Product details
Overview
P6SMB75CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal and power lines. It features a 75 V standoff voltage (VWM), 103 V maximum clamping voltage at 5.8 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform. It is AEC-Q101 qualified and housed in an SMB (DO-214AA) package for automotive and industrial surge protection.
For engineers reviewing the P6SMB75CAHE3_A/I datasheet, P6SMB75CAHE3_A/I pinout, P6SMB75CAHE3_A/I application, or P6SMB75CAHE3_A/I equivalent, this device is selected for robust ESD and lightning surge immunity in bidirectional DC bus, sensor interface, and automotive control module designs where low clamping voltage, fast response (<1 ns), and MSL Level 1 reflow compatibility are critical.
Technical Context
The P6SMB75CAHE3_A/I operates as a symmetrical avalanche diode, conducting equally in both directions above its breakdown threshold (VBR min = 71.3 V, max = 78.8 V at 1 mA). Its bidirectional architecture eliminates polarity sensitivity, enabling direct placement across ungrounded differential lines or AC-coupled signals without orientation constraints.
It delivers 600 W transient power handling per the 10/1000 μs standard waveform, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting reliable operation up to TJ = 150 °C. The glass-passivated junction ensures stable leakage (<1 μA at 64.1 V) and long-term reliability under repetitive surge stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 64.1 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 71.3–78.8 V at 1 mA - Voltage at which avalanche conduction initiates; tight tolerance enables predictable turn-on timing. |
| VC (Clamping Voltage) | 103 V at IPPM = 5.8 A - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capability under standardized surge waveform; validates robustness against IEC 61000-4-5 Level 4 events. |
| ID (Reverse Leakage) | <1 μA at 64.1 V - Minimal standby current ensures negligible power loss and signal integrity in high-impedance interfaces. |
| TJ max | 150 °C - Maximum junction temperature rating supports operation in under-hood automotive environments and sealed industrial enclosures. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place and J-STD-020-compliant reflow profiles up to 260 °C peak. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance. Bidirectional construction means no cathode/anode marking - terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode / Cathode (bidirectional) | Either terminal serves as conduction path depending on instantaneous polarity of transient; no fixed polarity assignment. |
| Terminal 2 | Anode / Cathode (bidirectional) | Electrically identical to Terminal 1; forms symmetrical clamping pair across protected line pair or supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled, floating, or differential signal paths without polarity concerns or external biasing. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 combination wave surges (4 kV/2 Ω) without degradation when mounted per recommended 5.0 mm × 5.0 mm copper pads. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces per stress test requirements. |
| Low clamping ratio (VC/VBR ≈ 1.36) | Minimizes overvoltage exposure to downstream ICs - e.g., protects 75 V-rated CAN FD transceivers or 100 V MOSFET gates. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking; simplifies manufacturing logistics for high-volume automotive PCB assembly. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75CA | Same VWM (64.1 V) and VC (103 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive load dump where 600 W is required. | Select P6SMB75CAHE3_A/I when 600 W surge rating and AEC-Q101 qualification are mandatory. |
| SMCJ75CA | Higher PPPM (1500 W), same VWM/VC, but larger SMC (DO-214AB) package; not AEC-Q101 qualified in standard grade. | Over-specified for most 12 V/24 V systems; requires more PCB area and may not meet automotive qualification unless ordered with HE3 suffix. | Choose P6SMB75CAHE3_A/I for space-constrained AEC-Q101-compliant designs needing exact 600 W rating and SMB footprint. |
Compared with SMAJ75CA and SMCJ75CA, the P6SMB75CAHE3_A/I uniquely balances 600 W surge capability, SMB package size, and AEC-Q101 qualification - making it the optimal choice for cost-sensitive, space-limited automotive and industrial modules requiring certified reliability without over-engineering.

FAQ
What does the "CA" suffix indicate in P6SMB75CAHE3_A/I?
The "CA" suffix in P6SMB75CAHE3_A/I denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics regardless of voltage polarity applied across its terminals. This eliminates orientation constraints during PCB layout and enables use on floating or AC-coupled lines without external biasing components.
Is P6SMB75CAHE3_A/I suitable for protecting CAN FD bus lines?
Yes, P6SMB75CAHE3_A/I is suitable for CAN FD bus protection. Its 64.1 V stand-off voltage exceeds the CAN FD common-mode range (±40 V), and its 103 V clamping voltage stays well below the absolute maximum rating of most CAN FD transceivers (typically ±70 V to ±100 V). Its bidirectional nature matches the differential signaling of CAN FD, and AEC-Q101 qualification confirms suitability for automotive network layers.
What is the maximum peak pulse current (IPPM) for P6SMB75CAHE3_A/I?
The maximum peak pulse current (IPPM) for P6SMB75CAHE3_A/I is 5.8 A under the standardized 10/1000 μs double-exponential waveform. This value is derived directly from the device's 600 W peak pulse power rating and 103 V clamping voltage (IPPM = PPPM / VC = 600 W / 103 V ≈ 5.8 A), and is confirmed in the Vishay P6SMB datasheet Table 1 for the P6SMB75CA variant.
Does P6SMB75CAHE3_A/I require a heatsink for normal operation?
No, P6SMB75CAHE3_A/I does not require an external heatsink for transient suppression duty cycles. Its thermal design assumes operation with standard 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, providing sufficient heat dissipation for short-duration surges. Continuous power dissipation is limited to 5.0 W, but typical TVS operation involves only millisecond-scale pulses - making board-level copper thermal mass adequate for all specified surge conditions.
How does the HE3 suffix affect P6SMB75CAHE3_A/I's compliance status?
The HE3 suffix in P6SMB75CAHE3_A/I indicates RoHS-compliant construction with AEC-Q101 qualification - confirming that the device has passed rigorous automotive-grade stress testing including temperature cycling, humidity bias, and accelerated life tests. This distinguishes it from commercial-grade E3 variants and ensures suitability for under-hood and safety-critical vehicle subsystems where reliability validation is mandatory.
