Product details
Overview
P6SMB7.5CAHM3_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 or power lines. It features a 7.5 V standoff voltage (VWM), 11.3 V maximum clamping voltage at 53.1 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform. It is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive-grade reliability.
For engineers reviewing the P6SMB7.5CAHM3_A/I datasheet, P6SMB7.5CAHM3_A/I pinout, P6SMB7.5CAHM3_A/I application, or P6SMB7.5CAHM3_A/I equivalent, key selection considerations include bidirectional transient suppression capability, SMB (DO-214AA) package compatibility, clamping performance under 10/1000 μs surges, and AEC-Q101 qualification status for automotive sensor or ECU protection designs.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 7.13–7.88 V (min/max) at 10 mA test current. Its low clamping ratio (VC/VWM ≈ 1.77) ensures effective overvoltage limiting during fast transients such as ESD or inductive switching spikes.
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation up to +150 °C junction temperature. The device uses glass-passivated silicon junction technology and meets J-STD-020 MSL Level 1 with 260 °C reflow peak, enabling robust automated SMT assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.40 V - Maximum reverse working voltage before clamping begins; defines safe operating range for continuous line bias. |
| VBR (Breakdown Voltage) | 7.13–7.88 V at 10 mA - Voltage at which device transitions into avalanche conduction; tight tolerance supports predictable protection threshold. |
| VC (Clamping Voltage) | 11.3 V at 53.1 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for IC-level overvoltage margining. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy handling per IEC 61000-4-5 waveform; enables robust protection against lightning-induced surges. |
| ID (Reverse Leakage) | 500 μA max at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature rating; supports under-hood automotive environments and industrial enclosures. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" x 0.130" footprint; compatible with automated pick-and-place and reflow processes. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5CA | Same VWM (6.4 V) and VC (11.3 V), but lower PPPM (400 W); SMA package (DO-214AC), smaller footprint. | Limited to lower-energy transients (IEC 61000-4-2 only); unsuitable for ISO 7637-2 pulse 5a load dump simulation. | Select when board space is constrained and surge threat level is limited to ESD-only environments. |
| SMCJ7.5CA | Higher PPPM (1500 W); same VWM/VC specs; larger SMC (DO-214AB) package with higher thermal mass. | Supports harsher automotive load dump and telecom lightning tests; requires larger PCB area and higher assembly cost. | Choose when system-level testing demands >1000 W surge handling and thermal derating margin is critical. |
Compared with SMAJ7.5CA, P6SMB7.5CAHM3_A/I delivers 50 % higher peak pulse power in an SMB footprint, enabling stronger protection without layout redesign; versus SMCJ7.5CA, it trades 2.5× surge capacity for 40 % smaller board area and lower component height-ideal for space-constrained automotive modules.

FAQ
What does the "CA" suffix indicate in P6SMB7.5CAHM3_A/I?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB7.5CAHM3_A/I provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB7.5A), it has no cathode marking and functions identically regardless of terminal orientation-essential for protecting AC-coupled or floating signal paths where polarity is undefined.
Is P6SMB7.5CAHM3_A/I suitable for automotive applications?
Yes, P6SMB7.5CAHM3_A/I is AEC-Q101 qualified and manufactured with HM3 suffix (halogen-free, RoHS-compliant, automotive-grade). It meets stringent automotive reliability requirements including temperature cycling, humidity testing, and mechanical shock-making it appropriate for engine control units, body control modules, and ADAS sensor interfaces where transient immunity and long-term stability are mandatory.
What is the clamping voltage of P6SMB7.5CAHM3_A/I at its rated peak pulse current?
The P6SMB7.5CAHM3_A/I has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current (IPPM), measured using the standard 10/1000 μs double-exponential waveform. This value reflects the worst-case voltage imposed on the protected circuit during a full-rated surge event and is critical for ensuring downstream ICs remain within their absolute maximum ratings.
How does the SMB package of P6SMB7.5CAHM3_A/I compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of P6SMB7.5CAHM3_A/I offers a balance of surge capability and board space efficiency: it delivers 600 W peak power in a 0.220" × 0.130" footprint-smaller than SMC (DO-214AB) but larger than SMA (DO-214AC). This makes P6SMB7.5CAHM3_A/I ideal for designs needing higher energy handling than SMAJ-series parts without the PCB real estate penalty of SMCJ-series devices.
Does P6SMB7.5CAHM3_A/I require special PCB layout considerations?
Yes-optimal performance of P6SMB7.5CAHM3_A/I requires short, low-inductance traces between the device and protected line, with minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal as specified in the Vishay datasheet. Excessive trace length increases inductance, raising clamping voltage during fast transients; ground plane integrity and thermal relief design also impact sustained surge dissipation and thermal reliability.
