Product details
Overview
P6SMB75A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power rails and signal lines. It features a 75 V standoff voltage (VWM), 71.3–78.8 V breakdown voltage (VBR) at 1 mA, 103 V maximum clamping voltage (VC) at 5.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive, industrial, and telecom power supply inputs.
For engineers reviewing the P6SMB75A-M3/52 datasheet, P6SMB75A-M3/52 pinout, P6SMB75A-M3/52 application, or P6SMB75A-M3/52 equivalent, this page delivers verified electrical parameters, SMB (DO-214AA) package details, clamping performance under surge conditions, thermal derating behavior, and AEC-Q101-qualified alternatives for automotive-grade design validation.
Technical Context
The P6SMB75A-M3/52 operates as a unidirectional avalanche diode with cathode-band polarity marking. Its glass-passivated junction enables fast response (<1 ns) to transient events and low incremental surge resistance, ensuring stable clamping during repetitive 10/1000 μs surges at 0.01% duty cycle.
Thermally, it exhibits RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), with rated operating junction temperature from –65 °C to +150 °C. The device is halogen-free, RoHS-compliant, and qualified to J-STD-020 MSL Level 1 (260 °C peak reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR @ IT = 1 mA | 71.3–78.8 V - Measured breakdown range confirming tight tolerance for predictable turn-on during transients. |
| VC @ IPPM = 5.8 A | 103 V - Clamped voltage during 600 W surge; determines protected circuit's maximum stress level. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 surge immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75A | Same SMB package, 75 V VWM, but lower PPPM = 400 W and higher VC = 121 V at 3.3 A. | Less robust clamping margin; suitable only for non-critical consumer-grade circuits with lower surge exposure. | Select SMAJ75A only if cost sensitivity outweighs surge immunity requirements and layout space allows tighter thermal margin. |
| P6SMB75AHM3_B | Identical electrical specs, but AEC-Q101 qualified and marked with "_B" revision code for automotive use. | Validated for automotive temperature cycling, HTRB, and mechanical shock; required for ASIL-B systems. | Choose P6SMB75AHM3_B when designing for automotive ECUs, ADAS sensors, or any application requiring certified reliability beyond commercial grade. |
Compared with SMAJ75A, P6SMB75A-M3/52 delivers 50% higher surge power handling and 18 V lower clamping voltage - critical for protecting modern low-voltage logic. Versus P6SMB75AHM3_B, it lacks AEC-Q101 validation but offers identical electrical performance at lower cost for industrial and telecom applications.

FAQ
What is the maximum clamping voltage of the P6SMB75A-M3/52 under surge conditions?
The P6SMB75A-M3/52 has a maximum clamping voltage (VC) of 103 V when subjected to its rated peak pulse current of 5.8 A using a 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 clamping performance remains stable across its operating temperature range, making P6SMB75A-M3/52 suitable for designs requiring predictable overvoltage limiting in harsh environments.
Is the P6SMB75A-M3/52 RoHS-compliant and halogen-free?
Yes, the P6SMB75A-M3/52 carries the "M3" suffix, indicating full RoHS compliance and halogen-free construction per IEC 61249-2-21. The molding compound meets UL 94 V-0 flammability rating, and terminals are matte tin plated per J-STD-002 and JESD 22-B102. This makes P6SMB75A-M3/52 appropriate for environmentally regulated markets including EU automotive and industrial equipment.
Does the P6SMB75A-M3/52 have AEC-Q101 qualification?
No, the P6SMB75A-M3/52 is a commercial-grade variant. However, the functionally identical P6SMB75AHM3_B is AEC-Q101 qualified and shares the same electrical characteristics and SMB package. If automotive qualification is required, P6SMB75AHM3_B should be selected instead of P6SMB75A-M3/52 - both parts use the same footprint and thermal profile, enabling drop-in replacement in validated designs.
What is the thermal resistance of the P6SMB75A-M3/52?
The P6SMB75A-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and a junction-to-lead resistance (RθJL) of 20 °C/W, measured on standard 0.2" × 0.2" copper pads. These values assume PCB layout per Vishay's recommended pad dimensions. Derating curves in the datasheet show power capability decreases linearly above 25 °C ambient, so thermal design must account for board copper area and airflow when deploying P6SMB75A-M3/52 in high-power or high-temperature environments.
How does the P6SMB75A-M3/52 compare to bidirectional TVS diodes like P6SMB75CA?
The P6SMB75A-M3/52 is unidirectional and intended for DC line protection where polarity is fixed (e.g., VIN to GND), offering lower leakage and sharper knee characteristics. In contrast, P6SMB75CA is bidirectional and suited for AC lines or differential signal pairs. Both share identical VBR, VC, and PPPM, but P6SMB75A-M3/52 uses cathode-band marking while P6SMB75CA has no polarity marking. Choose P6SMB75A-M3/52 for asymmetric DC rails and P6SMB75CA for symmetrical or AC-coupled paths.
