Taiwan Semiconductor Corporation SA130

Overview

SA130 from Taiwan Semiconductor is a unidirectional 500W transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, with 130V working stand-off voltage (VWM), 144–176V breakdown voltage (VBR @ 1mA), and 230V clamping voltage (VC) at 2.2A peak pulse current. It delivers fast response (<1.0ps), low leakage (<1μA @ 130V), and AEC-Q101 qualification for automotive-grade surge protection.

For engineers reviewing the SA130 datasheet, SA130 pinout, SA130 application, or SA130 equivalent, this page provides verified electrical parameters, mechanical packaging details, real-world use cases in automotive and industrial systems, and validated alternative parts for ESD and inductive switching transient suppression.

Technical Context

The SA130 operates as a unidirectional avalanche diode, designed to clamp high-energy transients (per 10/1000μs waveform) before they damage downstream ICs or power stages. Its VBR range (144–176V) ensures reliable triggering above 130V operating voltage while maintaining tight tolerance and low temperature coefficient (175 mV/°C).

It features pure tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and meets JESD201 Class 2 whisker resistance. The device is rated for TJ = –55°C to +175°C and supports steady-state power dissipation of 3W at TL = 75°C on 10×10 mm copper pads.

FAQ

What is the maximum clamping voltage of SA130 under standard 10/1000μs surge conditions?

The SA130 has a maximum clamping voltage (VC) of 230 V when subjected to its rated peak pulse current of 2.2 A under the 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits experience no more than 230 V during transient events-critical for safeguarding 150V-rated downstream components in 24V automotive systems.

Is SA130 suitable for bidirectional transient protection?

No, SA130 is a unidirectional TVS diode intended for line-to-ground clamping in DC systems. For bidirectional protection (e.g., AC lines or data lines), the SA130A variant or dedicated bipolar parts like SA130CA must be used. The SA130 datasheet explicitly specifies polarity marking and unidirectional electrical characteristics, confirming its single-direction functionality.

Does SA130 meet AEC-Q101 reliability standards?

Yes, SA130 is AEC-Q101 qualified when ordered with the "H" suffix (e.g., SA130H). The base SA130 part shares identical electrical and thermal specifications but lacks formal automotive qualification documentation unless marked with H. Engineers deploying SA130 in automotive applications must specify SA130H to ensure full compliance with stress tests including HTGB, HTRB, and temperature cycling.

What is the thermal resistance junction-to-lead (RθJL) for SA130 in DO-15 package?

Taiwan Semiconductor does not publish RθJL for SA130 in the provided datasheet. However, based on DO-204AC (DO-15) industry norms and thermal derating curves (Fig.2), SA130 achieves 3 W steady-state power dissipation at TL = 75°C with 9.5 mm lead length. For precise thermal modeling, users should refer to TSC's application note AN-S001 or contact Aetrix for test-report-backed RθJL characterization data.

Can SA130 replace SA130A in a design without modification?

No-SA130 and SA130A differ in breakdown voltage tolerance: SA130 has VBR = 144–176 V (±11%), while SA130A has tighter VBR = 144–159 V (±5%). This affects clamping consistency under marginal overvoltage. SA130A also exhibits lower VC (209 V vs. 230 V) and higher IPPM (2.5 A vs. 2.2 A). Substitution requires validation of system-level surge margin and may necessitate layout or firmware adjustments.
