Product details
Overview
1.5SMC200CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 1500 W peak pulse power (10/1000 μs). It clamps transients to ≤274 V at 5.5 A peak pulse current and operates across -65 °C to +150 °C junction temperature - deployed for lightning and inductive-switching surge protection on automotive sensor signal lines.
For engineers reviewing the 1.5SMC200CAHM3/I datasheet, 1.5SMC200CAHM3/I pinout, 1.5SMC200CAHM3/I application, or 1.5SMC200CAHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), halogen-free RoHS compliance, and bidirectional clamping behavior confirmed per Vishay Document 88303.
Technical Context
This device functions as a bidirectional voltage-clamping protector with symmetrical avalanche breakdown in both polarities, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low leakage (<1 μA at VWM), while the SMC package supports automated placement and meets MSL Level 1 reflow standards (260 °C peak).
The 1.5SMC200CAHM3/I delivers 1500 W peak pulse power under standardized 10/1000 μs waveform conditions, with clamping voltage tightly specified at 274 V (max) at IPPM = 5.5 A. Thermal performance is characterized by RθJL = 15 °C/W (junction-to-leads) and RθJA = 75 °C/W (junction-to-ambient on 8 mm × 8 mm copper pads), enabling reliable operation in high-reliability automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown min) | 220 V at IT = 1 mA - Minimum voltage at which avalanche conduction initiates; ensures predictable turn-on during overvoltage events. |
| VC (Clamping max) | 274 V at IPPM = 5.5 A - Maximum voltage seen by protected circuit during 1500 W transient; determines stress on downstream components. |
| PPPM | 1500 W (10/1000 μs) - Peak transient energy absorption capability; validates suitability for IEC 61000-4-5 Level 4 surge testing. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive locations with high ambient thermal loads. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 8 mm × 8 mm copper pads; informs PCB thermal layout requirements. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, and ESD testing; designated by HM3 suffix. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal pair | No functional distinction - either terminal serves as anode or cathode depending on transient polarity; enables single-component protection of AC or differential lines. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled, differential, or floating signal paths without polarity constraints. |

| Halogen-free & RoHS-compliant | Meets global environmental regulations and supports lead-free reflow assembly (MSL Level 1, 260 °C peak). |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD or inductive kickback). |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) in engine bay modules exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt transients before reaching PHY or ADC front-end. Use Value: Maintains signal integrity under 100 V/10 ms load dump events while surviving >1000 surge cycles due to low clamping ratio (VC/VWM = 1.37). |
Use Scenario: Guarding differential CAN_H/CAN_L lines against ESD (IEC 61000-4-2 ±8 kV contact) and burst noise in factory automation gateways. IC Role / Device Role / Timing Role: Common-mode TVS pair (one per line) or single bidirectional device across differential pair to suppress asymmetric surges. Use Value: Limits voltage excursion to ≤274 V during 5.5 A transient, preserving CAN transceiver common-mode range and preventing bus lockup. |
| Telecom Power Input Stage | Consumer Appliance Motor Control |
Use Scenario: Safeguarding 24 V DC input rails of PoE-powered network switches and base station RF modules against lightning-induced surges. IC Role / Device Role / Timing Role: Primary-stage TVS mounted upstream of DC-DC converter input to absorb bulk surge energy before regulation stage. Use Value: Handles 1500 W peak power without degradation, reducing need for secondary protection and simplifying BOM. |
Use Scenario: Shielding microcontroller GPIOs and gate drivers in washing machine motor inverters from commutation spikes generated by BLDC motors. IC Role / Device Role / Timing Role: Localized TVS at MCU I/O pins and half-bridge driver outputs to clamp sub-100 ns switching transients. Use Value: Fast response time (<1 ns) and low clamping voltage prevent latch-up or permanent damage to 3.3 V logic interfaces. |
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/VBR, SMB package (smaller footprint, higher RθJA = 90 °C/W) | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for IEC 61000-4-5 surge | Select when space-constrained layouts prioritize size over surge rating, and transient energy is <600 W. |
| 1.5KE200CA | Through-hole DO-201 package, identical VWM/VBR/PPPM, but incompatible with SMT assembly and higher thermal resistance | Requires manual or wave soldering; not viable for automated high-volume production or compact PCBs | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ200CA and 1.5KE200CA, the 1.5SMC200CAHM3/I uniquely combines 1500 W surge capability, SMT compatibility, AEC-Q101 qualification, and halogen-free construction - making it the only option meeting automotive production, high-reliability industrial, and RoHS+REACH compliance simultaneously.

FAQ
What does the "HM3" suffix indicate in 1.5SMC200CAHM3/I?
The "HM3" suffix in 1.5SMC200CAHM3/I denotes halogen-free, RoHS-compliant construction with full AEC-Q101 qualification - confirming its suitability for automotive applications including engine control units and ADAS sensors. This distinguishes it from commercial-grade M3 or E3 variants and validates reliability under extended temperature cycling and humidity testing.
Is 1.5SMC200CAHM3/I unidirectional or bidirectional?
The 1.5SMC200CAHM3/I is a bidirectional TVS diode, as confirmed by the "CA" suffix and absence of polarity marking. It provides symmetrical clamping for both positive and negative transients, making it ideal for protecting AC-coupled lines, differential buses like CAN or RS-485, and floating sensor interfaces without requiring orientation during placement.
What is the maximum clamping voltage for 1.5SMC200CAHM3/I at rated peak pulse current?
The maximum clamping voltage (VC) for 1.5SMC200CAHM3/I is 274 V at 5.5 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value is guaranteed per Vishay Document 88303 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Does 1.5SMC200CAHM3/I meet automotive qualification standards?
Yes, 1.5SMC200CAHM3/I is AEC-Q101 qualified, as explicitly stated in Vishay's ordering information and mechanical data sections. The "HM3" suffix certifies compliance with automotive stress tests including high-temperature operating life, temperature cycling, and ESD - enabling use in safety-critical vehicle subsystems.
What is the thermal resistance of 1.5SMC200CAHM3/I, and how does it affect PCB layout?
The 1.5SMC200CAHM3/I 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. This requires adequate copper pour area and thermal vias beneath the SMC package to maintain TJ ≤ 150 °C under sustained power dissipation, especially in enclosed automotive enclosures.
