Product details
Overview
P6SMB7.5A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 7.13 V minimum breakdown voltage (VBR), 6.40 V standoff voltage (VWM), and 11.3 V maximum clamping voltage (VC) at 53.1 A peak pulse current. It delivers 600 W peak pulse power (10/1000 μs waveform) for protecting MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and automotive electronics.
For engineers reviewing the P6SMB7.5A-M3/52 datasheet, P6SMB7.5A-M3/52 pinout, P6SMB7.5A-M3/52 application, or P6SMB7.5A-M3/52 equivalent, this halogen-free, RoHS-compliant TVS offers verified clamping performance, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification eligibility via HM3 suffix variants - critical for board-level surge protection design validation.
Technical Context
This unidirectional TVS operates by avalanche breakdown to clamp transient overvoltages above its 6.40 V standoff threshold, limiting downstream voltage to ≤11.3 V during 53.1 A pulses. Its glass-passivated junction ensures stable leakage (<500 μA at VWM) and fast response time (<1 ns), enabling protection of low-voltage logic interfaces and analog sensor inputs.
The device is rated for 150 °C maximum junction temperature and exhibits 0.061 %/°C temperature coefficient of VBR, supporting reliable operation across extended thermal ranges. Its 100 °C/W junction-to-ambient thermal resistance requires PCB copper pad heatsinking per recommended 0.2" × 0.2" layout for sustained 5.0 W power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 6.40 V - Maximum continuous reverse voltage before conduction begins; sets operating margin below clamping threshold. |
| VBR (Breakdown, min) | 7.13 V - Minimum voltage at which avalanche conduction initiates at 10 mA test current; defines turn-on consistency. |
| VC (Clamping, max) | 11.3 V - Maximum voltage seen across device at 53.1 A peak pulse; determines protected circuit's worst-case overvoltage exposure. |
| IPPM | 53.1 A - Peak pulse current capability under 10/1000 μs waveform; quantifies surge energy handling capacity. |
| PPPM | 600 W - Peak pulse power rating; enables robust protection against lightning-induced or inductive-switching transients. |
| ID (Leakage) | ≤500 μA at VWM - Reverse leakage current level; ensures minimal standby power loss and signal integrity in high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive or enclosed industrial environments. |

|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive kickback in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Unidirectional clamping element placed between signal line and chassis ground, responding within <1 ns to limit transients to ≤11.3 V. Use Value: Prevents latch-up or permanent damage to 5 V-tolerant transceivers and ADC front-ends while maintaining signal fidelity during normal operation. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise in factory automation cabinets. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected across optocoupler input terminals or microcontroller GPIO pins to shunt EFT bursts and surge currents. Use Value: Eliminates need for external RC snubbers or varistors, reducing BOM count and PCB area while meeting IEC 61000-4-4 (EFT) and -4-5 (surge) immunity requirements. |
| Consumer Power Adapter Input | Telecom Line Interface Protection |
|
Use Scenario: Secondary-side DC output protection in wall adapters and USB PD chargers against output short-circuit recovery spikes and capacitor discharge transients. IC Role / Device Role / Timing Role: Unidirectional TVS mounted directly at DC output connector, clamping overvoltage before it reaches downstream USB-C controller or battery management IC. Use Value: Limits post-regulator overvoltage to safe levels (<12 V) during fault conditions, preventing catastrophic failure of Type-C port controllers and associated firmware. |
Use Scenario: Overvoltage suppression on Ethernet PHY differential pairs and auxiliary power lines in PoE-powered access points and IP cameras. IC Role / Device Role / Timing Role: Discrete TVS pair (one per line) referenced to local ground plane, clamping common-mode surges induced by nearby AC wiring or lightning coupling. Use Value: Maintains signal integrity up to 100 MHz while surviving repeated 10/700 μs telecom surges per ITU-T K.21, extending field reliability without active protection circuitry. |
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 SMB package, identical VWM/VBR/VC specs, but rated for 400 W PPPM (vs. 600 W); higher leakage (1000 μA). | Limited to lower-energy transients (e.g., IEC 61000-4-4 Level 2); not suitable for 12 V automotive load dump where 600 W margin is required. | Select P6SMB7.5A-M3/52 when full 600 W surge headroom and <500 μA leakage are mandatory for mission-critical sensing nodes. |
| 1.5SMC7.5A | Higher-power SMC package (same VWM/VBR), 1500 W PPPM, larger footprint (7.11 mm × 6.22 mm vs. 4.57 mm × 3.94 mm), 10× higher thermal mass. | Requires PCB redesign; suited for primary-side AC/DC input protection rather than space-constrained secondary-side IC protection. | Choose P6SMB7.5A-M3/52 for compact, high-density layouts where SMB footprint and 600 W capability meet system-level surge test requirements. |
Compared with SMAJ7.5A and 1.5SMC7.5A, P6SMB7.5A-M3/52 uniquely balances 600 W surge capacity, SMB footprint, <500 μA leakage, and halogen-free compliance - making it optimal for automotive-grade sensor modules and industrial I/O where size, reliability, and regulatory alignment are jointly constrained.

FAQ
What is the clamping voltage of P6SMB7.5A-M3/52 at its rated peak pulse current?
The P6SMB7.5A-M3/52 has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and represents the highest voltage that will appear across the device during a full-rated surge event, ensuring downstream 5 V or 3.3 V ICs remain within safe operating limits. The P6SMB7.5A-M3/52 achieves this with low incremental resistance, minimizing overshoot beyond the specified VC.
Is P6SMB7.5A-M3/52 suitable for automotive applications?
Yes, P6SMB7.5A-M3/52 is halogen-free and RoHS-compliant, and its base P6SMB7.5A family is AEC-Q101 qualified when ordered with HE3 or HM3 suffixes (e.g., P6SMB7.5AHM3_B). While the M3/52 variant itself is commercial-grade, it shares identical electrical and thermal characteristics with qualified versions and is widely deployed in non-safety-critical automotive subsystems such as body control modules and sensor interfaces. For full qualification, specify HM3-B or HM3-I suffixes.
How does the M3 suffix differ from E3 in P6SMB7.5A-M3/52?
The M3 suffix in P6SMB7.5A-M3/52 denotes halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, whereas E3 indicates standard RoHS compliance without halogen-free assurance. Both meet J-STD-020 MSL Level 1 and have identical electrical specifications. The M3 version is preferred for strict environmental compliance programs, especially in European and Japanese automotive supply chains where halogen content restrictions apply.
What is the thermal resistance of P6SMB7.5A-M3/52, and how does it affect layout?
P6SMB7.5A-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This means a 5.0 W steady-state power dissipation would raise junction temperature by 500 °C above ambient - far exceeding its 150 °C limit. Therefore, the device is intended for transient-only duty (0.01% duty cycle); layout must follow Vishay's pad dimensions to ensure reliable 600 W pulse handling without thermal runaway during surge events.
Can P6SMB7.5A-M3/52 be used in bidirectional configurations?
No, P6SMB7.5A-M3/52 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires the CA suffix (e.g., P6SMB7.5CA), which internally connects two opposing diodes. Using P6SMB7.5A-M3/52 in reverse-biased AC signal paths would result in forward conduction and failure. For bidirectional protection at 7.5 V standoff, select P6SMB7.5CA-M3/52 - it provides symmetrical clamping in both directions with same VWM, VBR, and VC ratings.
