V, VC = 230 V, PPK = 1500 W - higher power but larger footprint and different thermal profile. | Requires PCB redesign due to larger SMC package; better suited for non-space-constrained industrial power supplies. | Choose SA130CH for DO-15 footprint compatibility and AEC-Q101 validation; 1.5SMC130A fits where board space allows and >500 W headroom is needed. |
Compared with SMAJ130A and 1.5SMC130A, SA130CH uniquely combines AEC-Q101 qualification, DO-15 form factor, and full 500 W 10/1000 µs rating - making it optimal for space-limited automotive modules requiring certified reliability without layout change.

FAQ
What is the AEC-Q101 qualification status of SA130CH?
The SA130CH is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirmed in the SA Series datasheet Version L2105. This includes full stress testing for high-temperature operating life, temperature cycling, highly accelerated stress test, and ESD - validating its suitability for automotive powertrain and chassis applications where functional safety is required.
Does SA130CH support bidirectional transient suppression?
No, SA130CH is a unidirectional TVS diode - its cathode band marking indicates polarity-sensitive installation. Bidirectional operation requires the "CA" suffix variant (e.g., SA130CA), which has symmetrical breakdown in both directions. Using SA130CH in reverse-biased AC applications will result in forward conduction and failure.
What is the maximum clamping voltage of SA130CH under standard test conditions?
The maximum clamping voltage (VC) of SA130CH is 230 V, measured at 2.2 A peak pulse current (IPPM) using the 10/1000 µs waveform. This value is guaranteed across temperature and production lot, and defines the upper voltage limit imposed on protected circuits during worst-case surge events.
How does SA130CH compare to SA130A in terms of electrical performance?
SA130CH and SA130A share identical VWM (130 V), VBR (144–176 V), and VC (230 V), but SA130CH adds AEC-Q101 qualification and uses green compound molding (per marking diagram). SA130A lacks automotive qualification and is intended for commercial/industrial use only - SA130CH is the correct choice for automotive Tier 1 BOMs.
What is the thermal derating behavior of SA130CH above 25°C ambient?
SA130CH follows the standard pulse derating curve in Figure 2 of the datasheet: peak pulse power drops linearly from 100% at 25°C to ~50% at 100°C ambient, and to ~25% at 150°C. Derating is based on junction temperature; effective thermal design requires ≥10 × 10 mm copper pads per lead to maintain safe TJ under repeated surges.
