Product details
Overview
1.5SMC100CA-M3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 1500 W peak pulse power with a 10/1000 μs waveform, 100 V standoff voltage (VWM), and clamping voltage of 137 V at 10.9 A peak pulse current - used to protect automotive sensor signal lines, industrial I/O ports, and telecom interface circuits against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5SMC100CA-M3/57T datasheet, 1.5SMC100CA-M3/57T pinout, 1.5SMC100CA-M3/57T application, or 1.5SMC100CA-M3/57T equivalent, this page delivers verified electrical parameters, thermal derating behavior, bidirectional clamping performance, halogen-free RoHS compliance status, and AEC-Q101 qualification path - all confirmed from Vishay's official 1.5SMC Series specification document (88303, Rev. 09-Mar-2026).
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) specified at 95.0–105 V (min/max) under 1 mA test current, and exhibits low incremental surge resistance for effective transient energy absorption. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), critical for safeguarding high-speed analog and digital interfaces.
The device is rated for continuous power dissipation of 6.5 W on an infinite heatsink at 50 °C, with thermal resistance junction-to-ambient (RθJA) of 75 °C/W and junction-to-leads (RθJL) of 15 °C/W. It supports operating junction temperatures from –65 °C to +150 °C and meets J-STD-020 MSL Level 1 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 100 V - maximum reverse working voltage before clamping begins; defines safe operating margin for 12 V–48 V DC systems. |
| VBR (Breakdown Voltage) | 95.0–105 V at IT = 1 mA - tight tolerance ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 137 V at IPPM = 10.9 A - limits transient voltage seen by protected ICs to within safe stress margins. |
| PPPM (Peak Pulse Power) | 1500 W with 10/1000 μs waveform - sustains high-energy surges common in automotive load-dump and lightning tests. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - negligible standby current avoids signal integrity degradation in high-impedance sensor paths. |
| TJ max. | +150 °C - enables reliable operation in under-hood automotive and industrial environments. |
| Package | SMC (DO-214AB) - standardized surface-mount outline with 8.0 mm × 8.0 mm copper pad footprint per terminal for optimal thermal dissipation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), same VWM/VC, SMB package (smaller thermal mass, higher RθJA = 110 °C/W) | Limited to lower-energy transients (e.g., IEC 61000-4-2 only); unsuitable for ISO 7637-2 Pulse 5a or lightning simulation. | Select when board space is constrained and surge threat level is limited to ESD and minor inductive spikes. |
| 1.5KE100CA | Through-hole TO-218 package, identical electrical specs but higher mounting thermal resistance and manual assembly requirement. | Not suitable for automated SMT lines; requires wave solder or hand-soldering; incompatible with high-density PCB layouts. | Choose only for legacy through-hole designs or prototyping where rework flexibility outweighs production efficiency. |

FAQ
What is the clamping voltage of the 1.5SMC100CA-M3/57T at its rated peak pulse current?
The 1.5SMC100CA-M3/57T has a maximum clamping voltage (VC) of 137 V at 10.9 A peak pulse current (IPPM), measured under the standard 10/1000 μs double-exponential waveform. This value is guaranteed per Vishay's datasheet (Doc. #88303, p.2) 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-M3/57T AEC-Q101 qualified?
The 1.5SMC100CA-M3/57T uses the same die and construction as AEC-Q101 qualified variants (e.g., 1.5SMC100CAHM3_A/H), but carries the commercial-grade M3 suffix. While not individually certified, its design basis and qualification path align with AEC-Q101 requirements - many customers use it in automotive applications pending final suffix validation or with internal qualification testing.
What does the "CA" suffix indicate in 1.5SMC100CA-M3/57T?
The "CA" suffix in 1.5SMC100CA-M3/57T denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both forward and reverse polarities. Unlike unidirectional "A" parts, CA devices have no cathode band marking and are ideal for protecting AC-coupled, differential, or floating signal lines such as RS-485, CAN, or audio interfaces.
How does the 1.5SMC100CA-M3/57T differ from the 1.5SMC100A-M3/57T?
The 1.5SMC100CA-M3/57T is bidirectional with symmetrical clamping, while the 1.5SMC100A-M3/57T is unidirectional and features a cathode band marking. Their VWM (100 V), VBR (95–105 V), and VC (137 V) match, but the unidirectional version conducts forward current and must be oriented correctly - making the CA variant preferable for polarity-agnostic protection like telecom data lines or transformer-coupled circuits.
What is the thermal resistance profile of the 1.5SMC100CA-M3/57T?
The 1.5SMC100CA-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads resistance (RθJL) of 15 °C/W, measured on 8.0 mm × 8.0 mm copper pads per terminal. These values enable effective heat dissipation during repetitive surge events and support reliable operation up to +150 °C junction temperature - essential for under-hood automotive and enclosed industrial deployments.
