Product details
Overview
SA60AH 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 fast response (<1.0ps), low leakage (<1μA @ 60V), and operates from –55°C to +175°C - used for automotive ECU and power supply rail protection.
For engineers reviewing the SA60AH datasheet, SA60AH pinout, SA60AH application, or SA60AH equivalent, key selection criteria include its AEC-Q101 qualification, 60V VWM / 66.7–81.5V VBR range, 107V clamping voltage at 4.9A, DO-15 mechanical compatibility, and suitability for 12V/24V automotive power line surge immunity per ISO 7637-2.
Technical Context
The SA60AH is a unidirectional silicon avalanche TVS diode designed for robust transient suppression on DC power rails. Its breakdown voltage (VBR) is specified at 66.7–81.5V with 1mA test current, and it maintains clamping performance up to 107V at 4.9A IPPM under 10/1000μs waveform.
It features low dynamic impedance, <1.0ps response time from 0V to VBR, and thermal stability supported by a 175°C maximum junction temperature. The device meets RoHS and halogen-free requirements per IEC 61249-2-21, and is qualified to AEC-Q101 for automotive underhood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous DC or RMS voltage the device blocks without clamping; sets operating margin for 12V/24V automotive systems. |
| VBR min/max | 66.7 / 81.5 V @ 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system nominal voltage. |
| VC @ IPPM | 107 V @ 4.9 A - Clamping voltage during 10/1000μs surge; defines worst-case overvoltage seen by protected ICs. |
| PPK | 500 W - Peak pulse power rating at TA = 25°C; derates linearly above 25°C per Fig.2. |
| TJ max | +175 °C - Maximum junction temperature; enables placement near hot components in engine control units. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with 0.400g mass; compatible with legacy through-hole assembly and reflow profiles. |
Pinout & Package
DO-204AC (DO-15) package with axial leads: cathode indicated by band marking; anode and cathode terminals are non-polarized in layout but functionally asymmetric for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-impedance return path; completes clamping loop during transient events. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., battery rail); avalanche conduction initiates here when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood use including temperature cycling, humidity, and mechanical shock per stress test plan. |
| 500W 10/1000μs surge rating | Withstands ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 3a/b (switching transients) without degradation. |
| Clamping voltage ≤107V at 4.9A | Ensures downstream 75V-rated ICs (e.g., CAN transceivers, microcontrollers) remain within safe operating area during surge. |
| Leakage <1 μA @ 60V | Minimizes standby power loss in always-on automotive modules such as body controllers and telematics units. |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Suppresses load dump transients (up to ±120V) on 12V/24V battery-fed ECUs in passenger vehicles and commercial trucks. IC Role / Device Role: Unidirectional TVS placed between battery rail and DC-DC converter input to clamp surges before regulation stage. Use Value: Prevents latch-up or permanent damage to buck controller ICs rated ≤75V, enabling compliance with ISO 16750-2. | Use Scenario: Protects digital input channels of programmable logic controllers from field-wiring induced transients in factory automation. IC Role / Device Role: Front-end surge limiter on 24V optocoupler input circuits exposed to relay coil switching noise. Use Value: Maintains signal integrity and extends optocoupler lifetime by limiting reverse voltage across LED anode-cathode to <107V. |
| LED Driver Overvoltage Clamp | ESD-Sensitive Sensor Interface |
Use Scenario: Guards constant-current LED driver ICs against flyback spikes generated by inductive LED string configurations. IC Role / Device Role: Parallel-connected TVS across driver output to clamp inductive kickback exceeding 60V VWM. Use Value: Eliminates need for snubber RC networks while maintaining >95% driver efficiency due to negligible leakage. | Use Scenario: Shields analog front-end of automotive ambient light or position sensors connected to exterior harnesses. IC Role / Device Role: First-stage protection on sensor supply line upstream of LDO regulator and ADC input. Use Value: Reduces system-level ESD failure rate by limiting transient energy entering sensitive CMOS analog circuitry. |
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 | Same 60V VWM, but SMA package (SMT); lower PPK (400W); clamping voltage 96.8V @ 4.3A. | Requires PCB redesign for surface-mount assembly; better suited for space-constrained control boards than underhood wiring harnesses. | Select SMAJ60A only if board space is limited and automotive qualification is not required. |
| P6KE60A | DO-15 package, same VWM, but non-AEC-Q101; PPK = 600W; clamping voltage 100V @ 5.2A. | Lacks automotive reliability validation; suitable for industrial/commercial equipment where AEC-Q101 is not mandated. | Choose P6KE60A for cost-sensitive non-automotive designs needing higher surge margin. |
Compared with SMAJ60A and P6KE60A, SA60AH uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and 500W 10/1000μs rating - making it the preferred choice for production automotive electronics requiring traceable, high-reliability surge protection without SMT conversion.

FAQ
What is the breakdown voltage range for SA60AH?
The SA60AH has a minimum breakdown voltage (VBR) of 66.7 V and a maximum of 81.5 V, measured at 1 mA test current per ANSI/IEEE C62.35. This range ensures consistent avalanche initiation above its 60 V working stand-off voltage while accommodating process variation across production lots.
Is SA60AH suitable for bidirectional transient protection?
No, SA60AH is a unidirectional TVS diode intended for DC rail protection with polarity-sensitive mounting (cathode band marks high-side connection). For bidirectional applications such as AC lines or data bus protection, SA60A or SA60CA variants must be used instead.
Does SA60AH meet automotive qualification standards?
Yes, SA60AH is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirming full stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life - required for underhood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of SA60AH during surge events?
The SA60AH clamps to a maximum of 107 V when subjected to its rated peak pulse current of 4.9 A under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry.
Can SA60AH replace SA60A in existing designs?
SA60AH can replace SA60A only if AEC-Q101 qualification is required and the application operates within automotive temperature and reliability constraints. Electrically, both share identical VWM, VBR, and clamping specs; however, SA60AH undergoes additional qualification testing and may differ in lot traceability and screening protocols.
