Product details
Overview
1.5SMC200AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, designed for high-energy surge protection. It features a 171 V standoff voltage (VWM), 200 V breakdown voltage (VBR min), 274 V clamping voltage (VC) at 5.5 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 µs waveform - deployed to safeguard power rails and signal lines in automotive ECUs and industrial motor drives.
For engineers reviewing the 1.5SMC200AHM3/H datasheet, 1.5SMC200AHM3/H pinout, 1.5SMC200AHM3/H application, or 1.5SMC200AHM3/H equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant construction (HM3 suffix), 150 °C maximum junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown to clamp transient overvoltages above its VBR threshold while maintaining low leakage (<1 µA at VWM) under normal operation. Its glass-passivated junction ensures stable performance and reliability across thermal cycles.
The device delivers 1500 W peak pulse power handling per 10/1000 µs waveform with derating above 25 °C ambient, supported by a typical junction-to-lead thermal resistance of 15 °C/W. Polarity is marked by a cathode band, and it meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 170–180 V DC rail protection. |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA test current - Precise avalanche onset range ensuring predictable turn-on during transients. |
| VC (Clamping Voltage) | 274 V at 5.5 A IPPM - Limits downstream voltage stress during 1500 W surge events; critical for MOSFET gate and IC input protection. |
| PPPM (Peak Pulse Power) | 1500 W - Sustains high-energy lightning-induced or inductive-switching surges without failure when mounted on 8 mm × 8 mm copper pads. |
| TJ max | 150 °C - Enables reliable operation in under-hood automotive environments and enclosed industrial enclosures. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with JEDEC-standard pick-and-place equipment. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing per AEC specification. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, unidirectional configuration with cathode indicated by a band on the body. Matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; connected to ground or low-side reference in unidirectional TVS configurations. | Provides return path for surge current; must be routed with low-inductance trace to minimize clamping overshoot. |
| Cathode | Current exit point during reverse-biased clamping; connected to protected line (e.g., 170 V DC bus). | Acts as the protected node interface; polarity marking ensures correct orientation during automated assembly. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) without derating in compact SMC footprint. |
| AEC-Q101 qualified (HM3 suffix) | Validates suitability for automotive powertrain and ADAS modules requiring zero-defect reliability under extended temperature and vibration stress. |
| Halogen-free, RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-1752A material declarations; supports green manufacturing and end-of-life compliance. |
| Low incremental surge resistance | Minimizes VC – VBR differential, reducing voltage overshoot during fast-rising transients (<1 ns response time). |
| MSL Level 1 (260 °C peak) | Allows single-reflow soldering without moisture sensitivity concerns; eliminates bake-out requirement in production. |
Applications
| Automotive Engine Control Unit (ECU) | Industrial Motor Drive DC Bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A-E3/52 | Lower PPPM (600 W), SMB package (smaller footprint), same VWM/VBR range but higher VC (291 V @ 3.4 A). | Not AEC-Q101 qualified; suited for commercial-grade consumer or computing power rails where space is constrained. | Select when board area is limited and surge energy is ≤600 W; verify thermal margin due to higher RθJA (100 °C/W). |
| 1.5KE200A | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 or halogen-free certification; higher mounting inductance. | Used in legacy industrial designs with wave-soldered assemblies; not suitable for high-speed SMT lines or automotive reflow profiles. | Choose only for repair or backward-compatible through-hole upgrades; avoid for new AEC-Q101 or RoHS-halogen-free designs. |
Compared with SMBJ200A-E3/52 and 1.5KE200A, the 1.5SMC200AHM3/H uniquely combines AEC-Q101 qualification, 1500 W surge capacity in SMC form factor, and halogen-free compliance - making it the only option meeting full automotive production requirements without layout or reliability trade-offs.

FAQ
What is the clamping voltage of the 1.5SMC200AHM3/H at its rated peak pulse current?
The 1.5SMC200AHM3/H has a maximum clamping voltage (VC) of 274 V at 5.5 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured with the device mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per the Vishay datasheet. The 1.5SMC200AHM3/H maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC200AHM3/H qualified for automotive applications?
Yes, the 1.5SMC200AHM3/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's 1.5SMC Series datasheet (Document Number: 88303). It undergoes rigorous stress testing including temperature cycling, high-temperature operating life, and mechanical shock - making the 1.5SMC200AHM3/H suitable for engine control units, ADAS sensors, and other automotive subsystems.
What does the "HM3" suffix indicate in 1.5SMC200AHM3/H?
The "HM3" suffix in 1.5SMC200AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. The "H" indicates packaging in 7-inch tape-and-reel (850 units/reel), and "M3" specifies the halogen-free material set. This distinguishes the 1.5SMC200AHM3/H from commercial-grade M3 or E3 variants lacking automotive qualification.
Can the 1.5SMC200AHM3/H be used in bidirectional configurations?
No, the 1.5SMC200AHM3/H is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). Bidirectional operation requires the "CA" variant (e.g., 1.5SMC200CA). Using the 1.5SMC200AHM3/H in reverse-biased signal paths will result in forward conduction and potential failure; always match polarity to circuit topology.
What is the maximum junction temperature rating for the 1.5SMC200AHM3/H?
The 1.5SMC200AHM3/H has a maximum junction temperature (TJ) rating of +150 °C, enabling operation in high-ambient environments such as under-hood automotive locations or sealed industrial enclosures. Derating of peak pulse power applies above 25 °C ambient, per Figure 2 in the Vishay datasheet - a key design consideration for thermal management of the 1.5SMC200AHM3/H.
