Product details
Overview
SA160CHE3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for robust overvoltage protection of sensitive electronics. It features a 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 μs), clamping voltage of 259 V at 1.9 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA160CHE3/54 datasheet, SA160CHE3/54 pinout, SA160CHE3/54 application, or SA160CHE3/54 equivalent, this device is selected for high-energy transient suppression in automotive power lines, industrial sensor interfaces, and telecom signal conditioning where bidirectional surge immunity and RoHS-compliant, whisker-tested leads are required.
Technical Context
The SA160CHE3/54 operates as a bi-directional avalanche diode with symmetrical clamping behavior in both polarities, enabling protection against positive and negative transients without polarity dependency. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, critical for consistent clamping under repetitive surges.
Designed for 10/1000 μs waveform compliance, it delivers 500 W peak pulse power with derating above 25 °C per Fig. 2 and supports steady-state dissipation up to 3.0 W on an infinite heatsink at TL = 75 °C. Junction temperature range spans −55 °C to +175 °C, supporting under-hood and industrial ambient conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ160CA | Same DO-214AC (SMA) package; 160 V VWM, 259 V VC @ 1.9 A, but rated for 400 W PPPM (vs. 500 W). | Lower peak power limits suitability for ISO 7637-2 Pulse 5a (load dump) in high-current automotive modules. | Select when space-constrained SMT layout is mandatory and 400 W surge capacity suffices. |
| ON Semiconductor 1.5KE160CA | DO-201AD package; identical 160 V VWM and 259 V VC, but higher 1.5 kW PPPM rating and 100 A IFSM (uni-directional only variant). | Not AEC-Q101 qualified; lacks automotive traceability and whisker-test certification required for Tier 1 suppliers. | Prefer for industrial AC/DC front-ends where higher surge margin is needed and automotive qualification is not mandated. |
Compared with SMAJ160CA and 1.5KE160CA, SA160CHE3/54 uniquely combines AEC-Q101 qualification, DO-204AC through-hole compatibility, 500 W pulse rating, and JESD 201 Class 2 whisker resistance-making it the preferred choice for automotive and high-reliability industrial through-hole designs requiring full compliance documentation.

FAQ
What is the clamping voltage of SA160CHE3/54 and how is it measured?
The SA160CHE3/54 has a maximum clamping voltage (VC) of 259 V at 1.9 A peak pulse current (IPPM), tested with a 10/1000 μs waveform per IEC 61000-4-5. This value represents the upper voltage limit imposed on protected circuitry during a standardized surge event and is confirmed in the Vishay datasheet Document Number 88378, page 2.
Is SA160CHE3/54 suitable for automotive applications?
Yes, SA160CHE3/54 is AEC-Q101 qualified and carries the HE3 suffix indicating compliance with JESD 201 Class 2 whisker testing and RoHS requirements. It is explicitly intended for automotive power line and signal protection, including engine control, body electronics, and ADAS sensor modules per Vishay's application guidance.
What does the "HE3" suffix mean in SA160CHE3/54?
The "HE3" suffix denotes that SA160CHE3/54 is RoHS-compliant and AEC-Q101 qualified, with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance requirements. It distinguishes this automotive-grade variant from commercial-grade "E3" versions lacking AEC-Q101 validation.
Can SA160CHE3/54 replace a uni-directional TVS like SA160A?
No-SA160CHE3/54 is bi-directional and lacks polarity marking, while SA160A is uni-directional with a cathode band. Substitution requires verifying circuit symmetry: SA160CHE3/54 may be used only where bidirectional protection is needed or where the original design already accommodates non-polarized placement.
What is the thermal derating behavior of SA160CHE3/54 above 25 °C?
SA160CHE3/54 follows the pulse derating curve in Figure 2 of datasheet 88378: peak pulse power decreases linearly from 100 % at 25 °C to ~50 % at 125 °C ambient. For continuous operation, steady-state power dissipation drops from 3.0 W at TL = 75 °C per Figure 5, requiring appropriate lead length and PCB copper area for thermal management.
