Product details
Overview
P6SMB200A-M3/5B 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 P6SMB200A-M3/5B datasheet, P6SMB200A-M3/5B pinout, P6SMB200A-M3/5B application, or P6SMB200A-M3/5B equivalent, this device delivers 600 W peak pulse power (10/1000 μs), operates from −65 °C to +150 °C, features halogen-free RoHS-compliant construction (M3 suffix), and supports automated SMT placement with MSL Level 1 moisture sensitivity rating.
Technical Context
The P6SMB200A-M3/5B uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance, enabling precise voltage clamping during ESD and surge events. Its unidirectional polarity-marked by a cathode band-ensures asymmetric conduction, blocking reverse voltage up to 200 V while clamping forward surges to ≤274 V.
Thermal performance is defined by RθJA = 100 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W (junction-to-lead), supporting reliable operation under repetitive 0.01% duty cycle pulses. The device meets JESD201 Class 2 whisker resistance and is qualified to AEC-Q101 when ordered with HE3/HM3 suffixes (not applicable to -M3/5B).

Use Value: Enables direct integration without additional series impedance; no signal distortion due to low junction capacitance (<100 pF at 0 V). |
| Telecom AC/DC Adapter Input Stage | Motor Drive Gate Driver Protection |
|
Use Scenario: Secondary-side overvoltage suppression on 48 V telecom rectifier outputs subjected to lightning-induced coupling from primary side. IC Role / Device Role / Timing Role: Parallel-connected TVS across bulk capacitor, triggered only during rare >200 V excursions to avoid steady-state conduction. Use Value: 200 V VWM provides 2× margin over 48 V nominal, while 274 V VC prevents latch-up in downstream PMICs rated for 300 V max. |
Use Scenario: Clamping Miller-induced voltage spikes on high-side gate driver supply rails in 3-phase inverters driving HVAC compressors. IC Role / Device Role / Timing Role: Placed between VDD and GND of isolated gate driver ICs, limiting dv/dt-induced overshoot during IGBT turn-off. Use Value: Fast response (<1 ns) and low dynamic impedance ensure sub-100 ns clamping-critical for preventing false turn-on of power devices. |
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 (200 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy surges (e.g., IEC 61000-4-2 ESD only); unsuitable for IEC 61000-4-5 line surges. | Select when board space is constrained and surge threat level is limited to ±8 kV contact ESD. |
| 1.5SMC200A | Same electrical specs (VWM, VBR, VC), but larger SMC (DO-214AB) package; higher thermal mass and RθJL = 15 °C/W. | Better sustained power handling in high-temperature ambient (>85 °C); requires larger PCB area. | Choose for industrial motor drives where long-duration surge repetition occurs and layout allows 7.11 mm × 6.22 mm footprint. |
Compared with SMAJ200A and 1.5SMC200A, the P6SMB200A-M3/5B uniquely balances 600 W surge capacity, SMB footprint compatibility, and halogen-free compliance-making it optimal for space-constrained, high-reliability 24–48 V systems requiring AEC-Q101-optional qualification paths.

FAQ
What is the clamping voltage of the P6SMB200A-M3/5B at its rated peak pulse current?
The P6SMB200A-M3/5B has a maximum clamping voltage (VC) of 274 V when subjected to its specified peak pulse current (IPPM) of 2.2 A under the standard 10/1000 μs waveform. This value is measured at TA = 25 °C with devices mounted on 0.2" × 0.2" copper pads per terminal, and represents the upper voltage limit imposed on protected circuits during surge events. The P6SMB200A-M3/5B maintains this clamping performance across its full operating temperature range.
Is the P6SMB200A-M3/5B suitable for automotive applications requiring AEC-Q101 qualification?
The P6SMB200A-M3/5B itself is not AEC-Q101 qualified; it carries the M3 suffix indicating halogen-free RoHS compliance for commercial-grade use. For automotive applications requiring AEC-Q101, Vishay offers the P6SMB200AHM3_B variant (with "_B" revision code), which shares identical electrical specs but undergoes additional stress testing. Engineers must specify the HM3_B suffix-not M3/5B-to obtain the qualified version of the P6SMB200A-M3/5B.
What is the reverse leakage current specification for the P6SMB200A-M3/5B at its maximum standoff voltage?
The P6SMB200A-M3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA when biased at its rated stand-off voltage (VWM) of 200 V and tested at TA = 25 °C. This ultra-low leakage ensures minimal power loss in always-on protection configurations and avoids loading sensitive reference or bias networks. The P6SMB200A-M3/5B maintains ID ≤ 5.0 μA up to TJ = 125 °C per Vishay's derating curves.
How does the thermal resistance of the P6SMB200A-M3/5B affect its surge handling capability at elevated ambient temperatures?
The P6SMB200A-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. At ambient temperatures above 25 °C, its peak pulse power rating must be derated per Figure 2 in the datasheet-e.g., at TA = 75 °C, PPPM drops to ~420 W. This derating directly impacts surge survivability in enclosed enclosures or high-temperature industrial environments, and the P6SMB200A-M3/5B must be applied with appropriate thermal margin.
What does the "/5B" suffix indicate in the P6SMB200A-M3/5B part number?
Within the P6SMB200A-M3/5B ordering code, the "/5B" denotes the packaging configuration: 13-inch diameter plastic tape and reel, containing 3200 units per reel. The "M3" prefix specifies halogen-free, RoHS-compliant construction, while "P6SMB200A" identifies the 200 V unidirectional TVS variant. The P6SMB200A-M3/5B is not a functional variant-it is the same electrically and thermally as P6SMB200A-M3/52 (7" reel, 750 units), differing only in reel size and quantity.
