Product details
Overview
P6SMB75AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 75 V breakdown voltage (VBR = 71.3–78.8 V at 1 mA), 64.1 V stand-off voltage (VWM), 103 V maximum clamping voltage at 5.8 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and DC power rail protection.
For engineers reviewing the P6SMB75AHE3_B/I datasheet, P6SMB75AHE3_B/I pinout, P6SMB75AHE3_B/I application, or P6SMB75AHE3_B/I equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates as a clamping device that diverts transient energy to ground when reverse voltage exceeds VWM (64.1 V), entering avalanche breakdown at VBR (min 71.3 V). Its low incremental surge resistance and fast response time ensure effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The device is rated for repetitive 10/1000 μs pulses at 0.01 % duty cycle, with peak pulse current (IPPM) of 5.8 A and clamping voltage (VC) of 103 V. Junction temperature range spans –65 °C to +150 °C, and it meets J-STD-020 MSL Level 1 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA - defines precise avalanche onset threshold for reliable overvoltage triggering |
| VWM | 64.1 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 103 V at 5.8 A - clamped voltage seen by protected circuit during worst-case 600 W transient |
| PPPM | 600 W - peak pulse power handling per 10/1000 μs waveform, enabling protection against IEC 61000-4-5 Level 4 surges |
| IPPM | 5.8 A - peak surge current capability under standardized test condition |
| TJ max | +150 °C - maximum junction temperature supporting operation in under-hood automotive and industrial environments |
| RθJA | 100 °C/W - thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Anode (unbanded end) | Protected line input | Connected to line being safeguarded (e.g., 48 V supply rail or CAN bus line); reverse-biased during normal operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| 600 W peak pulse power | Withstands high-energy transients such as ISO 7637-2 Pulse 5a without degradation |
| Glass passivated junction | Ensures stable leakage performance and long-term reliability under thermal cycling |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow processes without preconditioning |
| Low profile SMB package | Enables compact PCB layouts and automated placement in space-constrained modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75A-E3/5B | Same VBR range (71.3–78.8 V), but lower PPPM = 400 W and higher VC = 121 V at 3.3 A | Not AEC-Q101 qualified; suitable for commercial-grade consumer or computing systems only | Select when cost sensitivity outweighs automotive qualification and surge margin requirements |
| 1.5SMC75A | Identical electrical specs but in larger SMC (DO-214AB) package; RθJA = 40 °C/W vs. 100 °C/W | Better thermal performance allows higher sustained surge repetition, but requires 30 % more board area | Choose when thermal management dominates layout constraints and PCB real estate is available |
Compared with SMAJ75A-E3/5B and 1.5SMC75A, P6SMB75AHE3_B/I delivers AEC-Q101 compliance in the smallest footprint (SMB), making it optimal for space-limited automotive modules where qualification and size are non-negotiable.

FAQ
What is the breakdown voltage tolerance of P6SMB75AHE3_B/I?
The P6SMB75AHE3_B/I has a specified breakdown voltage (VBR) range of 71.3 V to 78.8 V at 1 mA test current, representing ±5 % tolerance around the nominal 75 V rating. This tight distribution ensures predictable clamping onset across production lots and supports robust design margins in safety-critical circuits.
Is P6SMB75AHE3_B/I suitable for bidirectional transient protection?
No, P6SMB75AHE3_B/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the P6SMB75CA variant. Using P6SMB75AHE3_B/I in AC-coupled or symmetrical signal lines risks forward conduction during negative transients and invalidates its clamping specification.
Does P6SMB75AHE3_B/I require derating at elevated ambient temperatures?
Yes, P6SMB75AHE3_B/I must be derated above 25 °C ambient per Figure 2 in the datasheet. At 85 °C ambient, its peak pulse power drops to ~420 W (70 % of 600 W), and at 125 °C, it falls to ~240 W (40 %). Designers must apply this derating when sizing protection for under-hood or enclosed industrial enclosures.
What does the "HE3_B/I" suffix signify in P6SMB75AHE3_B/I?
The "HE3" denotes RoHS-compliant and AEC-Q101 qualified construction; "B" indicates AEC-Q101 qualification level for P6SMB6.8A–P6SMB220A devices; and "I" specifies 3200-unit quantity on 13-inch tape-and-reel packaging. This full suffix confirms automotive-grade reliability and logistics readiness for high-volume manufacturing.
Can P6SMB75AHE3_B/I replace P6SMB75AHE3_B/H on the same PCB?
Yes, P6SMB75AHE3_B/I is functionally and mechanically identical to P6SMB75AHE3_B/H - both share the same SMB (DO-214AA) package, electrical characteristics, and AEC-Q101 qualification. The only difference is packaging quantity: "I" = 3200 units/reel (13″), "H" = 750 units/reel (7″). No PCB or schematic changes are needed for substitution.
