Product details
Overview
SA10CHE3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features a 10 V stand-off voltage (VWM), 12.3 V maximum breakdown voltage (VBR), 17.0 V clamping voltage at 29.4 A peak pulse current (IPPM), 500 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the SA10CHE3/54 datasheet, SA10CHE3/54 pinout, SA10CHE3/54 application, or SA10CHE3/54 equivalent, this device is selected for robust ESD and surge protection in automotive sensor interfaces, industrial I/O lines, and telecom power rails where bidirectional clamping, low leakage (<1.0 μA), and high reliability under thermal stress are required.
Technical Context
The SA10CHE3/54 operates as a bi-directional avalanche diode, symmetrically clamping transient voltages above ±12.3 V in either polarity while maintaining ≤10 V reverse stand-off. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced surges.
Designed for repetitive 10/1000 μs waveform exposure at 0.01% duty cycle, it delivers 500 W peak pulse power with derating above 25 °C ambient and supports continuous power dissipation of 3.0 W on an infinite heatsink. Junction temperature range spans –55 °C to +175 °C, validated per AEC-Q101 stress tests.
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 |
|---|---|---|---|
| SMAJ10CA | Same DO-214AC package; 10 V VWM, 11.1–12.3 V VBR, 17.0 V VC @ 29.4 A - identical clamping but lower 400 W PPPM rating | Limited to lower-energy surges (IEC 61000-4-5 Level 3); not AEC-Q101 qualified | Select SMAJ10CA only for cost-sensitive consumer applications where automotive qualification and 500 W headroom are unnecessary |
| P6SMB10CA | DO-214AA package; same 10 V VWM and 17.0 V VC, but 600 W PPPM and higher 32.4 A IPPM - larger footprint and higher surge margin | Better suited for industrial mains-input protection; requires PCB layout change due to wider body and lead spacing | Choose P6SMB10CA when system-level surge testing exceeds IEC 61000-4-5 Level 4 or when extended thermal margin is critical |
Compared with SMAJ10CA and P6SMB10CA, SA10CHE3/54 uniquely balances AEC-Q101 qualification, DO-15 through-hole compatibility, and full 500 W surge capability - making it optimal for space-constrained automotive modules where reliability and legacy board assembly are priorities.

FAQ
What is the polarity configuration of SA10CHE3/54?
SA10CHE3/54 is a bi-directional TVS diode with no polarity marking on the DO-204AC package. Its symmetrical avalanche structure provides identical clamping behavior for positive and negative transients, eliminating orientation constraints during PCB assembly and enabling use on AC-coupled or differential lines.
Does SA10CHE3/54 meet automotive qualification standards?
Yes, SA10CHE3/54 carries the HE3 suffix, confirming AEC-Q101 qualification. This includes validation across high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress testing (HAST), ensuring suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of SA10CHE3/54 under surge conditions?
The maximum clamping voltage (VC) of SA10CHE3/54 is 17.0 V at 29.4 A peak pulse current (IPPM) using 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 circuits during transient events.
How does SA10CHE3/54 differ from uni-directional SA10A?
SA10CHE3/54 is bi-directional with no cathode marking and symmetric clamping in both polarities, whereas SA10A is uni-directional with a cathode band and only clamps reverse transients. SA10CHE3/54 has identical VWM (10 V) and VC (17.0 V) but is rated for bidirectional surge paths - essential for AC signal lines or floating supplies.
Is SA10CHE3/54 compatible with lead-free reflow and wave soldering processes?
Yes, SA10CHE3/54 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. It withstands solder dip up to 275 °C for 10 seconds and is rated for lead-free reflow profiles, including peak temperatures up to 260 °C per JEDEC J-STD-020.
