Product details
Overview
SA60H from Taiwan Semiconductor is a unidirectional AEC-Q101-qualified transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 500W peak pulse power at 10/1000μs, 60V working stand-off voltage (VWM), and clamps to ≤107V at 4.9A peak pulse current. It delivers low leakage (<1μA @ VWM), fast response (<1.0ps), and operates from –55°C to +175°C - ideal for automotive power rail and ECU input protection.
For engineers reviewing the SA60H datasheet, SA60H pinout, SA60H application, or SA60H equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity, 60V VWM tolerance, 107V clamping voltage at 4.9A, and DO-15 mechanical compatibility with high-reliability automotive PCB layouts.
Technical Context
The SA60H employs a silicon avalanche junction structure optimized for high-energy transients, with breakdown voltage (VBR) specified at 66.7–81.5V under 1mA test current. Its unidirectional configuration ensures cathode-anode conduction only during reverse overvoltage events, eliminating forward conduction path concerns in DC-biased rails.
Thermal design is supported by a 175°C maximum junction temperature and 3W steady-state power dissipation (at TL = 75°C on 10×10 mm copper pads). The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements - critical for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous DC or RMS voltage the device blocks without significant leakage; sets upper limit for protected circuit operating voltage. |
| VBR min/max | 66.7 V / 81.5 V - Breakdown occurs within this range at 1 mA; defines minimum overvoltage threshold before clamping activates. |
| VC @ IPPM | 107 V at 4.9 A - Clamping voltage during 10/1000μs surge; determines maximum stress imposed on downstream ICs during transient events. |
| PPK | 500 W - Peak pulse power handling per single non-repetitive 10/1000μs waveform; validates robustness against ISO 7637-2 Pulse 1/2a/5a surges. |
| IR @ VWM | <1 μA - Reverse leakage at 60 V; ensures negligible standby current draw in battery-sensitive automotive modules. |
| TJ max | +175 °C - Maximum junction temperature; enables placement near hot components (e.g., power MOSFETs, engine control units) without derating. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or low-side return path; completes clamping loop when cathode is at higher potential. |
| Cathode | Transient sensing & clamping terminal | Connected to protected line (e.g., 12V rail); avalanche breakdown initiates here during overvoltage, shunting surge to ground via anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias HAST, and mechanical shock - required for ECU, body control, and ADAS module deployment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A | Bidirectional configuration; same VWM (60V), but symmetric clamping (107V in both directions); slightly lower PPK (400W). | Required where bidirectional surges occur (e.g., AC-coupled data lines); unsuitable for DC-biased rails needing unidirectional blocking. | Select SMAJ60A only if system-level transients lack polarity definition; SA60H provides superior DC blocking and higher surge margin. |
| 1.5KE60A | Higher clamping voltage (108V vs. 107V), same VWM (60V), but larger DO-201AD package and no AEC-Q101 qualification. | Limited to industrial/commercial use; not approved for automotive under-hood deployment due to missing qualification and thermal derating profile. | Choose 1.5KE60A only for cost-sensitive non-automotive designs; SA60H offers guaranteed automotive reliability and tighter thermal specs. |
Compared with SMAJ60A and 1.5KE60A, the SA60H uniquely combines AEC-Q101 qualification, unidirectional polarity, 500W surge rating, and DO-15 footprint - making it the only option qualified for production automotive power rail protection without layout or qualification revalidation.

FAQ
What does the "H" suffix signify in SA60H?
The "H" suffix in SA60H indicates full AEC-Q101 qualification - verified through temperature cycling, highly accelerated stress testing (HAST), and mechanical shock validation. This certification confirms SA60H meets automotive reliability standards for under-hood deployment, unlike non-H variants such as SA60 or SA60A which lack formal qualification documentation.
Is SA60H unidirectional or bidirectional?
SA60H is a unidirectional TVS diode, as confirmed by its cathode band marking, asymmetric electrical characteristics (VBR defined only for reverse bias), and absence of bidirectional parameters in its datasheet table. It conducts only when cathode voltage exceeds anode voltage by ≥66.7V - essential for DC power rail protection where forward conduction must be avoided.
What is the clamping voltage of SA60H at its rated surge current?
The clamping voltage of SA60H is 107 V at 4.9 A peak pulse current (IPPM), measured under the standard 10/1000μs waveform. This value represents the maximum voltage seen by downstream circuitry during a worst-case transient, directly determining whether protected ICs remain within their absolute maximum ratings.
Can SA60H replace SA60A in an existing design?
SA60H can replace SA60A electrically and mechanically - both share identical VWM (60V), VBR range (66.7–81.5V), DO-204AC package, and pinout. However, SA60H adds AEC-Q101 qualification, making it suitable for automotive production where SA60A is limited to commercial/industrial use; no PCB changes are needed for drop-in substitution.
What is the maximum junction temperature rating for SA60H?
The maximum junction temperature (TJ max) for SA60H is +175°C, validated per AEC-Q101 thermal test conditions. This allows direct mounting near heat sources such as power inductors or MOSFETs in automotive modules, with derating curves provided in Figure 2 of the official datasheet for ambient temperatures above 25°C.
