Product details
Overview
SA100CAH from Taiwan Semiconductor is a bidirectional 100V transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 500W peak pulse power at 10/1000μs, with 179V maximum clamping voltage at 2.9A peak pulse current and <1μA reverse leakage at 100V, designed for automotive-grade ESD and electrical fast transient protection in power supply rails and signal lines.
For engineers reviewing the SA100CAH datasheet, SA100CAH pinout, SA100CAH application, or SA100CAH equivalent, this AEC-Q101 qualified TVS offers verified bidirectional clamping performance, DO-15 mechanical compatibility, low-leakage operation above VWM, and validated surge immunity per IEC 61000-4-2/4-4/4-5 - critical for automotive body control modules, infotainment power inputs, and industrial sensor interfaces.
Technical Context
The SA100CAH is a silicon avalanche diode engineered for bidirectional transient suppression, with symmetrical breakdown characteristics (VBR min/max = 111V/136V at 1mA test current) enabling identical clamping behavior in both polarities. Its low dynamic impedance delivers consistent VC = 179V at IPPM = 2.9A under 10/1000μs waveform, supporting robust protection of 12V/24V automotive systems against load dump and ISO 7637-2 pulses.
Designed to operate across –55°C to +175°C junction temperature range, it features <1μA reverse leakage at rated 100V working stand-off voltage and a 135mV/°C temperature coefficient of VBR, ensuring stable clamping threshold over wide thermal conditions without external biasing or compensation circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous DC or RMS voltage the device blocks without conduction |
| VBR @ IT=1mA | 111–136 V - Breakdown initiates within this range, defining reliable turn-on threshold for transients |
| VC @ IPPM=2.9A | 179 V - Clamped voltage during 10/1000μs surge, limiting downstream stress to safe levels |
| PPK | 500 W - Peak pulse power handling capability per single non-repetitive 10/1000μs event |
| IR @ VWM | <1 μA - Negligible leakage ensures minimal standby power loss and signal integrity |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with UL 94V-0 molding and tin-plated leads |
| AEC-Q101 | Qualified - Validated for automotive applications including temperature cycling, humidity, and mechanical shock |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical glass-passivated body, cathode band marking absent (bidirectional), 0.400g weight, RoHS and halogen-free compliant, UL 94V-0 rated molding compound, pure tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (positive polarity) | One terminal of symmetrical avalanche junction; conducts when voltage exceeds +VBR |
| Cathode | Transient current entry (negative polarity) | Other terminal of symmetrical junction; conducts when voltage exceeds –VBR - no polarity marking required |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR (111–136V) and VC (179V) in both directions - eliminates need for polarity-aware placement |
| AEC-Q101 qualification | Validated for automotive underhood and cabin environments - supports PPAP and functional safety design requirements |
| Low clamping ratio | VC/VBR ≈ 1.4–1.6 - tight voltage margin between trigger and clamp enables precise system-level protection |
| Fast response time | <5.0 ns - sub-10ns turn-on ensures suppression before sensitive ICs experience overstress |
| High surge robustness | Withstands 500W 10/1000μs pulses and 70A 8.3ms half-sine surges - suitable for load dump and inductive switching events |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface 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 |
|---|---|---|---|
| SMAJ100CA | Same 100V VWM, 179V VC, but rated for 400W PPK and SMA package (surface-mount) | Requires PCB rework for SMT layout; lower thermal mass limits repetitive surge duty cycle | Select for space-constrained designs where DO-15 axial leads are incompatible |
| P6KE100CA | Same 100V VWM and bidirectional function, but 600W PPK rating and DO-15 package with higher VC = 187V | Higher clamping voltage increases risk of downstream overstress in low-margin systems | Select when higher single-pulse energy handling is prioritized over clamping precision |
Compared with SMAJ100CA and P6KE100CA, the SA100CAH provides optimal balance of AEC-Q101 compliance, 500W surge capacity, and tight 179V clamping in a through-hole DO-15 package - making it preferred for automotive production where qualification, reliability, and mechanical robustness are mandatory.

FAQ
What is the clamping voltage of SA100CAH at its rated peak pulse current?
The SA100CAH has a maximum clamping voltage (VC) of 179 V at a peak pulse current (IPPM) of 2.9 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry will not be exposed to voltages exceeding 179 V during a defined surge event, making SA100CAH suitable for protecting 100V-rated systems with margin.
Is SA100CAH unidirectional or bidirectional, and how is polarity indicated?
The SA100CAH is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients. It has no cathode band marking - the DO-204AC (DO-15) package is unpolarized, and either lead may serve as anode or cathode depending on applied voltage polarity. This eliminates orientation errors during manual or automated assembly.
Does SA100CAH meet automotive qualification standards?
Yes, SA100CAH is explicitly AEC-Q101 qualified, as confirmed by its "H" suffix in the ordering code and documentation in Taiwan Semiconductor's SA Series datasheet Version L2105. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - validating its suitability for automotive powertrain, chassis, and body electronics.
What is the maximum operating junction temperature for SA100CAH?
The SA100CAH has a maximum operating junction temperature (TJ MAX) of +175°C and a minimum of –55°C, enabling reliable operation in under-hood automotive environments and industrial settings with elevated ambient temperatures. Its thermal derating curve (Fig.2 in datasheet) defines allowable peak pulse power reduction above 25°C ambient, ensuring safe energy dissipation across the full range.
How does SA100CAH compare to SA100A in terms of breakdown voltage and application use?
The SA100CAH has a breakdown voltage range of 111–136 V at 1 mA, while SA100A (unidirectional, non-AEC-Q101) specifies 111–123 V. The "C" denotes bidirectional functionality and "H" confirms AEC-Q101 qualification - making SA100CAH appropriate for automotive dual-polarity protection, whereas SA100A is limited to single-direction use in commercial applications.
