Taiwan Semiconductor Corporation SA130CA

Overview

SA130CA from Taiwan Semiconductor is a bidirectional 130V transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 500W peak pulse power at 10/1000μs, with 230V clamping voltage at 2.2A peak pulse current and ≤1μA reverse leakage at 130V, designed for ESD and electrical fast transient protection in automotive lighting and power supply interfaces.

For engineers reviewing the SA130CA datasheet, SA130CA pinout, SA130CA application, or SA130CA equivalent, this page delivers verified clamping performance, AEC-Q101 qualification status, DO-15 mechanical dimensions, bidirectional surge response time (5.0ns), and direct replacement guidance for industrial and automotive board-level protection design.

Technical Context

The SA130CA is a silicon avalanche diode engineered for bidirectional transient suppression, operating symmetrically in both polarities with identical V_BR (144–176V) and V_C (230V) specifications. It meets IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) immunity requirements when deployed across DC rails or signal lines.

Its thermal design supports continuous operation from −55°C to +175°C junction temperature, with 3W steady-state power dissipation on 10×10 mm copper pads and 70A non-repetitive forward surge capability-enabling robust protection in inductive load switching environments such as automotive solenoid drivers and LED ballasts.

Manufacturer

Taiwan Semiconductor Company (TSC) is a vertically integrated Taiwanese semiconductor manufacturer specializing in discrete power devices, TVS diodes, rectifiers, and MOSFETs since 1979.

The SA Series was developed specifically for AEC-Q101-compliant board-level transient protection in automotive and industrial environments, emphasizing low clamping voltage, fast response, and high-temperature reliability.

FAQ

What is the clamping voltage of SA130CA at its rated peak pulse current?

The SA130CA has a maximum clamping voltage (V_C) of 230 V at 2.2 A peak pulse current (I_PPM) under 10/1000μs waveform conditions. This value is measured per ANSI/IEEE C62.35 and ensures downstream circuitry remains below destructive voltage thresholds during standardized surge events. The SA130CA maintains this clamping performance across its full operating temperature range of −55°C to +175°C.

Is SA130CA unidirectional or bidirectional, and how is polarity marked?

The SA130CA is a bidirectional TVS diode, meaning it provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional SA-series parts (e.g., SA130), the SA130CA has no cathode band marking-its DO-204AC package uses identical leads with no polarity designation. This design enables direct placement across AC-coupled lines or floating DC rails without orientation constraints.

Does SA130CA meet AEC-Q101 qualification, and what tests does that include?

Yes, the SA130CA is AEC-Q101 qualified (as indicated by the "H" suffix option in ordering code SA130CAH). This certification covers stress tests including temperature cycling (−40°C to +125°C, 1000 cycles), high-temperature reverse bias (1000 hrs at 125°C), mechanical shock (1500g), and solder heat resistance. TSC documentation confirms SA130CA passes all AEC-Q101 Rev H requirements for discrete semiconductors used in automotive electronic systems.

What is the maximum steady-state power dissipation for SA130CA, and under what conditions?

The SA130CA has a steady-state power dissipation (P_D) rating of 3 W when mounted on 10 × 10 mm copper pads per lead at terminal temperature (T_L) of 75°C. This rating applies only to continuous DC or low-frequency AC operation-not transient suppression. For pulsed operation, the device handles up to 500 W peak power per 10/1000μs waveform, with derating above 25°C ambient per Figure 2 in the SA Series datasheet.

How does SA130CA compare to SA130 in terms of electrical behavior and application use?

The SA130CA differs from SA130 in being bidirectional with symmetrical V_BR and clamping characteristics in both directions, whereas SA130 is unidirectional with cathode band marking and forward voltage drop (V_F = 3.5 V at 35 A). SA130CA is used where AC transients or reversible polarity must be suppressed (e.g., RS-485 buses), while SA130 suits DC rail protection with defined polarity. Both share identical V_WM (130 V), P_PK (500 W), and DO-204AC packaging.
