Product details
Overview
SA100CA-E3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor diode in DO-15 package, rated for 100 V standoff voltage (VWM), 123 V minimum breakdown voltage (VBR), 162 V maximum clamping voltage (VC) at 3.1 A peak pulse current, and 500 W peak pulse power with 10/1000 μs waveform. It protects signal lines and power rails in automotive sensor units and industrial I/O interfaces.
For engineers reviewing the SA100CA-E3/54 datasheet, SA100CA-E3/54 pinout, SA100CA-E3/54 application, or SA100CA-E3/54 equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, DO-15 mechanical compatibility, and 175 °C junction temperature rating for under-hood or high-reliability embedded use.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. It exhibits low incremental clamping resistance and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced transients, and inductive switching spikes on unshielded lines.
Designed for repetitive surge events at ≤0.01% duty cycle, it delivers 500 W peak pulse power while maintaining stable clamping performance across -55 °C to +175 °C operating range. Its glass-passivated junction ensures robust reliability under thermal cycling and high-humidity conditions typical in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected circuit's normal operating rail. |
| VBR (min) | 123 V - Minimum breakdown voltage at 1 mA test current; guarantees clamping activation above system nominal voltage. |
| VC (max) | 162 V - Maximum clamped voltage at 3.1 A IPPM; defines worst-case overvoltage seen by downstream ICs during surge. |
| PPPM | 500 W - Peak pulse power handling with 10/1000 μs waveform; determines survivability against standard lightning/surge test pulses. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in engine control units, motor drives, and other high-ambient-temperature locations. |
| ID @ VWM | 1.0 μA - Reverse leakage at 100 V; ensures negligible standby power loss and no signal integrity impact on high-impedance nodes. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronics, including temperature cycling, HTRB, and ESD. |
Pinout & Package
Package: DO-15 (DO-204AC) - axial-leaded, molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability standards. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | DO-214AA package; 1.5× larger footprint; 600 W PPPM; 165 V VC at 3.2 A | Higher power handling but requires PCB re-layout; better suited for higher-energy surge environments | Select SMBJ100CA only if existing design allows DO-214AA footprint and needs >500 W margin. |
| 1.5KE100CA | DO-201AD package; 1500 W PPPM; 165 V VC at 9.2 A; larger thermal mass | Designed for primary-level AC line protection; not optimized for signal-line speed or space-constrained layouts | Choose 1.5KE100CA for bulk AC input protection where fast response is secondary to energy absorption. |
Compared with SA100CA-E3/54, SMBJ100CA offers higher surge rating in a surface-mount format ideal for automated assembly, while 1.5KE100CA provides greater energy capacity at the cost of slower response and larger size-making SA100CA-E3/54 optimal for compact, high-speed, bidirectional signal line protection in automotive and industrial edge nodes.

FAQ
What is the clamping voltage of SA100CA-E3/54 at its rated peak pulse current?
The SA100CA-E3/54 has a maximum clamping voltage (VC) of 162 V at 3.1 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured across both terminals during transient conduction and defines the upper voltage limit imposed on protected circuitry during surge events. The SA100CA-E3/54 maintains this clamping performance consistently across its full operating temperature range.
Is SA100CA-E3/54 suitable for automotive applications?
Yes, SA100CA-E3/54 is AEC-Q101 qualified and explicitly designed for automotive use cases including sensor interfaces, body control modules, and infotainment power rails. Its DO-15 package, 175 °C maximum junction temperature, and bidirectional clamping symmetry meet stringent requirements for under-hood and chassis-mounted electronics. The SA100CA-E3/54 also complies with JESD201 whisker testing (Class 1A) and UL 94 V-0 flammability standards.
How does the bidirectional nature of SA100CA-E3/54 affect its circuit placement?
The SA100CA-E3/54 has no polarity marking and conducts identically in both directions, making it ideal for AC-coupled lines, differential buses (e.g., RS-485), or floating sensor outputs where voltage polarity reversal may occur. Unlike unidirectional TVS diodes, the SA100CA-E3/54 eliminates orientation errors during assembly and ensures symmetric protection without requiring additional series components. Its DO-15 axial package supports through-hole mounting directly at board edges or connectors.
What is the maximum steady-state power dissipation for SA100CA-E3/54?
The SA100CA-E3/54 has a maximum steady-state power dissipation (PD) of 3.0 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C. This rating applies to continuous DC or low-frequency reverse-bias conditions-not transient events. In normal operation, leakage current remains below 1.0 μA at 100 V, resulting in negligible static power loss. The SA100CA-E3/54 is not intended for sustained forward conduction.
Does SA100CA-E3/54 require external series impedance for proper operation?
No, SA100CA-E3/54 functions as a standalone clamping device and does not require external series impedance for basic surge suppression. However, in high-energy applications (e.g., IEC 61000-4-5 Level 4), a current-limiting resistor or PTC may be added upstream to reduce peak current stress on the SA100CA-E3/54 and extend its operational lifetime. The SA100CA-E3/54's low incremental surge resistance ensures effective clamping even without added impedance.
