Product details
Overview
P6SMB200AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for high-energy surge protection on power and signal lines. It features a 200 V standoff voltage (VWM), 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive-grade industrial power supplies and sensor interface circuits.
For engineers reviewing the P6SMB200AHM3/I datasheet, P6SMB200AHM3/I pinout, P6SMB200AHM3/I application, or P6SMB200AHM3/I equivalent, key selection criteria include its AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, SMB (DO-214AA) package thermal performance, and verified clamping behavior under repetitive transients in 12 V–48 V DC systems.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable breakdown and low incremental surge resistance. Its 100 °C/W junction-to-ambient thermal resistance (RθJA) and 20 °C/W junction-to-lead (RθJL) support reliable operation up to 150 °C junction temperature under transient stress.
The device delivers fast response time (<1 ns) and excellent clamping ratio (VC/VBR ≈ 1.37), validated per IEC 61000-4-5 surge immunity requirements. It is rated for 100 A non-repetitive forward surge current (IFSM) and meets J-STD-020 MSL Level 1 with 260 °C lead-free reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin in 150–200 V rail protection. |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA - Verified avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 274 V at 2.2 A IPPM - Measured peak voltage across device during 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; enables robust lightning/surge immunity. |
| IFSM (Surge Current) | 100 A - Single half-sine 8.3 ms surge rating; supports motor drive and relay coil suppression without failure. |
| TJ max | 150 °C - Maximum junction temperature; allows operation in under-hood automotive and industrial enclosures without derating below 125 °C ambient. |
| Package | SMB (DO-214AA) - Low-profile surface-mount outline with 5.0 mm × 5.0 mm copper pad thermal design; compatible with automated placement and reflow. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward conduction | Connected to lower-potential side of protected line (e.g., ground or return path); defines unidirectional current flow direction. |
| Cathode | Current exit terminal in forward conduction; clamping node in reverse bias | Connected to higher-potential side (e.g., supply rail or signal line); avalanche conduction occurs here during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive applications including engine control units and ADAS sensor interfaces; supports 15-year reliability under thermal cycling and humidity exposure. |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and JEDEC JS709B; eliminates brominated flame retardants while maintaining UL 94 V-0 flammability rating. |
| 600 W peak pulse power (10/1000 μs) | Enables single-device protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) without parallel staging. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD or inductive kickback), improving protection margin for downstream MOSFETs and ICs. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profile use (peak 260 °C) without baking; reduces manufacturing overhead in high-volume SMT lines. |
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 |
|---|---|---|---|
| SMAJ200A | Same VWM (171 V) and VC (274 V), but rated for 400 W PPPM and not AEC-Q101 qualified. | Limited to commercial-grade industrial equipment; lacks automotive qualification and halogen-free certification. | Select when cost sensitivity outweighs automotive compliance and long-term reliability requirements. |
| 1.5SMC200A | Higher package thermal resistance (RθJA = 125 °C/W vs. 100 °C/W); same electrical specs but DO-214AB (SMA) footprint. | Requires PCB layout revision due to larger SMA package; less suitable for dense automotive modules. | Choose only if existing design uses SMA footprint and thermal margin exceeds 25 °C above ambient. |
Compared with SMAJ200A and 1.5SMC200A, P6SMB200AHM3/I provides superior automotive qualification, lower thermal resistance, and halogen-free compliance - making it the preferred choice for new designs targeting AEC-Q101 compliance and high-density SMT layouts.

FAQ
What is the clamping voltage of P6SMB200AHM3/I at its rated peak pulse current?
The P6SMB200AHM3/I has a maximum clamping voltage (VC) of 274 V at 2.2 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured and guaranteed per the Vishay datasheet (Document Number: 88370, Rev. 09-Jan-2024), and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB200AHM3/I maintains this clamping performance across its full operating temperature range (−65 °C to +150 °C).
Is P6SMB200AHM3/I suitable for automotive applications?
Yes, P6SMB200AHM3/I is AEC-Q101 qualified (indicated by the HM3 suffix), fully halogen-free, and RoHS-compliant - meeting stringent automotive reliability requirements for under-hood and body-control module applications. Its construction includes glass-passivated junctions and MSL Level 1 moisture sensitivity, enabling direct use in lead-free reflow processes without baking. The P6SMB200AHM3/I is explicitly listed in Vishay's AEC-Q101 qualified product matrix for the P6SMB family.
What does the "HM3" suffix mean in P6SMB200AHM3/I?
The "HM3" suffix in P6SMB200AHM3/I denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified construction, with "I" indicating 13-inch tape-and-reel packaging (3200 units per reel). This distinguishes it from commercial-grade variants (e.g., "E3" or "M3") and confirms compliance with automotive environmental and reliability standards. The P6SMB200AHM3/I also meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability requirements.
How does P6SMB200AHM3/I compare to P6SMB200AHE3/I in terms of qualification and material content?
P6SMB200AHM3/I is halogen-free and AEC-Q101 qualified, whereas P6SMB200AHE3/I is RoHS-compliant and AEC-Q101 qualified but not halogen-free. Both share identical electrical specifications (VWM = 171 V, VC = 274 V, PPPM = 600 W), SMB package, and 13-inch tape-and-reel format. The P6SMB200AHM3/I satisfies stricter environmental mandates such as JEDEC JS709B and certain Tier 1 automotive OEM material declarations that prohibit brominated flame retardants.
What is the thermal resistance of P6SMB200AHM3/I, and how does it affect PCB layout?
P6SMB200AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal, and junction-to-lead resistance (RθJL) of 20 °C/W. This means effective heat dissipation requires adherence to Vishay's recommended pad layout - undersized pads increase RθJA and risk thermal runaway during repetitive surges. The P6SMB200AHM3/I's low RθJL supports efficient conduction into PCB copper planes, especially critical in high-power industrial drives.
