Product details
Overview
P6SMB75CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 75 V standoff voltage (VWM), 103 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects sensitive signal lines and power rails in automotive and industrial electronics against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the P6SMB75CAHE3/52 datasheet, P6SMB75CAHE3/52 pinout, P6SMB75CAHE3/52 application, or P6SMB75CAHE3/52 equivalent, this device is selected for robust bidirectional overvoltage protection where AEC-Q101 qualification, low clamping ratio (1.37×VWM), and MSL Level 1 reflow compatibility are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 71.3–78.8 V (min/max) under 1 mA test current. Its clamping behavior is characterized by low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of transient energy before downstream components experience overstress.
The device is thermally rated for junction temperatures up to +150 °C, with thermal resistance from junction-to-ambient (RθJA) of 100 °C/W on standard 0.2" × 0.2" copper pads. It meets JESD201 Class 2 whisker resistance and is RoHS-compliant with matte tin-plated leads solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 64.1 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VC @ IPPM | 103 V at 5.8 A - Clamped voltage during 10/1000 μs surge; limits stress on protected ICs or MOSFETs. |
| PPPM | 600 W - Peak pulse power handling capability; determines survivability against standardized lightning/surge events. |
| IPPM | 5.8 A - Peak pulse current corresponding to VC; used to size PCB trace width and verify system-level surge compliance. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments. |
| MSL Level | Level 1 (J-STD-020) - No floor life limitation; allows unlimited exposure to ambient conditions prior to reflow. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |

IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential signal pair or supply-to-ground to clamp transients before reaching ADC input or op-amp front-end. Use Value: Prevents sensor signal corruption and microcontroller reset events caused by >100 V spikes, leveraging 64.1 V VWM headroom and 103 V clamping. |
Use Scenario: Safeguarding CANH/CANL lines in vehicle body control units against ESD and coupled noise from nearby solenoid drivers. IC Role / Device Role / Timing Role: Low-capacitance bidirectional suppressor installed as common-mode clamp between CANH–CANL and chassis ground. Use Value: Maintains CAN signal integrity up to 1 Mbps by limiting transient-induced common-mode offset to <103 V without adding timing skew. |
| Telecom Power Rail Clamp | Consumer USB Port ESD Protection |
Use Scenario: Secondary-side overvoltage protection on 48 V telecom DC-DC converter outputs feeding PoE-powered equipment. IC Role / Device Role / Timing Role: Standoff-rated TVS connected between output rail and ground to absorb residual surge energy after primary-stage MOV suppression. Use Value: Provides precise 64.1 V clamping threshold aligned with 48 V nominal rail tolerance, avoiding false triggering while ensuring sub-103 V stress on downstream regulators. |
Use Scenario: Board-level ESD protection for USB 2.0 data lines (D+/D−) in smart home hubs and set-top boxes. IC Role / Device Role / Timing Role: Bidirectional suppressor placed differentially across D+/D− to shunt ±15 kV contact discharge energy per IEC 61000-4-2. Use Value: Achieves <0.5 pF typical junction capacitance (per Vishay P6SMB series curves), preserving signal rise/fall times without degrading eye diagram integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75CA | Same VWM (64.1 V), lower PPPM (400 W), SMA package (larger footprint, higher RθJA). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 3 compliance. | Select when cost sensitivity outweighs surge rating and board space permits larger SMA footprint. |
| SMCJ75CA | Same VWM, higher PPPM (1500 W), SMC package (3.5 mm × 7.0 mm vs. SMB's 3.94 mm × 2.20 mm). | Overqualified for most 600 W use cases; adds unnecessary height and layout area. | Choose only when system-level surge testing exceeds 600 W or long-term derating margin is critical. |
Compared with SMAJ75CA and SMCJ75CA, P6SMB75CAHE3/52 delivers optimal balance of AEC-Q101 qualification, 600 W surge capacity, and compact SMB footprint-making it the preferred choice for space-constrained automotive and industrial PCBs requiring validated reliability and precise clamping.

FAQ
What does the "CA" suffix indicate in P6SMB75CAHE3/52?
The "CA" suffix denotes a bidirectional configuration: P6SMB75CAHE3/52 provides symmetrical transient suppression for both positive and negative voltage excursions, unlike unidirectional variants (e.g., P6SMB75A). This eliminates polarity concerns during placement and enables protection of AC-coupled or floating circuits without external diode pairing. The device achieves this via a back-to-back PN junction structure internal to the SMB package.
Is P6SMB75CAHE3/52 suitable for IEC 61000-4-5 surge testing?
Yes, P6SMB75CAHE3/52 is rated for 600 W peak pulse power with a 10/1000 μs waveform, meeting IEC 61000-4-5 Level 3 (1 kV line-to-line, 2 kV line-to-earth) requirements when properly mounted on 0.2" × 0.2" copper pads. Its 103 V clamping voltage at 5.8 A ensures protected circuitry remains within safe operating limits during standardized surge events, provided layout minimizes parasitic inductance.
How does the HE3 suffix affect P6SMB75CAHE3/52's qualification status?
The HE3 suffix indicates RoHS-compliant construction and full AEC-Q101 qualification, including stress tests for temperature cycling, high-temperature reverse bias (HTRB), and ESD (HBM ≥ 8 kV, CDM ≥ 1 kV). This distinguishes it from commercial-grade E3 variants and validates its use in automotive powertrain, chassis, and ADAS modules where long-term reliability under thermal and mechanical stress is mandatory.
What is the thermal resistance of P6SMB75CAHE3/52, and how does it impact layout?
P6SMB75CAHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. To maintain TJ ≤ 150 °C under sustained 5.0 W power dissipation, designers must ensure adequate copper area and avoid thermal bottlenecks-such as narrow traces or insufficient vias-to the inner ground/power planes. Derating above 25 °C ambient is required per Figure 2 in the datasheet.
Can P6SMB75CAHE3/52 be used in place of a unidirectional TVS like P6SMB75A?
No-P6SMB75CAHE3/52 is electrically and physically incompatible with unidirectional replacements. Its bidirectional structure lacks cathode marking and conducts equally in both directions, whereas P6SMB75A requires correct polarity orientation and clamps only in reverse bias. Substituting one for the other risks improper transient shunting, increased leakage, or failure to protect during positive-going surges on unidirectional designs.
