Product details
Overview
SA10AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of sensitive electronics. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V clamping voltage (VC) at 29.4 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive power supplies.
For engineers reviewing the SA10AHE3/54 datasheet, SA10AHE3/54 pinout, SA10AHE3/54 application, or SA10AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 1.0 µA reverse leakage at VWM, DO-15 mechanical compatibility, and verified clamping performance under repetitive surge conditions.
Technical Context
The SA10AHE3/54 operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its 11.1–12.3 V breakdown range at 1 mA test current. Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients.
It is rated for 500 W peak pulse power (10/1000 µs), 70 A non-repetitive forward surge current (10 ms half-sine), and dissipates up to 3.0 W continuously on an infinite heatsink at 75 °C lead temperature. The device meets JESD201 Class 2 whisker resistance and is RoHS-compliant with matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - defines precise avalanche onset threshold for reliable overvoltage detection |
| VC @ IPPM | 17.0 V at 29.4 A - limits protected circuit voltage during 500 W transient events |
| IPPM | 29.4 A - peak surge current capability with 10/1000 µs waveform, derated above 25 °C |
| ID @ VWM | 1.0 µA - ultra-low reverse leakage preserves signal integrity in high-impedance circuits |
| TJ max | 175 °C - supports operation in under-hood automotive and industrial environments |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges above 13.5 V. Use Value: Limits rail voltage to ≤17.0 V during 500 W pulses, preventing damage to MCU power domains and CAN transceivers. | Use Scenario: Shielding analog outputs of pressure/temperature sensors from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS connected across signal and ground to suppress sub-100 ns transients. Use Value: 1.0 µA leakage preserves microamp-level sensor bias currents; fast response avoids signal corruption. |
| Consumer Power Adapter Input Stage | Telecom DC Power Interface |
Use Scenario: Safeguarding AC-DC adapter primary-side rectifier and controller ICs from surge events. IC Role / Device Role / Timing Role: Mounted after bridge rectifier to clamp line-to-ground transients before bulk capacitor. Use Value: 175 °C TJ max enables reliable operation near hot components; DO-15 fits standard through-hole layouts. | Use Scenario: Protecting -48 V telecom power feeds from lightning-induced surges on outdoor equipment. IC Role / Device Role / Timing Role: Unidirectional TVS on negative rail, cathode tied to -48 V, anode to chassis ground. Use Value: 70 A IFSM handles 8.3 ms half-sine surges; AEC-Q101 qualification adds confidence in field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VWM (10 V), but SMA package (surface-mount); lower IPPM (24.7 A) and VC (16.0 V) | Requires PCB rework for SMT layout; better suited for space-constrained consumer designs | Select SMAJ10A only if board real estate is limited and peak surge energy is ≤400 W |
| P6KE10A | Same DO-15 package and VWM, but higher VC (17.5 V) and lower PPPM (600 W); not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use where qualification isn't mandated | Choose P6KE10A for cost-sensitive non-automotive systems needing marginally higher surge headroom |
Compared with SMAJ10A and P6KE10A, the SA10AHE3/54 delivers automotive-grade reliability in a through-hole package with optimized clamping (17.0 V) and verified 500 W capability - making it the preferred choice for production automotive modules requiring zero-layout change and full AEC-Q101 compliance.

FAQ
What is the clamping voltage of SA10AHE3/54 and how does it protect downstream components?
The SA10AHE3/54 has a maximum clamping voltage (VC) of 17.0 V at 29.4 A peak pulse current (10/1000 µs). This means that during a transient event, the SA10AHE3/54 limits the voltage seen by protected circuitry to no more than 17.0 V - well below typical IC absolute maximum ratings (e.g., 20–24 V), thereby preventing overvoltage damage to MCUs, sensors, or power controllers connected to the same rail.
Is SA10AHE3/54 suitable for automotive applications?
Yes, SA10AHE3/54 is AEC-Q101 qualified and manufactured with JESD201 Class 2 whisker-resistant matte tin plating. Its 175 °C maximum junction temperature, glass-passivated junction, and validated surge performance make it appropriate for under-hood and body-control module applications - confirmed in Vishay's official qualification report for the SAxxA-HE3 family.
What is the difference between SA10AHE3/54 and SA10AE3/54?
The SA10AHE3/54 is AEC-Q101 qualified (HE3 suffix), while SA10AE3/54 is commercial-grade (E3 suffix) with identical electrical specs but no automotive qualification testing. Both share DO-15 packaging, 10 V VWM, and 500 W PPPM - but only SA10AHE3/54 carries the formal AEC-Q101 certification required for automotive production.
Can SA10AHE3/54 be used in bidirectional protection circuits?
No - SA10AHE3/54 is unidirectional (denoted by "A" suffix). For bidirectional protection, Vishay specifies the "CA" variant (e.g., SA10CA). Using SA10AHE3/54 in bidirectional configurations risks forward conduction during negative transients, leading to improper clamping and potential device failure.
What is the lead finish and soldering compatibility of SA10AHE3/54?
SA10AHE3/54 features matte tin-plated leads compliant with J-STD-002 and JESD22-B102 for reliable solderability. It supports wave and hand soldering at ≤275 °C for 10 seconds (per JESD22-B106), and passes JESD201 Class 2 whisker testing - ensuring robust interconnect integrity in high-reliability manufacturing.
