Product details
Overview
1.5SMC200CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, designed for high-energy surge protection. It features a 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), 1500 W peak pulse power (10/1000 μs), clamping voltage of 328 V at 4.6 A IPPM, and AEC-Q101 qualification for automotive applications.
For engineers reviewing the 1.5SMC200CAHE3/57T datasheet, 1.5SMC200CAHE3/57T pinout, 1.5SMC200CAHE3/57T application, or 1.5SMC200CAHE3/57T equivalent, this device serves as a robust, RoHS-compliant, bidirectional TVS for protecting sensitive signal lines and power rails against lightning-induced transients and inductive switching surges in automotive ECUs, industrial sensors, and telecom interfaces.
Technical Context
The 1.5SMC200CAHE3/57T operates as a bidirectional avalanche diode with symmetrical clamping behavior in both polarities, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at VWM).
Designed for surface-mount assembly on standard PCB copper pads (8.0 mm × 8.0 mm per terminal), it delivers 1500 W transient suppression with <1 ns response time and meets MSL Level 1 (260 °C reflow peak). Junction temperature range spans −65 °C to +150 °C, supporting under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin for protected circuit. |
| VBR (Breakdown Voltage) | 220 V min - Voltage at which device enters avalanche breakdown at 1 mA test current; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | 328 V at 4.6 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines maximum stress on downstream components. |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capability under standardized 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 compliance. |
| ID (Reverse Leakage) | <1 μA at 200 V - Negligible standby current; avoids loading of high-impedance sensor or communication lines. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive and industrial ambient conditions. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; suitable for safety-critical modules. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with no polarity marking (no cathode band). Dimensions: 7.11 mm × 6.22 mm × 2.62 mm (L × W × H); matte tin-plated terminals, J-STD-002 solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode / Cathode (bidirectional) | Either terminal functions identically; symmetrical structure allows placement without orientation concern on PCB. |
| Terminal 2 | Anode / Cathode (bidirectional) | Paired terminal forms bidirectional clamping path; no DC polarity dependency required in layout. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables robust protection against severe lightning surges (IEC 61000-4-5) and load dump events in automotive power nets. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive electronics including engine control units, ADAS sensors, and body control modules requiring zero-failure field reliability. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients, improving protection margin for 3.3 V/5 V logic and analog front-ends. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning risk during assembly. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage performance across temperature and lifetime, critical for industrial deployments. |
Applications

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 | Same 200 V VWM, but SMB package (smaller footprint, 600 W PPPM rating) | Limited to lower-energy surges (e.g., ESD-only); insufficient for IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is limited to human-body-model ESD. |
| 1.5KE200CA | Through-hole DO-201 package, identical 200 V VWM and 1500 W rating, but no AEC-Q101 qualification | Not approved for automotive use; higher thermal resistance limits sustained surge repetition | Choose only for cost-sensitive industrial prototypes where automotive qualification is not required. |
Compared with SMBJ200CA and 1.5KE200CA, the 1.5SMC200CAHE3/57T uniquely combines SMC surface-mount compatibility, full 1500 W surge capacity, and AEC-Q101 validation-making it the only option qualified for production automotive electronics requiring both high energy handling and zero-defect reliability.

FAQ
What does the "CA" suffix mean in 1.5SMC200CAHE3/57T?
The "CA" suffix in 1.5SMC200CAHE3/57T indicates a bidirectional configuration-meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., "A" suffix), it has no cathode marking and can be mounted without orientation concerns, making it ideal for AC-coupled or differential signal protection such as CAN bus or RS-485 lines. This is confirmed in Vishay's 1.5SMC series documentation.
Is 1.5SMC200CAHE3/57T suitable for automotive applications?
Yes, 1.5SMC200CAHE3/57T is explicitly AEC-Q101 qualified, as indicated by the "HE3" suffix. It has undergone rigorous stress testing-including temperature cycling, highly accelerated life testing (HALT), and ESD validation-to meet automotive reliability standards. Its −65 °C to +150 °C operating range and MSL Level 1 rating further confirm suitability for under-hood and chassis-mounted electronic control units.
What is the clamping voltage of 1.5SMC200CAHE3/57T at its rated peak pulse current?
The 1.5SMC200CAHE3/57T has a maximum clamping voltage (VC) of 328 V at a peak pulse current (IPPM) of 4.6 A, measured under the standard 10/1000 μs waveform. This value is specified in Vishay's official datasheet (Document Number: 88303, page 2) and defines the upper voltage limit imposed on protected circuits during surge events.
How does the SMC (DO-214AB) package of 1.5SMC200CAHE3/57T compare to SMB or SMCJ packages?
The SMC (DO-214AB) package used by 1.5SMC200CAHE3/57T measures 7.11 mm × 6.22 mm × 2.62 mm and supports 1500 W peak pulse power-significantly higher than SMB (600 W) and comparable to SMCJ (1500 W), but with tighter dimensional tolerances and AEC-Q101 qualification. Unlike SMCJ, the 1.5SMC200CAHE3/57T offers automotive-grade reliability in the same footprint, verified in Vishay's mechanical drawings and qualification reports.
Can 1.5SMC200CAHE3/57T replace older through-hole TVS diodes like 1.5KE200CA?
While 1.5SMC200CAHE3/57T shares identical electrical ratings (200 V VWM, 1500 W PPPM) with 1.5KE200CA, it is not a direct drop-in replacement due to its surface-mount SMC package versus through-hole DO-201. However, it offers superior features: AEC-Q101 qualification, MSL Level 1 reflow compatibility, and smaller PCB footprint. Migration requires layout revision but delivers enhanced reliability and manufacturability for new automotive and industrial designs.
