Product details
Overview
P6SMB75AHE3/5B 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 a 75 V breakdown voltage (VBR = 71.3–78.8 V at IT = 1.0 mA), 64.1 V stand-off voltage (VWM), 103 V maximum clamping voltage (VC) at 5.8 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 industrial power supplies.
For engineers reviewing the P6SMB75AHE3/5B datasheet, P6SMB75AHE3/5B pinout, P6SMB75AHE3/5B application, or P6SMB75AHE3/5B equivalent, this device is selected for robust overvoltage protection where AEC-Q101 qualification, low incremental surge resistance, and fast response time (<1 ns) are required in automotive-grade power rail and interface line designs.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping shunt device triggered by reverse-biased avalanche breakdown. Its glass-passivated junction ensures stable leakage performance (≤1.0 μA at VWM) and repeatable clamping behavior across temperature (−65 °C to +150 °C).
The device delivers 600 W peak pulse power handling under standardized 10/1000 μs waveform conditions, with thermal resistance of RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation on standard 0.2" × 0.2" copper pads without active cooling in space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at 1.0 mA test current - defines precise avalanche onset window for predictable clamping threshold |
| VWM | 64.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 103 V at 5.8 A - clamped voltage during 600 W transient event, limiting downstream stress |
| IPPM | 5.8 A - peak pulse current capability under 10/1000 μs waveform, derated above 25 °C |
| PPPM | 600 W - peak pulse power rating per JEDEC-standard waveform, defining transient energy absorption capacity |
| TJ max. | +150 °C - maximum junction temperature enabling use in under-hood automotive and industrial ambient environments |
| Package | SMB (DO-214AA) - surface-mount outline with 0.220" × 0.130" footprint, compatible with automated placement and reflow |

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-E3/61 | Same SMB package, identical VBR (71.3–78.8 V), but rated for 400 W PPPM and not AEC-Q101 qualified | Limited to commercial-grade consumer/industrial use; lacks automotive reliability validation | Select when cost sensitivity outweighs automotive qualification requirements and 400 W pulse power suffices |
| 1.5SMC75A | Higher-power SMC package (same VBR, 1500 W PPPM), larger footprint (0.320" × 0.260"), RθJA = 30 °C/W | Requires more PCB area and supports higher-energy transients; less suitable for dense automotive modules | Choose for legacy designs needing higher surge margin or where thermal dissipation justifies larger package |
Compared with SMAJ75A-E3/61 and 1.5SMC75A, P6SMB75AHE3/5B uniquely balances AEC-Q101 qualification, 600 W pulse capability, and compact SMB footprint - making it optimal for new automotive and space-constrained industrial designs requiring validated reliability.

FAQ
What is the clamping voltage of P6SMB75AHE3/5B at its rated peak pulse current?
The P6SMB75AHE3/5B has a maximum clamping voltage (VC) of 103 V at its specified peak pulse current (IPPM) of 5.8 A under the 10/1000 μs waveform condition. This value is measured per JEDEC standards and reflects the actual voltage imposed on protected circuitry during a worst-case transient event. The clamping occurs rapidly (<1 ns), limiting stress on downstream components such as MOSFETs or microcontrollers in systems using the P6SMB75AHE3/5B.
Is P6SMB75AHE3/5B suitable for automotive applications?
Yes, P6SMB75AHE3/5B is AEC-Q101 qualified, as indicated by the "HE3" suffix, and is specifically intended for automotive use. It meets stringent reliability requirements including temperature cycling, humidity testing, and mechanical shock validation. The device operates across −65 °C to +150 °C junction temperature range and is rated for under-hood environments. Engineers selecting P6SMB75AHE3/5B for automotive power distribution modules or ADAS sensor interfaces can rely on its certified qualification status and tested performance.
What does the "5B" in P6SMB75AHE3/5B signify?
The "5B" in P6SMB75AHE3/5B denotes the packaging configuration: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This format supports high-volume automated SMT assembly and is distinct from the "52" variant (7-inch reel, 750 units). The "HE3" portion confirms RoHS-compliance and AEC-Q101 qualification, while "P6SMB75A" identifies the 75 V unidirectional TVS family member. All elements are manufacturer-defined ordering codes per Vishay's documentation.
How does P6SMB75AHE3/5B compare to bidirectional variants like P6SMB75CA?
P6SMB75AHE3/5B is unidirectional, with polarity marked by a cathode band and intended for DC line protection where current flows in one direction. In contrast, P6SMB75CA is bidirectional, offering symmetrical clamping for AC or floating signal lines. The unidirectional P6SMB75AHE3/5B provides lower leakage (<1.0 μA at 64.1 V) and tighter VBR tolerance versus bidirectional types, making it preferable for regulated DC rails. Selection depends on circuit topology - P6SMB75AHE3/5B is correct for VBAT-to-ground protection, while P6SMB75CA suits differential signal pairs.
What is the thermal resistance of P6SMB75AHE3/5B, and how does it affect layout?
P6SMB75AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on 0.2" × 0.2" copper pads per terminal. This means that under 5.8 A transient current, self-heating remains manageable without heatsinking - but sustained power dissipation must stay below 5.0 W (PD). Layout best practice requires adhering to Vishay's recommended pad dimensions (0.086" × 0.060") to ensure specified thermal performance and avoid derating penalties in the P6SMB75AHE3/5B design-in.
