Product details
Overview
P6SMB7.5CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 7.5 V standoff voltage (VWM), 11.3 V maximum clamping voltage at 53.1 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - ideal for protecting MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P6SMB7.5CAHE3_B/H datasheet, P6SMB7.5CAHE3_B/H pinout, P6SMB7.5CAHE3_B/H application, or P6SMB7.5CAHE3_B/H equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, low clamping ratio (VC/VWM = 1.51), MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
The P6SMB7.5CAHE3_B/H operates as a symmetric bidirectional TVS, delivering identical clamping performance in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<500 μA at 6.4 V), while its 100 °C/W junction-to-ambient thermal resistance supports operation up to +150 °C junction temperature under defined PCB copper pad conditions.
It complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and ISO 7637-2 (automotive surge) immunity requirements when applied per recommended layout. The device uses a silicon avalanche structure optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of inductive switching spikes and lightning-induced surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.4 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 7.13–7.88 V at 10 mA - Measured voltage where device enters avalanche; ensures reliable triggering across process variation. |
| VC (Clamping Voltage) | 11.3 V at 53.1 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs transient; determines safe voltage headroom for downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Maximum transient energy absorption capability under standardized 10/1000 μs waveform; enables robust protection against common surge events. |
| ID (Reverse Leakage) | ≤500 μA at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |

| Low clamping ratio (VC/VWM) | 1.77 - Enables tighter voltage margin between protected IC's absolute maximum rating and clamping level, reducing overvoltage risk. |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Digital Input Protection |
|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load-dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt transients before reaching sensitive interface ICs. Use Value: Prevents latch-up or permanent damage to transceivers rated for ≤16 V absolute maximum, leveraging 11.3 V clamping at 53.1 A. |
Use Scenario: Safeguarding 24 V DC digital input channels in programmable logic controllers against field-wiring induced surges and contact bounce. IC Role / Device Role / Timing Role: Primary transient suppressor mounted adjacent to optocoupler input or Schmitt trigger, limiting voltage to safe levels during 1 kV/μs transients. Use Value: Maintains signal integrity during repeated surge exposure with <500 μA leakage at 6.4 V, avoiding false triggering in high-impedance input stages. |
| Consumer Appliance Motor Drive Protection | Telecom Power Rail Clamping |
|
Use Scenario: Suppressing inductive kickback from brushed DC motors in washing machines, HVAC blowers, and power tools. IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals or H-bridge outputs to clamp flyback voltage spikes during PWM commutation. Use Value: Absorbs 600 W peak pulses without degradation, enabling use with 100 A IFSM-rated MOSFETs and eliminating need for snubber RC networks. |
Use Scenario: Clamping overvoltage on 48 V PoE or telecom DC power distribution rails exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Secondary-level protection staged after primary MOV/GDT, providing precise low-voltage clamping for downstream DC/DC converters. Use Value: Delivers 11.3 V clamping at 53.1 A with <1 ns response - faster than MOVs - ensuring clean shutdown of sensitive PMICs before overvoltage lockout triggers. |
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), higher VC (12.0 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients; less suitable for automotive load-dump where 600 W margin is required. | Select P6SMB7.5CAHE3_B/H when 600 W rating, AEC-Q101, or SMB mechanical robustness are mandatory. |
| 1.5SMC7.5CA | Same VWM/VC specs, but larger SMC (DO-214AB) package, higher thermal mass, RθJA ≈ 60 °C/W. | Better sustained power handling but incompatible with dense layouts requiring SMB footprint. | Choose P6SMB7.5CAHE3_B/H for space-constrained boards needing AEC-Q101 compliance and standard SMB reflow profiles. |
Compared with SMAJ7.5CA and 1.5SMC7.5CA, the P6SMB7.5CAHE3_B/H uniquely balances 600 W surge capacity, AEC-Q101 qualification, and SMB footprint - making it optimal for automotive and industrial SMT designs where reliability, size, and standardized assembly converge.

FAQ
What does the "CA" suffix indicate in P6SMB7.5CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration: the P6SMB7.5CAHE3_B/H provides symmetrical clamping in both polarities, with identical breakdown and clamping characteristics regardless of voltage polarity. This eliminates the need for orientation during placement and simplifies design for AC-coupled or differential signal lines, unlike unidirectional variants (e.g., P6SMB7.5A) that require cathode alignment.
Is P6SMB7.5CAHE3_B/H suitable for automotive applications?
Yes - the P6SMB7.5CAHE3_B/H carries AEC-Q101 qualification (denoted by the "HE3_B" suffix), confirming validation for automotive use including temperature cycling, highly accelerated life testing, and ESD robustness. It meets ISO 7637-2 Pulse 1 and Pulse 3a/b requirements when mounted per Vishay's recommended 0.2" × 0.2" copper pads, making it appropriate for engine control units, body modules, and ADAS sensor interfaces.
What is the clamping voltage of P6SMB7.5CAHE3_B/H at its rated peak pulse current?
The P6SMB7.5CAHE3_B/H has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value defines the highest voltage imposed on the protected circuit during worst-case transient events and is critical for ensuring downstream ICs remain within their absolute maximum voltage ratings.
How does the SMB package of P6SMB7.5CAHE3_B/H compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of P6SMB7.5CAHE3_B/H offers a 4.57 mm × 3.94 mm footprint - smaller than SMC (DO-214AB) but larger than SMA (DO-214AC), striking a balance between board area, thermal dissipation (RθJA = 100 °C/W), and mechanical robustness. Unlike SMA, SMB supports higher surge energy (600 W vs. 400 W), and unlike SMC, it maintains compatibility with fine-pitch automated placement equipment used in high-volume automotive PCB assembly.
What is the maximum reverse leakage current for P6SMB7.5CAHE3_B/H at its stand-off voltage?
The P6SMB7.5CAHE3_B/H exhibits a maximum reverse leakage current (ID) of 500 μA at its stand-off voltage (VWM) of 6.4 V, measured at 25 °C. This low leakage ensures minimal impact on high-impedance sensor bias networks or battery-powered circuits, preserving accuracy and extending operational lifetime without introducing parasitic loading effects.
