Product details
Overview
P6SMB7.5CAHE3_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 clamping voltage of 12.0 V at 53.1 A peak pulse current. It protects signal lines and ICs in automotive sensor units and industrial control interfaces against ESD and inductive switching transients.
For engineers reviewing the P6SMB7.5CAHE3_B/I datasheet, P6SMB7.5CAHE3_B/I pinout, P6SMB7.5CAHE3_B/I application, or P6SMB7.5CAHE3_B/I equivalent, this AEC-Q101 qualified TVS offers verified bidirectional clamping, low thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin terminations suitable for automated SMT assembly and high-reliability automotive designs.
Technical Context
The P6SMB7.5CAHE3_B/I operates as a symmetrical avalanche diode with identical forward and reverse breakdown characteristics, enabling bidirectional transient suppression without polarity sensitivity. Its glass-passivated junction ensures stable VBR (7.13–7.88 V at 10 mA) and low incremental surge resistance across temperature.
Designed for surface-mount PCB integration, it uses SMB (DO-214AA) package geometry with 0.2" × 0.2" copper pad layout per terminal to sustain 600 W peak pulse power under JEDEC-standard 10/1000 μs waveform at 0.01% duty cycle. Junction temperature range spans −65 °C to +150 °C, supporting under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.40 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below circuit supply rails. |
| VBR (Breakdown Voltage) | 7.13–7.88 V at 10 mA - Confirmed avalanche onset range; ensures predictable turn-on during fast transients. |
| VC (Clamping Voltage) | 12.0 V at IPPM = 53.1 A - Peak voltage seen by protected circuit during 600 W transient; limits stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Sustains high-energy surges common in automotive load-dump and inductive switch-off events. |
| ID (Reverse Leakage) | 500 μA max at VWM - Low leakage preserves signal integrity and battery life in always-on sensor circuits. |
| TJ max | +150 °C - Enables operation in engine-control modules and powertrain ECUs without derating. |
| RθJL | 20 °C/W - Low junction-to-lead thermal resistance supports reliable power dissipation without external heatsinking. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional device with no polarity marking; molded compound meets UL 94 V-0; matte tin plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | Accepts surge current in either direction; connects to protected line without polarity constraint. |
| Cathode | Transient current exit (bidirectional) | Completes low-impedance path to ground or reference rail during both positive and negative transients. |
Key Features

Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and alternator ripple in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and chassis ground, absorbing transients before they reach sensitive input stages. Use Value: Maintains signal fidelity under ISO 16750-2 12 V system surges up to +100 V/100 ms while preserving <500 μA leakage at 6.4 V nominal. |
Use Scenario: Shielding 24 V DC digital inputs on programmable logic controllers from relay coil flyback and field-wiring ESD events. IC Role / Device Role / Timing Role: Fast-response shunt protector mounted directly at connector entry point, limiting transient voltage to ≤12.0 V within nanoseconds. Use Value: Prevents false triggering and latch-up in optocoupler input stages during 600 W inductive spikes, extending system uptime. |
| Consumer Appliance Motor Control | Telecom Line Card Surge Protection |
|
Use Scenario: Safeguarding microcontroller GPIOs driving brushed DC motors in smart home appliances subject to commutation noise. IC Role / Device Role / Timing Role: Low-capacitance (≈100 pF at 0 V) bidirectional clamp across motor driver output and MCU input pins. Use Value: Clamps 10/1000 μs transients to 12.0 V without distorting PWM signals or inducing ground bounce in mixed-signal layouts. |
Use Scenario: Front-end protection for Ethernet PHYs and PoE injectors exposed to lightning-induced surges on RJ45 ports. IC Role / Device Role / Timing Role: Primary-level TVS on differential pairs, coordinated with GDTs and common-mode chokes per IEC 61000-4-5. Use Value: Limits common-mode surge voltage to <12.0 V before secondary protection activates, reducing stress on integrated Ethernet magnetics. |
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), lower PPPM (400 W), SMA package (higher RθJA = 150 °C/W). | Limited to lower-energy transients; less suitable for automotive load-dump where 600 W is required. | Select when board space is constrained and surge energy remains ≤400 W. |
| 1.5SMC7.5CA | Same VWM (6.4 V), same PPPM (600 W), but larger SMC (DO-214AB) package (3.5 mm width vs. SMB's 2.6 mm). | Requires larger PCB footprint; better thermal mass but incompatible with dense automotive modules. | Choose only if higher thermal mass is prioritized over miniaturization and AEC-Q101 compliance is not mandatory. |
Compared with SMAJ7.5CA and 1.5SMC7.5CA, the P6SMB7.5CAHE3_B/I uniquely combines AEC-Q101 qualification, SMB footprint, and 600 W capability-making it the only option validated for space-constrained, high-reliability automotive signal line protection.

FAQ
What does the "CA" suffix indicate in P6SMB7.5CAHE3_B/I?
The "CA" suffix denotes a bidirectional configuration: the P6SMB7.5CAHE3_B/I functions identically in both polarities, with symmetric breakdown and clamping behavior. This eliminates polarity concerns during PCB layout and enables protection of AC-coupled or differential signal lines without orientation constraints-unlike unidirectional variants (e.g., P6SMB7.5A) that require cathode alignment.
Is P6SMB7.5CAHE3_B/I suitable for automotive applications?
Yes, the P6SMB7.5CAHE3_B/I is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3_B" suffix. It meets stress test requirements for temperature cycling, highly accelerated life testing, and ESD immunity, and is rated for operation from −65 °C to +150 °C-making it appropriate for engine control units, body electronics, and ADAS sensor modules.
What is the maximum clamping voltage of P6SMB7.5CAHE3_B/I under surge conditions?
The P6SMB7.5CAHE3_B/I clamps to a maximum of 12.0 V when subjected to its rated peak pulse current of 53.1 A (10/1000 μs waveform). This value is measured per JEDEC standards and guarantees that protected circuitry sees no more than 12.0 V during worst-case transients-critical for safeguarding 5 V and 3.3 V logic interfaces.
How does the SMB (DO-214AA) package of P6SMB7.5CAHE3_B/I compare to SMA or SMC alternatives?
The SMB package of P6SMB7.5CAHE3_B/I measures 3.94 mm × 2.20 mm × 1.52 mm-smaller than SMC (DO-214AB) and slightly larger than SMA (DO-214AC). Its 20 °C/W junction-to-lead thermal resistance enables efficient heat transfer to PCB copper, while maintaining compatibility with standard 7" and 13" tape-and-reel automation equipment used in high-volume automotive manufacturing.
Does P6SMB7.5CAHE3_B/I require special PCB layout considerations?
Yes-the P6SMB7.5CAHE3_B/I requires minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve its rated 600 W peak pulse power. Short, direct traces to ground or reference planes are essential; avoid vias or narrow traces between the device and protection target. The absence of polarity marking means layout symmetry is acceptable, but thermal relief must be minimized to preserve RθJL performance.
