Product details
Overview
1.5SMC200CA-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, 200 V standoff voltage (VWM), and clamping voltage of 328 V at 4.6 A peak pulse current - deployed 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 1.5SMC200CA-M3/57T datasheet, 1.5SMC200CA-M3/57T pinout, 1.5SMC200CA-M3/57T application, or 1.5SMC200CA-M3/57T equivalent, this device delivers verified bidirectional clamping performance, halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification readiness - critical for high-reliability board-level ESD and surge protection design.
Technical Context
The 1.5SMC200CA-M3/57T operates as a symmetric bidirectional TVS diode, leveraging glass-passivated silicon junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its breakdown voltage is specified at 237–263 V (min/max) under 1 mA test current, ensuring robust overvoltage threshold stability across temperature.
Designed for surface-mount assembly on standard PCB copper pads (8.0 mm × 8.0 mm per terminal), it sustains repetitive 10/1000 μs pulses at 0.01% duty cycle and derates linearly above 25 °C ambient, with thermal resistance junction-to-ambient of 75 °C/W and junction-to-leads of 15 °C/W - enabling predictable thermal management in compact power-supply and interface protection layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - maximum continuous reverse operating voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 237–263 V at 1 mA - precise voltage threshold where avalanche conduction begins; ensures consistent surge triggering across units. |
| VC (Clamping) | 328 V at IPPM = 4.6 A - peak voltage seen by protected circuit during 10/1000 μs transient; determines downstream component stress level. |
| PPPM | 1500 W - peak pulse power handling capability under standardized 10/1000 μs waveform; validates robustness against IEC 61000-4-5 surge events. |
| ID (Leakage) | <1 μA at 200 V - ultra-low reverse leakage ensures minimal standby power loss and signal integrity in high-impedance sensing paths. |
| TJ max. | +150 °C - maximum junction temperature rating; supports operation in under-hood automotive and industrial environments. |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with automated pick-and-place. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, polarity-unmarked for bidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche terminals | No polarity marking; either terminal serves as anode or cathode depending on transient polarity - enables single-device protection of AC or differential lines. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Validated surge immunity for IEC 61000-4-5 Level 4 (4 kV line-to-line) when properly mounted on 8 mm × 8 mm copper pads. |
| Glass-passivated chip junction | Ensures stable breakdown characteristics, low leakage drift over time, and resistance to humidity-induced parameter shift. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IPC-1752A material declaration requirements and EU Directive 2015/863 for restricted substances in electronics manufacturing. |
| MSL Level 1 (JEDEC J-STD-020) | Zero floor life limitation - can be stored indefinitely at ≤30 °C/60% RH without baking prior to reflow soldering. |
| AEC-Q101 qualification path | Base P/NHM3_X variant available for automotive-grade production; this M3/57T version shares identical die and construction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Lower PPPM (600 W), same VWM (200 V), SMB package (smaller footprint, higher RθJA = 110 °C/W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 without parallel devices | Select when board space is constrained and surge threat level is ≤1 kV line-to-ground. |
| 1.5KE200CA | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly and higher thermal resistance | Requires manual or wave-solder process; not viable for automated high-volume production | Choose only for legacy through-hole designs or prototyping where rework tolerance outweighs production efficiency. |
Compared with SMBJ200CA and 1.5KE200CA, the 1.5SMC200CA-M3/57T uniquely balances 1500 W surge capacity, SMT manufacturability, and thermal performance in the DO-214AB outline - making it the optimal choice for new automotive and industrial designs requiring AEC-Q101 scalability and high-power transient resilience.

FAQ
What is the clamping voltage of the 1.5SMC200CA-M3/57T under a 10/1000 μs surge?
The 1.5SMC200CA-M3/57T has a maximum clamping voltage (VC) of 328 V at a peak pulse current (IPPM) of 4.6 A under the standardized 10/1000 μs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal, as defined in the Vishay datasheet revision 09-Mar-2026. The 1.5SMC200CA-M3/57T maintains this clamping performance across its qualified operating temperature range.
Is the 1.5SMC200CA-M3/57T suitable for automotive applications?
Yes - the 1.5SMC200CA-M3/57T uses the same die and construction as the AEC-Q101-qualified HM3 variants (e.g., 1.5SMC200CAHM3_B/H). While the M3/57T itself carries commercial-grade qualification, its halogen-free, RoHS-compliant materials, MSL Level 1 rating, and thermal performance align with automotive supply chain requirements. For production automotive use, specify the HM3_X suffix version; the 1.5SMC200CA-M3/57T is ideal for pre-qualification testing and industrial-grade deployment.
Does the 1.5SMC200CA-M3/57T have polarity markings?
No - the 1.5SMC200CA-M3/57T is a bidirectional TVS diode and carries no polarity marking on the SMC (DO-214AB) package. Its symmetrical structure means either end functions identically under positive or negative transients, eliminating orientation concerns during placement. This contrasts with unidirectional variants like 1.5SMC200A, which feature a cathode band.
What is the maximum operating temperature for the 1.5SMC200CA-M3/57T?
The 1.5SMC200CA-M3/57T has a maximum junction temperature (TJ max.) of +150 °C and an operating junction/storage temperature range of –65 °C to +150 °C. Its thermal resistance junction-to-ambient is 75 °C/W under standard mounting conditions, meaning power dissipation must be limited to maintain safe junction temperatures - especially in enclosed or high-ambient environments. Derating curves in the datasheet guide thermal design for the 1.5SMC200CA-M3/57T.
How does the 1.5SMC200CA-M3/57T compare to the 1.5SMC200A variant?
The 1.5SMC200CA-M3/57T is bidirectional with symmetrical clamping, while the 1.5SMC200A is unidirectional and features a cathode band. Both share identical VWM (200 V), VBR (237–263 V), and PPPM (1500 W), but the 1.5SMC200CA-M3/57T supports AC-coupled or differential-line protection without polarity constraints. The "CA" suffix explicitly denotes bidirectionality, and the "M3" confirms halogen-free RoHS compliance - a distinction critical for layout and compliance documentation of the 1.5SMC200CA-M3/57T.
