Product details
Overview
SA10H from Taiwan Semiconductor is a unidirectional 500W transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, with 11.1–13.6V breakdown voltage (VBR), 10V working stand-off voltage (VWM), and 18.8V maximum clamping voltage (VC) at 27A peak pulse current - designed for automotive-grade ESD and load-dump protection in power supply rails and signal lines.
For engineers reviewing the SA10H datasheet, SA10H pinout, SA10H application, or SA10H equivalent, this AEC-Q101 qualified TVS offers verified surge immunity per IEC 61000-4-2/4-4/4-5, low leakage (<1μA @ 10V), sub-1ps response time, and robust 175°C junction operation - critical for infotainment, body control, and ADAS subsystems requiring high-reliability overvoltage clamping.
Technical Context
The SA10H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its VBR range (11.1–13.6V @ 1mA test current), entering low-impedance clamping mode to limit transients to ≤18.8V at 27A (10/1000μs waveform). Its silicon p-n junction structure enables fast turn-on with typical response <1.0ps from 0V to VBR.
Designed for automotive environments, SA10H meets AEC-Q101 stress requirements including temperature cycling, humidity bias, and mechanical shock. It sustains 70A non-repetitive forward surge (8.3ms half-sine) and operates across –55°C to +175°C junction temperature, with thermal derating above 25°C ambient per Fig.2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before leakage rises significantly; sets safe margin below system rail (e.g., 12V automotive). |
| VBR min/max | 11.1 / 13.6 V @ 1 mA - Confirmed breakdown threshold range; ensures reliable triggering without premature conduction. |
| VC @ IPPM | 18.8 V @ 27 A - Clamped voltage during 500W transient; defines worst-case overvoltage seen by protected IC. |
| IPPM | 27 A - Peak pulse current capability at 10/1000μs waveform; supports ISO 7637-2 Pulse 1/2/5a compliance testing. |
| PPK | 500 W - Peak pulse power rating; validates energy absorption for 1ms surges in automotive load-dump scenarios. |
| TJ max | +175 °C - Maximum junction temperature; enables under-hood deployment without thermal derating penalties. |
| IR @ VWM | <1 μA - Reverse leakage at rated stand-off voltage; minimizes standby power loss in always-on circuits. |
Pinout & Package
SA10H uses the DO-204AC (DO-15) axial-leaded package with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance. Molding compound complies with UL 94V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current path / Ground reference | Connected to system ground or low-side return; conducts during forward surge events (e.g., reverse battery protection). |
| Cathode | Clamping node / High-side connection | Connected to protected line (e.g., 12V rail); sinks transient current into ground when VREV > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use per stress test requirements - enables drop-in deployment in Tier 1 ECUs without requalification. |
| Sub-1ps response time | Enables clamping before ESD pulses (IEC 61000-4-2) propagate into sensitive analog or digital inputs. |
| Low clamping ratio (VC/VBR ≈ 1.5) | Minimizes overvoltage overshoot during transients - critical for protecting 3.3V/5V logic interfaces downstream of protection. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS directives - supports green manufacturing and export compliance. |
| 175°C junction rating | Supports placement near heat sources (e.g., power converters) without thermal derating in engine compartment applications. |
Applications
| Automotive Power Rail Protection | Infotainment System ESD Guarding |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Unidirectional, 10V VWM, 11.1–12.3V VBR, 18.8V VC @ 27.5A, DO-214AC package | Smaller SMD footprint (vs. axial DO-15); lower thermal mass limits sustained surge duty cycle | Select SMAJ10A for space-constrained PCB layouts where reflow assembly is preferred and thermal cycling is moderate. |
| 1N6105A | Unidirectional, 10V VWM, 11.1–12.3V VBR, 18.8V VC @ 27A, DO-204AC package, no AEC-Q101 qualification | Lacks automotive qualification; same mechanical form factor but not validated for automotive stress profiles | Select 1N6105A only for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated. |
Compared with SMAJ10A and 1N6105A, SA10H uniquely combines AEC-Q101 qualification, DO-204AC axial lead compatibility, and identical electrical specs - making it the sole choice for production automotive designs requiring traceable qualification and through-hole assembly.

FAQ
What is the AEC-Q101 qualification status of SA10H?
The SA10H is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H" and datasheet Version L2105. This includes full stress testing for temperature cycling, high-temperature operating life, unbiased high-humidity storage, and mechanical shock - confirming suitability for automotive powertrain and chassis applications.
Does SA10H support bidirectional transient suppression?
No, SA10H is a unidirectional TVS diode. Its cathode band marking and electrical specifications (e.g., VF = 3.5V @ 35A) confirm asymmetric behavior. For bidirectional protection, TSC offers SA10CA (with "CA" suffix) - which has identical VWM and VBR in both directions.
What is the maximum clamping voltage of SA10H under standard test conditions?
The maximum clamping voltage (VC) of SA10H is 18.8 V at 27 A peak pulse current (10/1000μs waveform), as specified in the "MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS" table. This value is guaranteed across the full operating temperature range (–55°C to +175°C).
Can SA10H be used in place of SA10 or SA10A?
SA10H is functionally identical to SA10A in electrical parameters (VBR: 11.1–12.3V, VC: 17.0V @ 30A) but adds AEC-Q101 qualification and tighter process controls. SA10 (non-A, non-H) lacks automotive qualification and has higher VC (18.8V @ 27A). SA10H replaces SA10A directly in automotive designs; SA10 is not recommended for AEC-Q101 applications.
What packaging options are available for SA10H?
SA10H is supplied in DO-204AC (DO-15) package with two packing options: 3,500 pieces per tape-and-reel (standard for automated assembly) and 1,500 pieces per ammo box (for manual or low-volume prototyping). Both options retain full AEC-Q101 traceability and date-code marking (YWW format).
