Product details
Overview
1.5SMC100CA-E3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 100 V standoff voltage (VWM), 114 V minimum breakdown voltage (VBR), 137 V maximum clamping voltage (VC) at 10.9 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the 1.5SMC100CA-E3/57T datasheet, 1.5SMC100CA-E3/57T pinout, 1.5SMC100CA-E3/57T application, or 1.5SMC100CA-E3/57T equivalent, this page delivers verified electrical parameters, SMC (DO-214AB) package details, bidirectional clamping behavior, thermal resistance (RθJA = 75 °C/W), and AEC-Q101-qualified alternatives for automotive-grade design-in.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance regardless of transient polarity - critical for protecting AC-coupled or floating signal paths. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables rapid energy diversion during ESD or lightning-induced surges.
The device is rated for repetitive 10/1000 μs transients at 0.01% duty cycle and supports operation from −65 °C to +150 °C junction temperature. Mounting on 8.0 mm × 8.0 mm copper pads achieves specified thermal performance, and its MSL Level 1 rating confirms suitability for standard reflow processes up to 260 °C peak.

Use Scenario: Suppressing inductive kickback from brushed DC motors and solenoids in washing machines, HVAC actuators, and power tools. IC Role / Device Role / Timing Role: Across motor terminals or H-bridge outputs to clamp flyback voltage spikes generated during PWM switching. Use Value: Limits reverse voltage to ≤137 V during 200 A IFSM events - preventing MOSFET avalanche failure and extending driver IC lifetime. |
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 | Lower peak power (600 W), same VWM/VC, SMB package (smaller footprint, higher RθJA) | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy surges in space-constrained designs | Select when board area is critical and surge threat level is ≤1 kV (IEC 61000-4-5 Level 2) |
| 1.5KE100CA | Higher RθJA (100 °C/W), axial leaded DO-201 package, same electrical specs but manual assembly only | Not suitable for automated SMT lines; requires through-hole routing and wave soldering | Select only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with 1.5SMC100CA-E3/57T, SMBJ100CA trades peak power for compactness, while 1.5KE100CA retains identical clamping but sacrifices SMT manufacturability - making the 1.5SMC100CA-E3/57T optimal for high-reliability, high-volume automotive and industrial SMT production.

FAQ
What is the clamping voltage of the 1.5SMC100CA-E3/57T at its rated peak pulse current?
The 1.5SMC100CA-E3/57T has a maximum clamping voltage (VC) of 137 V at 10.9 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet (Document Number 88303, Rev. 09-Mar-2026) and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC100CA-E3/57T suitable for automotive applications?
Yes - the base 1.5SMC100CA-E3/57T is RoHS-compliant and commercial-grade, but Vishay offers AEC-Q101-qualified variants (e.g., 1.5SMC100CAHE3_A) with identical electrical specs. The 1.5SMC100CA-E3/57T itself shares the same die, package, and process as qualified versions, and its −65 °C to +150 °C operating range and MSL Level 1 rating align with automotive under-hood requirements when used per design guidelines.
How does the bidirectional configuration of the 1.5SMC100CA-E3/57T affect PCB layout?
The 1.5SMC100CA-E3/57T has no polarity marking and functions identically in both directions - simplifying layout by eliminating orientation constraints. Engineers can place it across differential lines, AC-coupled signals, or floating supplies without verifying anode/cathode alignment. This symmetry reduces assembly errors and supports compact, symmetric routing in high-speed or noise-sensitive interfaces.
What is the thermal resistance of the 1.5SMC100CA-E3/57T, and how does it impact PCB design?
The 1.5SMC100CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures during repetitive surges, designers must allocate sufficient copper area and consider airflow - undersized pads will cause excessive temperature rise, degrading clamping consistency and long-term reliability.
Does the 1.5SMC100CA-E3/57T meet industry surge immunity standards?
Yes - the 1.5SMC100CA-E3/57T's 1500 W peak pulse power rating with a 10/1000 μs waveform directly supports compliance with IEC 61000-4-5 Level 4 (4 kV line-earth, 2 kV line-line) when implemented with proper PCB layout (e.g., short traces, adequate ground plane). Its low clamping voltage and fast response also contribute to meeting IEC 61000-4-2 ESD immunity requirements in system-level testing.
