Product details
Overview
SA100CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 100 V stand-off voltage (VWM), 123 V minimum breakdown voltage (VBR), 162 V maximum clamping voltage (VC) at 3.1 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the SA100CAHE3/54 datasheet, SA100CAHE3/54 pinout, SA100CAHE3/54 application, or SA100CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, low incremental surge resistance, and compliance with IEC 61000-4-2/4-4/4-5 transient immunity standards.
Technical Context
This TVS diode operates symmetrically in both directions, with identical VBR (111–123 V), VC (≤162 V), and ID (≤1.0 μA at VWM) specifications for reverse and forward quadrants. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns) to ESD and lightning-induced surges.
The device is rated for TJ = –55 °C to +175 °C operation, supports 8.3 ms half-sine surge events up to 70 A (unidirectional only), and exhibits a temperature coefficient of +123 mV/°C - enabling predictable clamping voltage drift across automotive under-hood temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 111 V / 123 V at 1 mA - defines reliable conduction onset window for bidirectional transient suppression |
| VC @ IPPM | 162 V at 3.1 A (10/1000 μs) - peak clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 500 W - surge energy handling capacity per single 10/1000 μs pulse, derated above 25 °C |
| ID @ VWM | ≤1.0 μA - leakage current level ensuring minimal standby power loss and signal integrity in high-impedance lines |
| TJ max. | +175 °C - enables deployment in engine control units and powertrain modules without thermal derating penalties |
| AEC-Q101 | Qualified - certified for automotive electronic systems requiring robustness against temperature cycling, humidity, and mechanical shock |
Pinout & Package
SA100CAHE3/54 uses the DO-15 (DO-204AC) axial-leaded package: molded epoxy body, matte tin-plated leads solderable per J-STD-002, UL 94 V-0 rated, with no polarity marking (bidirectional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient current entry point in negative half-cycle | Conducts surge current during negative voltage excursions; symmetric with cathode under bidirectional operation |
| Cathode (Lead 2) | Transient current entry point in positive half-cycle | Conducts surge current during positive voltage excursions; functionally identical to anode due to bidirectional symmetry |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, repeatable breakdown voltage with <±5 % tolerance and minimal parameter drift over lifetime |
| 500 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 3 (1 kV line-to-line, 2 kV line-to-earth) surge immunity without external series impedance |
| AEC-Q101 qualification | Validates reliability for automotive applications including ADAS camera modules and body control units |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage stress on downstream ICs such as CAN transceivers or microcontroller I/O pins |
| DO-15 mechanical compatibility | Direct drop-in replacement for legacy TVS diodes in existing through-hole PCB layouts with 0.375" lead spacing |

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 SMAJ100CA | Same DO-214AC package; slightly higher VC (165 V) and lower IPPM (3.0 A); RoHS-compliant but not AEC-Q101 qualified | Preferred for commercial telecom or industrial equipment where automotive qualification is unnecessary | Select when footprint compatibility with SMC/SMA packages is required and AEC-Q101 is not mandated |
| ON Semiconductor 1.5SMC100CA | DO-214AB package; identical VWM/VC specs; 1.5 kW rating (10/1000 μs); higher thermal mass but larger footprint | Suitable for high-reliability power supply input stages needing greater single-pulse margin | Choose when system-level surge testing exceeds 500 W and board space allows larger SMC package |
Compared with SMAJ100CA and 1.5SMC100CA, SA100CAHE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and precise 100 V stand-off in a cost-optimized automotive-grade TVS - making it optimal for space-constrained, thermally demanding, and safety-critical vehicle subsystems.

FAQ
What is the clamping voltage of SA100CAHE3/54 under a 10/1000 μs surge?
The SA100CAHE3/54 has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak pulse current of 3.1 A with a 10/1000 μs waveform. This value is measured across the device terminals during transient conduction and represents the upper voltage limit imposed on protected circuitry - critical for ensuring downstream ICs remain within absolute maximum ratings. The SA100CAHE3/54 maintains this performance across its full operating temperature range.
Is SA100CAHE3/54 suitable for automotive applications?
Yes, SA100CAHE3/54 is AEC-Q101 qualified and specifically designed for automotive use cases including sensor interfaces, body electronics, and infotainment systems. Its DO-15 package, –55 °C to +175 °C operating range, and robust surge handling meet stringent automotive environmental and reliability requirements. The HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - confirming suitability for under-hood and chassis-mounted modules.
How does SA100CAHE3/54 differ from unidirectional SA100A variants?
SA100CAHE3/54 is bidirectional with symmetrical electrical characteristics in both polarities - no cathode marking, identical VBR and VC in positive and negative directions. In contrast, SA100A is unidirectional, features a cathode band, conducts only in reverse bias, and has different forward voltage (VF = 3.5 V at 100 A). SA100CAHE3/54 is selected for AC-coupled or floating signal lines; SA100A suits DC-biased power rails where polarity is fixed.
What is the leakage current specification for SA100CAHE3/54 at rated stand-off voltage?
At its 100 V stand-off voltage (VWM) and TA = 25 °C, SA100CAHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA. This ultra-low leakage preserves signal integrity on high-impedance sensor lines and minimizes standby power loss in battery-operated automotive modules. Leakage remains ≤5.0 μA up to TJ = 125 °C, supporting reliable operation in elevated ambient conditions.
Can SA100CAHE3/54 be used in place of older SA100CA-E3/54 parts?
Yes, SA100CAHE3/54 is a direct functional and mechanical replacement for SA100CA-E3/54, sharing identical electrical specs, DO-15 package dimensions, and lead finish. The HE3 suffix adds AEC-Q101 qualification and enhanced whisker resistance (JESD 201 Class 2), while E3 indicates commercial-grade RoHS compliance only. No PCB layout or schematic changes are needed when upgrading to SA100CAHE3/54 in existing designs requiring automotive qualification.
