Product details
Overview
P6SMB200AHM3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), and 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), designed to protect power rails and signal lines in industrial power supplies and automotive ECUs against lightning-induced surges and inductive switching transients.
For engineers reviewing the P6SMB200AHM3_B/I datasheet, P6SMB200AHM3_B/I pinout, P6SMB200AHM3_B/I application, or P6SMB200AHM3_B/I equivalent, this device delivers verified 600 W peak pulse power (10/1000 μs), AEC-Q101 qualification for automotive use, halogen-free RoHS compliance, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level surge protection design and long-term supply continuity.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging glass-passivated junction technology for stable reverse leakage (<1.0 μA at 171 V) and fast response time (<1.0 ns). Its thermal resistance (RθJA = 100 °C/W) and junction temperature limit (TJ max = 150 °C) support operation under sustained transient stress when mounted on standard 0.2" × 0.2" copper pads.
The device meets JESD201 Class 2 whisker resistance and solderability per J-STD-002/JESD22-B102. Its 600 W peak pulse rating is defined using the standardized 10/1000 μs waveform, with derating applied above TA = 25 °C per Figure 2 of the datasheet.
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/AC rail margin. |
| VBR (Breakdown Voltage) | 190–210 V at 1.0 mA test current - Voltage at which device enters avalanche conduction; ensures precise overvoltage threshold. |
| VC (Clamping Voltage) | 274 V at IPPM = 2.2 A - Peak voltage seen by protected circuit during surge; determines downstream component voltage stress. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs waveform) - Surge energy handling capacity; validates protection against IEC 61000-4-5 Level 4 transients. |
| ID (Reverse Leakage) | <1.0 μA at VWM - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature; enables reliable operation in under-hood automotive or enclosed industrial enclosures. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" footprint; compatible with automated pick-and-place and reflow. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-indicated by band. Dimensions: 4.57 mm × 3.30 mm × 2.20 mm (L × W × H); matte tin-plated leads, J-STD-002 solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-potential node; completes clamping path during positive transients on cathode side. |
| Cathode | High-side connection point | Connected to protected line (e.g., 24 V rail); conducts avalanche current to anode when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock - suitable for ECU, body control, and ADAS power domains. |
| Halogen-free & RoHS-compliant (HM3 suffix) | Meets global environmental regulations without compromising thermal or electrical performance; supports green manufacturing requirements. |
| 600 W peak pulse power (10/1000 μs) | Provides robust protection against high-energy transients such as ISO 7637-2 pulse 5a/b and IEC 61000-4-5 combination wave surges. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during clamping - reduces stress on downstream MOSFETs, controllers, and interface ICs. |
| MSL Level 1 (260 °C peak reflow) | Enables single-pass lead-free reflow assembly without moisture-related popcorn failure or delamination risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/5B | Same VWM (171 V), lower PPPM (400 W), non-AEC-Q101, RoHS-compliant only (no halogen-free claim) | Limited to commercial-grade industrial equipment; not approved for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom is unnecessary. |
| 1.5SMC200AHE3_A/H | Same VWM/VBR/VC specs, SMC (DO-214AB) package (larger footprint), AEC-Q101 qualified, halogen-free | Requires PCB layout change due to 0.295" × 0.230" footprint vs. SMB's 0.220" × 0.130"; higher thermal mass improves sustained surge handling | Choose when higher thermal dissipation is needed and board space permits larger SMC package. |
Compared with SMAJ200A-E3/5B and 1.5SMC200AHE3_A/H, P6SMB200AHM3_B/I uniquely combines AEC-Q101 qualification, halogen-free compliance, SMB footprint compactness, and full 600 W rating - making it optimal for space-constrained automotive and industrial designs requiring certified reliability and regulatory alignment.

FAQ
What is the clamping voltage of P6SMB200AHM3_B/I at its rated peak pulse current?
The P6SMB200AHM3_B/I has a maximum clamping voltage (VC) of 274 V when subjected to its specified peak pulse current (IPPM) of 2.2 A using the 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance remains stable across temperature and lifetime when operated within rated conditions.
Is P6SMB200AHM3_B/I suitable for automotive applications?
Yes, P6SMB200AHM3_B/I is AEC-Q101 qualified, as indicated by the "HM3_B" suffix per Vishay's ordering nomenclature guide. It undergoes rigorous stress testing including temperature cycling, humidity bias, and mechanical shock, making it suitable for under-hood and chassis-mounted automotive systems such as engine control units, body electronics, and ADAS power domains.
What does the "HM3_B/I" suffix mean in P6SMB200AHM3_B/I?
In P6SMB200AHM3_B/I, "HM3" denotes halogen-free and RoHS-compliant construction; "B" indicates AEC-Q101 qualification for the 6.8 V to 220 V voltage range; and "I" specifies packaging in 13-inch tape-and-reel format with 3200 units per reel. This full suffix confirms environmental compliance, automotive qualification, and logistics configuration for automated assembly.
How does P6SMB200AHM3_B/I compare to bidirectional TVS diodes in the same series?
P6SMB200AHM3_B/I is unidirectional, meaning it protects against positive transients only (cathode-to-anode), unlike bidirectional variants (e.g., P6SMB200CA) that suppress both polarities. Its VWM (171 V) and VBR (190–210 V) apply only in reverse bias; forward conduction follows standard diode behavior. Use P6SMB200AHM3_B/I where polarity is known and ground-referenced protection suffices - reducing cost and simplifying layout versus bidirectional alternatives.
What is the maximum operating junction temperature for P6SMB200AHM3_B/I?
The maximum operating junction temperature (TJ max) for P6SMB200AHM3_B/I is +150 °C, as specified in the Absolute Maximum Ratings table of Vishay document 88370. This rating enables reliable operation in high-ambient environments such as engine compartments or sealed industrial enclosures, provided thermal design accounts for RθJA = 100 °C/W and appropriate copper pad area (0.2" × 0.2") is used per datasheet recommendations.
