Product details
Overview
SA130H from Taiwan Semiconductor is a unidirectional AEC-Q101-qualified transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 130V working stand-off voltage, 144–176V breakdown voltage at 1mA, 2.2A peak pulse current, and 230V clamping voltage at IPPM - designed to protect automotive power rails and industrial control inputs against ISO 7637-2/IEC 61000-4-5 surges.
For engineers reviewing the SA130H datasheet, SA130H pinout, SA130H application, or SA130H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, clamping performance under 10/1000μs transients, thermal derating behavior, and direct alternatives with documented VWM/VBR/VC alignment - all specific to the SA130H variant.
Technical Context
The SA130H implements a silicon avalanche diode structure optimized for fast transient suppression in automotive 12V/24V systems. Its unidirectional polarity enables DC rail protection with cathode-anode orientation, and its 175°C maximum junction temperature supports under-hood deployment. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 molding compound requirements.
Clamping occurs within 1.0ps from 0V to VBR, delivering sub-nanosecond response to ESD and load-dump events. With <1μA reverse leakage at 130V and 230V VC at 2.2A IPPM, it maintains low standby loss while limiting surge energy dissipation to the protected IC's safe operating area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous DC or RMS voltage the device blocks without conduction; sets upper limit for protected circuit operating voltage. |
| VBR @ IT=1mA | 144–176 V - Breakdown voltage range where avalanche conduction begins; defines minimum overvoltage threshold before clamping activates. |
| VC @ IPPM=2.2A | 230 V - Clamped voltage during 10/1000μs surge; determines maximum stress imposed on downstream components during transient. |
| PPK | 500 W - Peak pulse power rating per 10/1000μs waveform; quantifies single-event surge energy absorption capability. |
| TJ MAX | 175 °C - Maximum allowable junction temperature; enables operation in high-ambient environments such as engine compartments. |
| IR @ VWM | <1 μA - Reverse leakage current at rated stand-off voltage; ensures minimal quiescent power loss and signal integrity in high-impedance circuits. |
| Package | DO-204AC (DO-15) - Industry-standard axial-leaded package with tin-plated leads compliant to J-STD-002; supports wave and reflow soldering. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Current entry point during forward conduction; connected to system ground or low-side reference in unidirectional TVS configuration | Enables low-VF path during positive transients when cathode is tied to protected line; defines directionality of protection. |
| Cathode (banded lead) | Transient voltage sensing node; connected to protected circuit node (e.g., 12V rail, CAN line, sensor input) | Acts as voltage reference for avalanche breakdown; clamps excess energy to ground when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias HAST, and mechanical shock - required for powertrain and body electronics. |
| 1.0ps response time (0V → VBR) | Ensures clamping activation before nanosecond-scale ESD pulses damage sensitive gate oxides in microcontrollers or transceivers. |
| 230V clamping at 2.2A IPPM | Provides defined overvoltage ceiling for 12V/24V systems during ISO 7637-2 Pulse 5a (load dump), preventing latch-up or burnout in downstream regulators. |
| UL 94V-0 flammability rating | Molding compound self-extinguishes within 10 seconds after flame removal - satisfies automotive safety standards for under-hood components. |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 for bromine/chlorine content & EU RoHS Directive 2011/65/EU - supports green manufacturing and end-of-life recycling. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Input Protection |
|---|---|

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, 130V VWM, but bidirectional; VBR min/max tighter (144–156V); VC = 209V @ 2.4A | Supports AC-coupled lines (e.g., CAN FD); less suitable for DC rail protection where unidirectional leakage matters | Choose SMAJ130A only if bipolar symmetry is required; SA130H offers lower IR and AEC-Q101 validation specific to unidirectional use cases. |
| ON Semiconductor 1.5SMC130AH | DO-214AB package (larger footprint); same VWM/VBR/VC specs; AEC-Q101 qualified; PPK = 1500W (higher surge margin) | Requires PCB layout change due to different pad geometry; suited for higher-energy transients beyond ISO 7637-2 | Select 1.5SMC130AH when surge energy exceeds 500W or when board space allows larger SMC package; SA130H fits legacy DO-15 footprints. |
Compared with SMAJ130A and 1.5SMC130AH, SA130H uniquely combines DO-204AC (DO-15) compatibility, AEC-Q101 certification for unidirectional operation, and <1μA leakage at 130V - making it optimal for space-constrained, low-quiescent automotive modules where polarity-aware clamping is critical.

FAQ
What is the AEC-Q101 qualification status of SA130H?
The SA130H is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirming full compliance with stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. This qualification applies directly to the SA130H part number and validates its suitability for automotive powertrain and chassis applications where reliability is mission-critical. SA130H must be specified with the "H" suffix to guarantee AEC-Q101 conformance.
Does SA130H support bidirectional transient suppression?
No, SA130H is a unidirectional TVS diode - its cathode band marking and electrical specifications (e.g., VF = 3.5V at 35A) confirm asymmetric conduction. It clamps only positive transients relative to ground. For bidirectional protection, the SA130AH variant (with "AH" suffix) must be used, which provides symmetrical VBR and VC in both polarities. Using SA130H on AC or differential lines risks failure during negative excursions.
What is the maximum clamping voltage of SA130H under standard test conditions?
The maximum clamping voltage (VC) of SA130H is 230 V, measured at peak pulse current (IPPM) of 2.2 A using the 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range and defines the absolute worst-case voltage imposed on protected circuitry during a standardized surge event. It is not a typical value - actual clamping may be lower depending on pulse shape and ambient temperature.
How does SA130H compare to SA130A in terms of electrical performance?
SA130H and SA130A share identical VWM (130 V), VBR (144–176 V), and VC (230 V) specifications, but SA130H adds AEC-Q101 qualification and enhanced process controls for automotive use. SA130A lacks the "H" suffix and is intended for industrial/commercial applications only. Both use DO-204AC packaging and have <1 μA IR at VWM, but only SA130H carries the full automotive reliability documentation and test reports required for Tier 1 supplier approvals.
What is the thermal derating behavior of SA130H above 25°C ambient?
SA130H's peak pulse power (PPK) derates linearly above TA = 25°C per Figure 2 in the datasheet: at 75°C ambient, PPK drops to ~350W; at 125°C, it falls to ~175W. This derating follows the standard 0.5% per °C slope typical for DO-204AC-packaged TVS diodes. Engineers must apply this curve when sizing SA130H for under-hood locations where ambient exceeds 70°C, ensuring the expected surge energy remains within the thermally adjusted PPK limit.
