Product details
Overview
P6SMB7.5AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 7.13 V minimum breakdown voltage (VBR), 6.40 V standoff voltage (VWM), 11.3 V maximum clamping voltage at 53.1 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB7.5AHE3_B/I datasheet, P6SMB7.5AHE3_B/I pinout, P6SMB7.5AHE3_B/I application, or P6SMB7.5AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HE3 suffix), RoHS-compliant matte tin terminals, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its 7.13–7.88 V breakdown range (IT = 10 mA), limiting transient energy to safe levels for downstream components. Its low incremental surge resistance and fast response time ensure effective suppression of ESD, inductive switching spikes, and lightning-induced surges.
The device is rated for 150 °C maximum junction temperature, 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), and exhibits 0.061 %/°C temperature coefficient of VBR. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), confirming suitability for moderate-power board-level protection without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA test current - defines precise avalanche onset threshold for reliable overvoltage triggering |
| VWM | 6.40 V - maximum continuous reverse operating voltage before leakage exceeds 500 μA |
| VC @ IPPM | 11.3 V at 53.1 A peak pulse current - clamped voltage seen by protected circuit during worst-case 10/1000 μs transient |
| PPPM | 600 W - peak pulse power handling capability under standardized 10/1000 μs waveform, 0.01% duty cycle |
| IFSM | 100 A - single half-sine surge current rating (8.3 ms), critical for inductive load switch-off protection |
| TJ max. | 150 °C - enables operation in under-hood automotive and high-temperature industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Same VWM (6.4 V), but lower PPPM (400 W) and higher VC (12.0 V at 33.3 A); SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; not AEC-Q101 qualified; unsuitable for automotive under-hood use | Select when cost or board area is prioritized over automotive qualification and 600 W surge margin |
| 1.5SMC7.5A | Same electrical specs (VWM, VBR, VC, PPPM), but larger SMC (DO-214AB) package; higher thermal mass but 20% larger PCB area | Better thermal dissipation in high-ambient environments; compatible with legacy SMC footprints but incompatible with SMB layout | Choose when existing PCB design uses SMC pads or when extended thermal cycling reliability is required beyond SMB limits |
Compared with SMAJ7.5A and 1.5SMC7.5A, P6SMB7.5AHE3_B/I uniquely combines AEC-Q101 qualification, SMB footprint efficiency, and full 600 W surge rating - making it the optimal choice for new automotive and space-constrained industrial designs requiring validated reliability.

FAQ
What is the exact breakdown voltage range for P6SMB7.5AHE3_B/I?
The P6SMB7.5AHE3_B/I has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage protection design for 5 V and 6 V systems. The P6SMB7.5AHE3_B/I datasheet specifies this range under TA = 25 °C conditions with no derating applied.
Is P6SMB7.5AHE3_B/I suitable for automotive applications?
Yes, P6SMB7.5AHE3_B/I is AEC-Q101 qualified (indicated by HE3 suffix and _B revision code), tested for temperature cycling, humidity bias, and mechanical shock per automotive standards. It operates from -65 °C to +150 °C junction temperature and meets MSL Level 1 for lead-free reflow - making P6SMB7.5AHE3_B/I appropriate for engine control units, body electronics, and ADAS modules where reliability under vibration and thermal stress is critical.
What does the "_B/I" suffix mean in P6SMB7.5AHE3_B/I?
The "_B" denotes AEC-Q101 qualification for the P6SMB7.5AHE3_B/I series (applicable to P6SMB6.8A through P6SMB220A), while "/I" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. The "HE3" portion confirms RoHS-compliant, matte tin-plated leads and commercial-grade construction with automotive qualification overlay - all verified in Vishay document 88370, revision 09-Jan-2024.
How does P6SMB7.5AHE3_B/I compare to bidirectional variants like P6SMB7.5CA?
P6SMB7.5AHE3_B/I is unidirectional, with cathode marked by a band and intended for DC line protection (e.g., 5 V rail to ground). In contrast, P6SMB7.5CA is bidirectional, lacks polarity marking, and protects AC or dual-polarity signals. Their VWM (6.4 V), VBR (7.13–7.88 V), and VC (11.3 V) match, but P6SMB7.5AHE3_B/I cannot replace P6SMB7.5CA in AC-coupled circuits without redesigning the grounding scheme.
What is the maximum clamping voltage of P6SMB7.5AHE3_B/I under surge conditions?
The P6SMB7.5AHE3_B/I clamps to a maximum of 11.3 V when subjected to its rated 53.1 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at TA = 25 °C on 0.2" × 0.2" copper pads and remains stable across its -65 °C to +150 °C operating junction temperature range - ensuring predictable protection margins for 5 V logic and analog circuits.
