Product details
Overview
P6SMB7.5CAHM3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 7.5 V standoff voltage (VWM), and 11.3 V clamping voltage (VC) at 53.1 A peak pulse current - deployed for ESD and surge protection on low-voltage signal lines in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6SMB7.5CAHM3_B/I datasheet, P6SMB7.5CAHM3_B/I pinout, P6SMB7.5CAHM3_B/I application, or P6SMB7.5CAHM3_B/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding its 7.13–7.88 V breakdown range (VBR at 10 mA), it avalanches symmetrically in both directions to limit voltage across protected circuitry. Its glass-passivated junction ensures stable leakage (<500 μA at VWM) and fast response (<1 ns).
Designed for repetitive surge events at 0.01% duty cycle, the P6SMB7.5CAHM3_B/I delivers 11.3 V clamping at 53.1 A (10/1000 μs), with thermal resistance RθJA = 100 °C/W and maximum junction temperature of +150 °C - enabling use in compact, unheatsinked PCB layouts where transient energy is limited to ≤600 W per event.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.40 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 7.13–7.88 V at 10 mA - Symmetrical avalanche initiation point in both directions; ensures consistent turn-on behavior. |
| VC (Clamping Voltage) | 11.3 V at IPPM = 53.1 A - Peak voltage seen by protected IC during worst-case 10/1000 μs surge; determines safe headroom for downstream logic. |
| PPPM (Peak Pulse Power) | 600 W - Maximum single-event transient energy absorption capability under standardized 10/1000 μs waveform. |
| ID (Reverse Leakage) | ≤500 μA at 6.40 V - Low standby current preserves signal integrity and battery life in always-on sensor circuits. |
| TJ max. | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures without forced cooling. |
| MSL Level | Level 1 (J-STD-020) - Supports standard reflow profiles up to 260 °C peak without baking or special handling. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Bidirectional construction has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Identical terminals; bidirectional clamping allows connection across any two-point signal line without orientation concern. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, ADAS sensors, and infotainment I/O. |
| 600 W peak pulse rating | Handles high-energy transients from inductive switching (e.g., solenoid drivers) without degradation over 1000+ events at 0.01% duty cycle. |
| Low clamping ratio (VC/VBR ≈ 1.49) | Minimizes overvoltage stress on protected ICs - critical for 3.3 V and 5 V logic rails where margin is tight. |
| MSL Level 1 rating | Eliminates pre-bake requirements and supports standard SMT reflow, reducing manufacturing cost and process complexity. |
| Glass-passivated junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure - essential for 10+ year field life. |
Applications
| Automotive Sensor Interface | Industrial PLC Digital Input |
|---|---|

Use Scenario: Safeguarding 24 V digital input channels on programmable logic controllers against field-wiring surges and relay contact bounce. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing induced spikes before they reach optocoupler input stages or microcontroller GPIOs. Use Value: Clamps to 11.3 V within nanoseconds, preventing false triggering and latch-up in 3.3 V/5 V logic interfaces powered from isolated 24 V supplies. |
| Consumer IoT Power Supply Rail | Telecom Line Card Protection |
|
Use Scenario: Guarding USB-C PD negotiation lines and auxiliary power rails in smart home hubs against ESD and hot-swap transients. IC Role / Device Role / Timing Role: Low-capacitance bidirectional suppressor placed adjacent to USB controller pins to minimize signal distortion. Use Value: Delivers <500 μA leakage at 6.4 V and sub-1 ns response - preserving data integrity on high-speed control lines without loading. |
Use Scenario: Shielding Ethernet PHY interface lines and auxiliary management buses (e.g., I²C, SPI) in carrier-grade line cards from lightning-induced surges. IC Role / Device Role / Timing Role: First-line defense mounted at board edge, working in coordination with GDTs and common-mode chokes. Use Value: Provides precise 7.5 V standoff and 11.3 V clamping to protect 3.3 V PHYs while surviving repeated 600 W pulses per GR-1089 compliance tests. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5CA | Same VWM (6.4 V), VC = 12.0 V at 49.2 A; lower PPPM (400 W); SMA package (larger footprint, higher RθJA). | Less robust for high-energy surges; suited for space-constrained consumer boards where 400 W suffices. | Select when cost or legacy layout favors SMA, but verify thermal derating for >100 kHz surge repetition. |
| 1.5SMC7.5CA | Same VWM/VC specs; higher PPPM (1500 W); larger SMC package; RθJA = 30 °C/W. | Overqualified for low-energy threats; requires more PCB area and may be overkill for sensor-level protection. | Choose only if system-level testing demands >600 W margin or if existing SMC footprints are fixed. |
Compared with SMAJ7.5CA and 1.5SMC7.5CA, the P6SMB7.5CAHM3_B/I uniquely balances AEC-Q101 qualification, SMB footprint efficiency, and 600 W capability - making it optimal for automotive and industrial designs requiring validated reliability in minimal board area.

What is the maximum clamping voltage of P6SMB7.5CAHM3_B/I under surge conditions?
The P6SMB7.5CAHM3_B/I clamps to a maximum of 11.3 V when subjected to its rated peak pulse current of 53.1 A (10/1000 μs waveform), providing predictable overvoltage limiting for 3.3 V and 5 V logic rails while maintaining safe margin below IC absolute maximum ratings.
How does the "HM3_B/I" ordering code affect P6SMB7.5CAHM3_B/I packaging and handling?
The "HM3_B/I" suffix specifies halogen-free, RoHS-compliant construction (HM3), AEC-Q101 qualification (B), and 13-inch tape-and-reel packaging (I) with 3200 units per reel - ensuring compatibility with high-volume SMT lines and adherence to automotive environmental and traceability requirements.
Can P6SMB7.5CAHM3_B/I replace older P6SMB7.5CA-E3 parts in existing designs?
Yes, the P6SMB7.5CAHM3_B/I maintains identical electrical specifications (VWM, VBR, VC, PPPM) and SMB (DO-214AA) mechanical outline as P6SMB7.5CA-E3, with added AEC-Q101 qualification and halogen-free materials - allowing drop-in replacement where enhanced reliability or compliance is required.
