Product details
Overview
P6SMB75CAHE3_B/H 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 clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects signal lines and power rails in automotive sensor units, industrial I/O modules, and telecom interface circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB75CAHE3_B/H datasheet, P6SMB75CAHE3_B/H pinout, P6SMB75CAHE3_B/H application, or P6SMB75CAHE3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time (<1.0 ps), enabling effective suppression of sub-nanosecond ESD events per IEC 61000-4-2.
The P6SMB75CAHE3_B/H delivers 600 W peak pulse power handling under standardized 10/1000 μs surge conditions, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W. It is qualified to AEC-Q101 for automotive use and meets J-STD-020 MSL Level 1 with 260 °C reflow peak temperature tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 75 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 71.3–78.8 V at 1 mA - Measured voltage range where device transitions from high-impedance to low-impedance clamping state. |
| VC (Clamping) | 103 V at IPPM = 5.8 A - Maximum voltage seen across terminals during 10/1000 μs surge; determines protected circuit's overvoltage stress. |
| PPPM | 600 W - Peak transient energy absorption capacity under standardized waveform; enables robust protection against lightning-induced surges. |
| ID (Leakage) | ≤1.0 μA at VWM - Low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance interfaces. |
| TJ max | +150 °C - Maximum junction temperature rating supports operation in under-hood automotive and industrial environments. |
| Package | SMB (DO-214AA) - Surface-mount outline with 0.205" × 0.220" footprint; optimized for automated placement and IPC-compliant reflow. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (positive half-cycle) | Conducts surge current into device during positive voltage excursions; forms symmetrical path with cathode. |
| Cathode | Transient current entry (negative half-cycle) | Conducts surge current into device during negative voltage excursions; enables bidirectional clamping without external polarity management. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control modules and ADAS sensor interfaces requiring long-term reliability under thermal cycling and vibration. |
| 600 W peak pulse power | Supports IEC 61000-4-5 Level 3 (1 kV line-to-line, 2 kV line-to-ground) surge immunity without derating on standard 0.2" × 0.2" copper pads. |
| Glass passivated junction | Ensures stable VBR and low ID over lifetime; eliminates risk of junction degradation from moisture ingress or contamination during reflow or field operation. |
| MSL Level 1 rating | Enables direct placement without dry-packaging or baking; compatible with standard SMT reflow profiles up to 260 °C peak temperature. |
| Bidirectional symmetry | Eliminates need for polarity-aware layout; simplifies PCB design for AC-coupled lines, differential buses (e.g., RS-485), and ungrounded sensor outputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA-T | Same SMB package, 75 V VWM, but rated for 600 W with 8.3 ms sine-wave IFSM = 100 A; lacks AEC-Q101 qualification. | Targeted at commercial/industrial systems without automotive qualification requirements; lower cost for non-automotive BOMs. | Select when AEC-Q101 is not mandated and higher single-pulse surge margin (IFSM) is prioritized over automotive reliability validation. |
| 1.5KE75CA | Through-hole DO-201 package, same 75 V VWM and 103 V VC, but larger footprint and 1.5 kW peak power rating. | Suitable for prototyping, high-energy legacy designs, or where manual assembly or board-level repair is preferred. | Choose when PCB real estate allows through-hole mounting and higher single-event energy absorption (>1.5×) is required beyond 600 W. |
Compared with SMBJ75CA-T and 1.5KE75CA, the P6SMB75CAHE3_B/H uniquely combines AEC-Q101 qualification, SMB surface-mount compatibility, and precise 600 W 10/1000 μs surge rating-making it optimal for volume automotive electronics where qualification, miniaturization, and repeatable SMT yield are critical.

FAQ
What is the clamping voltage of the P6SMB75CAHE3_B/H under a 10/1000 μs surge?
The P6SMB75CAHE3_B/H has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB75CAHE3_B/H maintains this clamping performance across its specified operating temperature range of –65 °C to +150 °C.
Is the P6SMB75CAHE3_B/H qualified for automotive applications?
Yes, the P6SMB75CAHE3_B/H is AEC-Q101 qualified, as indicated by the "HE3" and "_B" suffixes in its ordering code. This qualification confirms its suitability for automotive electronic systems, including engine control units, ADAS sensors, and infotainment interfaces. The P6SMB75CAHE3_B/H undergoes rigorous stress testing for temperature cycling, humidity bias, and mechanical shock per AEC-Q101 requirements.
What does the "CA" suffix mean in P6SMB75CAHE3_B/H?
The "CA" suffix in P6SMB75CAHE3_B/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 P6SMB75CAHE3_B/H has no polarity marking and functions identically regardless of applied voltage polarity-ideal for AC lines, differential buses, and floating signal paths.
What is the maximum junction temperature rating for the P6SMB75CAHE3_B/H?
The P6SMB75CAHE3_B/H has a maximum junction temperature (TJ max) rating of +150 °C, verified per its thermal characterization data. This rating supports reliable operation in under-hood automotive environments and industrial enclosures with elevated ambient temperatures. Derating curves in the datasheet confirm sustained 600 W pulse capability down to TJ = 125 °C with appropriate PCB copper area.
How does the P6SMB75CAHE3_B/H compare to the P6SMB75A variant?
The P6SMB75CAHE3_B/H is the bidirectional version of the series, whereas P6SMB75A is unidirectional and features a cathode band marking. Both share identical VWM (75 V), VC (103 V), and PPPM (600 W), but only the P6SMB75CAHE3_B/H supports symmetrical clamping without polarity constraints. The P6SMB75CAHE3_B/H also carries AEC-Q101 qualification via its HE3_B suffix, which may not apply to all P6SMB75A variants.
