Taiwan Semiconductor Corporation SA130AH

Overview

SA130AH from Taiwan Semiconductor is a unidirectional AEC-Q101-qualified transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, designed for automotive and industrial overvoltage protection. It features 130 V working stand-off voltage (VWM), 144–176 V breakdown voltage (VBR @ 1 mA), 2.2 A peak pulse current (IPPM), 230 V clamping voltage (VC) at IPPM, and 500 W surge capability per 10/1000 μs waveform.

For engineers reviewing the SA130AH datasheet, SA130AH pinout, SA130AH application, or SA130AH equivalent, key selection criteria include clamping performance under 10/1000 μs transients, AEC-Q101 qualification status, unidirectional polarity marking, DO-15 mechanical compatibility, and leakage current <1 μA at 130 V.

Technical Context

The SA130AH operates as a silicon avalanche diode with fast response time (<1.0 ps from 0 V to VBR), low dynamic impedance, and stable breakdown threshold across temperature. Its unidirectional configuration enables polarity-sensitive clamping on power rails or signal lines where reverse conduction must be blocked.

It meets IEC 61000-4-2 ESD (±30 kV contact), IEC 61000-4-4 EFT (±4 kV), and ISO 7637-2 pulse 1/2a/3a immunity requirements when applied with appropriate layout and series impedance. Junction temperature range is –55 °C to +175 °C, supporting under-hood automotive deployment.

FAQ

What is the AEC-Q101 qualification status of SA130AH?

The SA130AH is fully AEC-Q101 qualified per Version L2105 documentation. This includes testing for high-temperature reverse bias (HTRB), temperature cycling (TCT), and unbiased highly accelerated stress test (UHAST). The "H" suffix explicitly denotes AEC-Q101 compliance, making SA130AH suitable for automotive under-hood applications where reliability under thermal and electrical stress is critical.

Does SA130AH support bidirectional transient suppression?

No, SA130AH is a unidirectional TVS diode. Its cathode band marking indicates polarity-specific operation: it clamps positive transients on the cathode side relative to anode (ground). For bidirectional protection, SA130A (with "A" suffix) is the designated variant-SA130AH is strictly unidirectional and must be installed with correct orientation to avoid failure during negative transients.

What is the maximum clamping voltage of SA130AH under standard surge conditions?

The maximum clamping voltage (VC) of SA130AH is 230 V when subjected to its rated peak pulse current of 2.2 A under the 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and defines the upper voltage limit imposed on the protected circuit during worst-case surge events, ensuring downstream components remain within safe operating voltage margins.

How does the DO-204AC (DO-15) package of SA130AH impact thermal performance?

The DO-204AC (DO-15) axial package of SA130AH provides lower thermal resistance than surface-mount equivalents like DO-214AC due to longer lead paths acting as heat sinks. When mounted on 10 × 10 mm copper pads per terminal, its steady-state power dissipation is rated at 3 W at TL = 75 °C-enabling reliable operation in confined spaces where airflow is limited, such as sealed automotive junction boxes.

Is SA130AH halogen-free and RoHS compliant?

Yes, SA130AH is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all plating (pure tin) meets J-STD-002 solderability standards. These attributes support environmentally regulated manufacturing and end-of-life processing requirements for automotive and industrial OEMs.
