Product details
Overview
P6SMB510A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 510 V breakdown voltage (VBR = 485–535 V at IT = 1.0 mA), 600 W peak pulse power (10/1000 μs), and clamps transients to ≤698 V at 0.86 A, making it suitable for protecting industrial power supplies and telecom interface circuits against lightning-induced surges.
For engineers reviewing the P6SMB510A-E3/52 datasheet, P6SMB510A-E3/52 pinout, P6SMB510A-E3/52 application, or P6SMB510A-E3/52 equivalent, key selection criteria include standoff voltage (VWM = 434 V), clamping performance under 10/1000 μs waveform, thermal resistance (RθJA = 100 °C/W), RoHS-compliant SMB (DO-214AA) packaging, and AEC-Q101 qualification eligibility via HE3/HM3 variants.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable avalanche behavior. Its 600 W peak pulse rating is specified per 10/1000 μs waveform at 0.01% duty cycle, with derating above TA = 25 °C per Fig. 2 of the datasheet.
The device exhibits low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of fast-rising transients induced by inductive switching or ESD events. Junction temperature is rated from –65 °C to +150 °C, and thermal resistance from junction-to-ambient is 100 °C/W on standard 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 485 V / 535 V at IT = 1.0 mA - defines reliable avalanche initiation range under standardized test current |
| VWM | 434 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | ≤698 V at 0.86 A - clamping voltage during full 600 W transient, critical for downstream IC survivability |
| PPPM | 600 W (10/1000 μs) - peak surge energy handling capacity under standard lightning surge waveform |
| ID @ VWM | ≤1.0 μA - ultra-low reverse leakage ensures minimal standby power loss in high-impedance circuits |
| RθJA | 100 °C/W - thermal resistance determines junction temperature rise under sustained power dissipation |
| TJ max | +150 °C - maximum allowable junction temperature for long-term reliability in harsh environments |

IC Role / Device Role / Timing Role: Unidirectional TVS clamp that diverts >600 W transient energy away from upstream rectifier diodes and downstream DC-DC controllers. Use Value: Limits voltage excursion to ≤698 V during 10/1000 μs surges, preventing catastrophic failure of 100 V-rated MOSFETs and gate drivers in front-end stages. | Use Scenario: Placed at the DC input of remote radio units (RRUs) powered via long overhead or underground cables exposed to indirect lightning. IC Role / Device Role / Timing Role: Primary overvoltage protection element absorbing surge energy before it reaches sensitive RF power amplifiers and bias control ICs. Use Value: Maintains system uptime by surviving repeated 6 kV/3 kA surges per IEC 61000-4-5, thanks to stable clamping and low thermal resistance (RθJA = 100 °C/W). |
| Renewable Energy Inverter DC Link | High-Voltage Sensor Interface Protection |
Use Scenario: Mounted across DC link capacitors in solar string inverters where PV array transients couple into the 600–1000 V bus. IC Role / Device Role / Timing Role: Secondary surge limiter backing up MOV-based primary protection, providing precise clamping at 510 V standoff. Use Value: Prevents false triggering of overvoltage protection circuits by limiting transient overshoot to <700 V, ensuring uninterrupted grid synchronization. | Use Scenario: Protecting isolated analog front-ends of voltage sensors measuring HV DC bus in EV chargers or battery management systems. IC Role / Device Role / Timing Role: Input-stage TVS safeguarding precision op-amps and ADC references from coupling noise and ESD on sensor signal paths. Use Value: Delivers sub-1 μA leakage at 434 V, preserving measurement accuracy while clamping fast transients before they propagate through isolation barriers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ510A | Same 510 V VBR, but 600 W rating tested at 10/1000 μs with identical clamping (VC = 698 V), same SMB package and RoHS E3 suffix | No functional difference; direct second-source option with identical electrical and mechanical specs | Select when dual-sourcing is required without layout or validation changes |
| 1.5SMC510A | Higher package thermal resistance (RθJA ≈ 125 °C/W), larger SMC (DO-214AB) footprint, same VBR/VC but lower mounting density | Requires PCB redesign due to 2.54 mm longer body and different pad layout; suited for manual assembly or high-reliability aerospace use | Choose only if legacy SMC footprint compatibility or higher single-pulse IFSM (200 A) is mandatory |
Compared with SMBJ510A, P6SMB510A-E3/52 offers identical surge performance and drop-in compatibility; versus 1.5SMC510A, it delivers superior board space efficiency and thermal performance in automated SMT lines, though with lower single-pulse surge margin.

FAQ
What is the standoff voltage (VWM) of the P6SMB510A-E3/52?
The P6SMB510A-E3/52 has a maximum reverse standoff voltage (VWM) of 434 V, meaning it remains non-conductive with leakage <1.0 μA up to this DC or RMS voltage. This value ensures compatibility with 400–450 V DC bus systems while maintaining sufficient margin below the 485 V minimum breakdown voltage. The P6SMB510A-E3/52 must not be operated continuously above 434 V to avoid accelerated degradation.
Does the P6SMB510A-E3/52 meet automotive qualification standards?
The base P6SMB510A-E3/52 is a commercial-grade RoHS-compliant part and is not AEC-Q101 qualified. However, Vishay offers automotive-grade variants under ordering codes P6SMB510AHE3_D or P6SMB510AHM3_D (with "_D" suffix), which are fully AEC-Q101 qualified for use in automotive powertrain and chassis applications. The P6SMB510A-E3/52 itself is intended for industrial and telecom use only.
What is the clamping voltage (VC) of the P6SMB510A-E3/52 under surge conditions?
The P6SMB510A-E3/52 clamps to a maximum of 698 V when subjected to its rated 600 W peak pulse current (IPPM = 0.86 A) using the standard 10/1000 μs waveform. This clamping voltage is measured at the device terminals under defined test conditions and represents the upper limit seen by downstream components during surge events. The P6SMB510A-E3/52 achieves this with low incremental resistance, minimizing voltage overshoot beyond the specified VC.
Can the P6SMB510A-E3/52 be used in bidirectional configurations?
No - the P6SMB510A-E3/52 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires a CA-suffixed part such as P6SMB510CA. Using the P6SMB510A-E3/52 in reverse-biased AC applications would result in forward conduction and potential failure. For symmetric surge protection (e.g., data lines), the P6SMB510A-E3/52 is unsuitable without external circuitry.
What is the thermal resistance (RθJA) of the P6SMB510A-E3/52, and how does it affect layout?
The P6SMB510A-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal copper area; reducing pad size increases RθJA, risking junction overheating during repetitive surges. To maintain reliability, PCB layout must adhere to Vishay's recommended pad dimensions and avoid excessive trace length or narrow traces between the P6SMB510A-E3/52 and ground/power planes.
