Product details
Overview
P6SMB75CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 75 V standoff voltage (VWM), 82.9 V minimum breakdown voltage (VBR), and 103 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPPM). It delivers 600 W peak pulse power (10/1000 μs waveform) and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB75CAHE3_A/H datasheet, P6SMB75CAHE3_A/H pinout, P6SMB75CAHE3_A/H application, or P6SMB75CAHE3_A/H equivalent, this device is selected for robust ESD and surge immunity in high-reliability DC power rails, sensor interfaces, and automotive control modules where bidirectional transient suppression and RoHS-compliant AEC-Q101 qualification are required.
Technical Context
The P6SMB75CAHE3_A/H operates as a bidirectional avalanche diode, symmetrically clamping voltage transients above ±82.9 V in either polarity while maintaining low leakage (<1 μA at 64.1 V). Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns) to ESD and lightning-induced surges.
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it features MSL Level 1 moisture sensitivity, matte tin-plated leads compliant with J-STD-002, and thermal resistance of 100 °C/W (junction-to-ambient) - enabling reliable operation up to 150 °C junction temperature without forced cooling.
Key Specifications

|---|---|
| VWM (Stand-off Voltage) | 64.1 V - Maximum continuous reverse voltage before significant conduction begins; defines safe operating DC bias margin. |
| VBR (Breakdown Voltage) | 71.3–78.8 V at 1 mA - Confirmed avalanche onset range; ensures predictable clamping initiation under transient stress. |
| VC (Clamping Voltage) | 103 V at 5.8 A IPPM - Peak voltage seen by protected circuit during 600 W surge; determines downstream component voltage stress. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Sustains standardized lightning-surge energy without failure; validated per IEC 61000-4-5. |
| TJ max | 150 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
| Package | SMB (DO-214AA) - Industry-standard 2-pin surface-mount outline; compatible with automated pick-and-place and reflow. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package

|---|---|
Use Scenario: Protects microcontroller I/O and LIN bus transceivers from load-dump and jump-start induced transients in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector entry point to clamp ±100 V spikes before reaching signal conditioning circuitry. Use Value: Prevents latch-up or permanent damage to 5 V/3.3 V logic inputs during ISO 16750-2 pulse 5a (35 V, 100 ms) and pulse 5b (−200 V, 100 ms) events. |
Use Scenario: Shields CANH/CANL differential pair from ESD (±8 kV contact) and burst noise in factory automation PLCs. IC Role / Device Role / Timing Role: Low-capacitance bidirectional suppressor placed across differential lines to maintain signal integrity while diverting transients. Use Value: Maintains <1 pF junction capacitance at zero bias (per Fig. 4), avoiding CAN bit timing distortion up to 1 Mbps. |
| Telecom Power Supply Input | Consumer Appliance Motor Driver |
Use Scenario: Guards 48 V DC input stage of PoE-powered network switches against lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary front-end TVS in multi-stage protection scheme, absorbing bulk surge energy before secondary MOV or GDT stages. Use Value: Clamps to ≤103 V within nanoseconds, limiting stress on downstream 60 V-rated MOSFETs and controller ICs. |
Use Scenario: Suppresses inductive kickback from brushed DC motors in smart home appliances (e.g., vacuum cleaners, washing machines). IC Role / Device Role / Timing Role: Bidirectional clamp across motor terminals to quench flyback voltage spikes exceeding 100 V during PWM commutation. Use Value: Enables use of cost-effective 100 V MOSFETs instead of higher-voltage (150 V+) devices, reducing BOM cost and conduction loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | Same VWM (64.1 V), identical SMB package, but rated for 600 W with tighter VBR tolerance (71.3–75.8 V); not AEC-Q101 qualified. | Lacks automotive qualification; suitable for industrial/commercial designs without AEC compliance mandates. | Select SMBJ75CA if AEC-Q101 is unnecessary and tighter VBR distribution improves system margin. |
| 1.5SMC75CA | Higher power rating (1500 W), same VWM and bidirectional function, but larger SMC (DO-214AB) package (4.5 mm × 3.9 mm vs. SMB's 4.1 mm × 2.7 mm). | Requires PCB layout change; preferred where higher surge endurance (e.g., outdoor telecom) outweighs space constraints. | Choose 1.5SMC75CA only when 600 W is insufficient and board area permits larger footprint. |
Compared with SMBJ75CA and 1.5SMC75CA, the P6SMB75CAHE3_A/H uniquely combines AEC-Q101 qualification, SMB footprint, and 600 W capability - making it the optimal choice for space-constrained automotive and industrial applications requiring certified reliability without package redesign.

FAQ
What is the clamping voltage of P6SMB75CAHE3_A/H at its rated peak pulse current?
The P6SMB75CAHE3_A/H has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM), measured under the standard 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 Electrical Characteristics table on page 2 of Vishay document 88370. The P6SMB75CAHE3_A/H maintains this clamping performance across its qualified temperature range.
Is P6SMB75CAHE3_A/H suitable for automotive applications?
Yes, P6SMB75CAHE3_A/H is AEC-Q101 qualified, as indicated by the "HE3" suffix and documented in Vishay's ordering information and mechanical data sections. It undergoes rigorous stress testing including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - making it approved for use in automotive body control modules, infotainment power supplies, and sensor interfaces. The P6SMB75CAHE3_A/H meets all requirements for under-hood and cabin-mounted electronics.
What does the "CA" suffix mean in P6SMB75CAHE3_A/H?
The "CA" suffix in P6SMB75CAHE3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB75A), the CA version has no cathode marking and functions identically in either orientation, simplifying layout for AC-coupled or differential signal lines. This is explicitly stated in the Vishay document under "DEVICES FOR BIDIRECTION APPLICATIONS".
What is the maximum operating temperature for P6SMB75CAHE3_A/H?
The P6SMB75CAHE3_A/H has a maximum junction temperature (TJ max) of +150 °C, as specified in the Maximum Ratings table (page 1). This allows reliable operation in high-ambient environments such as automotive engine compartments or enclosed industrial enclosures. Derating curves in Figure 2 confirm usable power dissipation down to 50% at 125 °C ambient, and the P6SMB75CAHE3_A/H remains functional up to its absolute TJ limit.
How does the SMB package of P6SMB75CAHE3_A/H compare to SMC or DO-214AB?
The P6SMB75CAHE3_A/H uses the SMB (DO-214AA) package - measuring 4.57 mm × 3.94 mm × 2.29 mm - which is significantly smaller than the SMC (DO-214AB) package used by higher-power variants like 1.5SMC75CA. This compact size enables dense PCB layouts while maintaining 600 W surge capability. The P6SMB75CAHE3_A/H's SMB footprint is standardized for automated assembly and requires only 0.2" × 0.2" copper pads per terminal, per Vishay's mounting recommendation.
