Product details
Overview
P6SMB200AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 200 V standoff voltage (VWM), 210 V maximum breakdown voltage (VBR), and 274 V clamping voltage (VC) at 2.2 A peak pulse current (IPPM). It delivers 600 W peak pulse power (10/1000 μs waveform) and is AEC-Q101 qualified for automotive electronics.
For engineers reviewing the P6SMB200AHE3_B/H datasheet, P6SMB200AHE3_B/H pinout, P6SMB200AHE3_B/H application, or P6SMB200AHE3_B/H equivalent, this part supports robust overvoltage protection in automotive power rails, industrial sensor interfaces, and DC bus lines where fast response (<1 ns), low clamping ratio, and reliable AEC-Q101 compliance are required.
Technical Context
The P6SMB200AHE3_B/H operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve stable reverse breakdown and low incremental surge resistance. Its 200 V stand-off voltage enables use on 180–200 V DC systems, while its 274 V clamping voltage limits transient overshoot under 600 W surge conditions.
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation up to TJ = +150 °C. The device meets J-STD-020 MSL Level 1 and is rated for 100 A non-repetitive forward surge current (IFSM), making it suitable for high-energy inductive switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for protected circuit DC bias. |
| VBR (Breakdown) | 190–210 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping) | 274 V at IPPM = 2.2 A - Peak voltage seen by downstream circuit during 600 W 10/1000 μs surge; defines worst-case stress level. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 μs waveform; validates suitability for IEC 61000-4-5 Level 4 surges. |
| IFSM | 100 A - Single half-sine surge rating (8.3 ms); supports protection against motor commutation or relay coil energy release. |
| TJ max | +150 °C - Maximum junction temperature; enables deployment in under-hood automotive environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated SMT placement and reflow. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to system ground or low-side reference in TVS configuration. | Provides return path for clamped surge current; must be routed with low-inductance connection to minimize voltage overshoot. |
| Cathode | Protected line connection point; marked with band on body. | Connected to the line being protected (e.g., 200 V rail); avalanche conduction occurs from cathode to anode during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - enables use in engine control units and ADAS power supplies. |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 surge immunity up to Level 4 (4 kV line-to-ground) without derating in standard PCB layout. |
| Glass passivated junction | Ensures stable VBR over lifetime and improved moisture resistance vs. epoxy-passivated alternatives - critical for long-term field reliability. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without pre-baking - reduces manufacturing complexity and cost. |
| Low clamping ratio (VC/VBR ≈ 1.30) | Minimizes voltage overshoot during clamping - protects sensitive 200 V-rated MOSFETs and gate drivers from overstress. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 190–200 V DC battery-fed subsystems (e.g., HVAC actuators, lighting modules) from load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp positive-going surges within 1 ns. Use Value: Limits transient voltage to ≤274 V, preventing damage to 300 V-rated power FETs and maintaining ASIL-B functional safety integrity. |
Use Scenario: Safeguarding analog input lines of 4–20 mA current-loop sensors in factory automation PLCs exposed to cable-induced lightning surges. IC Role / Device Role / Timing Role: Standoff-connected TVS on signal line to ground, absorbing common-mode transients before they reach precision ADC front-end. Use Value: Maintains signal integrity by limiting induced voltage to <274 V while preserving <1 μA leakage at 200 V - avoids baseline shift in measurement circuits. |
| DC Bus Overvoltage Clamping | Telecom Power Supply Input Protection |
Use Scenario: Clamping voltage spikes on 200 V DC bus in solar microinverters during rapid MPPT transitions or grid fault recovery. IC Role / Device Role / Timing Role: Parallel-connected TVS across bus capacitor to absorb stored energy during overvoltage events. Use Value: Dissipates up to 600 W for 1 ms without thermal runaway, enabling compliance with UL 1741 SA anti-islanding surge requirements. |
Use Scenario: Front-end protection of -48 V telecom rectifier outputs against accidental polarity reversal and AC line coupling surges. IC Role / Device Role / Timing Role: Unidirectional TVS configured with cathode to output rail to block reverse polarity while clamping positive surges. Use Value: Withstands 100 A IFSM and maintains VWM = 200 V - provides dual-layer defense against both miswiring and lightning-induced transients. |
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-E3/52 | Same VWM (200 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 150 °C/W). | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select only when board space is constrained and surge energy is ≤400 W; verify thermal margin at full load. |
| 1.5SMC200A | Same VWM (200 V), identical PPPM (600 W), but SMC (DO-214AB) package - 7.11 mm × 6.22 mm, ~2.5× larger footprint. | Better thermal dissipation (RθJA ≈ 60 °C/W) but incompatible with SMB-reflow layouts and dense automotive PCBs. | Choose when thermal management is primary concern and board area permits larger package; not drop-in replaceable. |
Compared with SMAJ200A-E3/52 and 1.5SMC200A, the P6SMB200AHE3_B/H uniquely balances 600 W surge capability, AEC-Q101 qualification, and SMB footprint - making it the only option meeting automotive Grade 3 surge immunity in space-constrained designs.

FAQ
What is the clamping voltage of the P6SMB200AHE3_B/H at its rated peak pulse current?
The P6SMB200AHE3_B/H has a maximum clamping voltage (VC) of 274 V at its specified peak pulse current (IPPM) of 2.2 A, measured using a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a 600 W transient event and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2.
Is the P6SMB200AHE3_B/H suitable for automotive applications?
Yes, the P6SMB200AHE3_B/H is AEC-Q101 qualified, as indicated by the "HE3_B" suffix per Vishay's ordering nomenclature. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification - making it approved for under-hood and chassis-mounted automotive systems per the P6SMB Series datasheet section "MECHANICAL DATA".
What does the "_B/H" suffix mean in P6SMB200AHE3_B/H?
In P6SMB200AHE3_B/H, "HE3" denotes RoHS-compliant and AEC-Q101 qualified construction, "B" indicates AEC-Q101 qualification level for P6SMB6.8A–P6SMB220A devices, and "H" specifies packaging in 7″ diameter plastic tape and reel with 750 units per reel - per Vishay's Ordering Information table on page 3 of document 88370.
How does the thermal resistance of the P6SMB200AHE3_B/H affect PCB layout?
The P6SMB200AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, meaning copper pad area directly impacts safe power dissipation. Vishay specifies mounting on 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated performance; reducing pad size increases junction temperature and may require derating of PPPM in sustained surge conditions.
Can the P6SMB200AHE3_B/H be used in bidirectional configurations?
No, the P6SMB200AHE3_B/H is a unidirectional TVS diode, as confirmed by its part number ending in "A" (not "CA") and its cathode band marking. Bidirectional variants such as P6SMB200CA exist in the same series but have different breakdown symmetry and no polarity marking - using P6SMB200AHE3_B/H in bidirectional roles would result in forward conduction during negative transients.
