Product details
Overview
SA160AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for circuit protection against ESD, lightning surges, and inductive switching transients. It features 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR) at 1 mA, 259 V clamping voltage (VC) at 1.9 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 μs waveform.
For engineers reviewing the SA160AHE3/54 datasheet, SA160AHE3/54 pinout, SA160AHE3/54 application, or SA160AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 mechanical compatibility, 175 °C max junction temperature, low incremental surge resistance, and verified clamping performance under repetitive 0.01% duty cycle pulses.
Technical Context
The SA160AHE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling fast response time (<1 ns) and stable breakdown behavior across temperature. Its unidirectional polarity uses a cathode band marking and supports DC-biased protection paths in power rails and signal lines.
It delivers 500 W peak pulse power per 10/1000 μs waveform, derated linearly above 25 °C ambient, with steady-state power dissipation of 3.0 W on infinite heatsink at 75 °C lead temperature. The device sustains 70 A non-repetitive forward surge current (IFSM) and exhibits 1.0 μA maximum reverse leakage at 160 V.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/52 | Same VWM (160 V), identical DO-214AC package, but lower PPPM (400 W) and higher VC (274 V at 1.7 A) | Less robust clamping margin; unsuitable for high-energy IEC 61000-4-5 Level 4 testing | Select SMAJ160A-E3/52 only when board space constraints require SMD mounting and surge energy is limited to ≤400 W |
| 1.5KE160A | Higher PPPM (1500 W), larger DO-201AD package, same VWM and VBR range, but no AEC-Q101 qualification | Not validated for automotive use; requires additional qualification effort for automotive OEM programs | Choose 1.5KE160A where extreme surge energy handling is required and automotive qualification is not mandated |
Compared with SMAJ160A-E3/52 and 1.5KE160A, the SA160AHE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and 500 W PPPM-making it optimal for cost-sensitive, high-reliability automotive and industrial control designs requiring proven qualification and legacy PCB compatibility.

FAQ
What is the clamping voltage of the SA160AHE3/54 under standard surge conditions?
The SA160AHE3/54 has a maximum clamping voltage (VC) of 259 V when subjected to a 10/1000 μs waveform at 1.9 A peak pulse current (IPPM). This value is measured per JEDEC standards and reflects the actual voltage seen by downstream components during transient events, ensuring protection of 300 V-rated capacitors and 200 V MOSFETs in 160 V systems.
Is the SA160AHE3/54 qualified for automotive applications?
Yes, the SA160AHE3/54 carries the HE3 suffix, indicating full AEC-Q101 qualification per Rev. 27-Sep-2021 documentation. It is tested for temperature cycling, humidity bias, mechanical shock, and surge endurance-making it suitable for engine control units, body electronics, and ADAS power domains where zero-defect reliability is required.
What does the "HE3" suffix mean in SA160AHE3/54?
The "HE3" suffix in SA160AHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade E3 versions and confirms enhanced process controls, extended temperature validation, and automotive-grade traceability for the SA160AHE3/54.
Can SA160AHE3/54 be used in bidirectional protection circuits?
No, SA160AHE3/54 is strictly unidirectional, as indicated by the "A" (not "CA") suffix and presence of cathode band marking. For bidirectional operation, Vishay specifies SA160CA variants. Using SA160AHE3/54 in AC-coupled or symmetrical surge environments risks forward conduction failure and inadequate negative-going transient suppression.
What is the maximum operating temperature for SA160AHE3/54?
The SA160AHE3/54 has a maximum junction temperature (TJ) rating of +175 °C, verified per the 88378 datasheet. This allows reliable operation in under-hood automotive locations and sealed industrial enclosures where ambient temperatures exceed 125 °C, provided thermal design maintains junction-to-ambient resistance below calculated limits.
