Product details
Overview
P6SMB510AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 485 V minimum breakdown voltage, 434 V standoff voltage, 698 V maximum clamping voltage at 0.86 A peak pulse current, 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 P6SMB510AHE3/5B datasheet, P6SMB510AHE3/5B pinout, P6SMB510AHE3/5B application, or P6SMB510AHE3/5B equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, standoff voltage compatibility with operating rail, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 485–535 V breakdown range at 1 mA test current. Its low incremental surge resistance ensures stable clamping under repetitive transients, while glass-passivated junction enhances reliability in harsh environments.
Designed for surface-mount automated placement, it meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, and supports operation from –65 °C to +150 °C junction temperature. The DO-214AA package provides mechanical robustness and thermal performance suitable for board-level ESD and lightning surge suppression without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 434 V - Maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected circuit's nominal DC rail. |
| Breakdown Voltage (VBR) | 485–535 V at 1 mA - Confirmed avalanche initiation range; defines threshold where clamping begins under surge conditions. |
| Clamping Voltage (VC) | 698 V at 0.86 A (10/1000 µs) - Peak voltage seen by downstream components during worst-case transient; critical for ensuring VDS(max) margin of protected MOSFETs. |
| Peak Pulse Power (PPPM) | 600 W - Sustained energy absorption capability under standardized 10/1000 µs surge; validates suitability for IEC 61000-4-5 Level 3/4 surges. |
| Junction Temperature Range | –65 °C to +150 °C - Enables deployment in automotive under-hood, industrial motor drives, and outdoor telecom equipment. |
| Thermal Resistance (RθJA) | 100 °C/W - Predicts junction-to-ambient temperature rise under steady-state dissipation; informs layout pad sizing for thermal management. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronic modules requiring reliability under temperature cycling, humidity, and mechanical shock per AEC stress test protocols. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, unidirectional polarity indicated by cathode band. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H), with 5.0 mm × 5.0 mm copper pads recommended per terminal for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or lowest potential point in protected circuit; completes conduction path during reverse-biased clamping event. |
| Cathode (banded end) | High-side surge input | Connected to line being protected (e.g., +400 V DC bus); reverse voltage applied here triggers avalanche breakdown into anode. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ510A | Same 510 V nominal breakdown, but 400 W PPPM; DO-214AC (SMA) package with higher RθJA (150 °C/W). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 due to reduced power handling. | Select when board space is constrained and surge threat level is limited to IEC Level 2 or lower. |
| 1.5KE510A | Through-hole DO-201 package; same 510 V VBR, 600 W rating, but no AEC-Q101 qualification or MSL Level 1 rating. | Not suitable for automated SMT lines or automotive applications requiring qualification traceability. | Choose only for legacy through-hole designs or non-automotive industrial prototypes where reflow compatibility is not required. |
Compared with SMAJ510A and 1.5KE510A, P6SMB510AHE3/5B delivers superior thermal performance in SMT layouts, full automotive qualification, and guaranteed 600 W clamping integrity - making it the preferred choice for high-reliability, high-volume surface-mount surge protection.

FAQ
What is the maximum clamping voltage of P6SMB510AHE3/5B under standard surge conditions?
The P6SMB510AHE3/5B has a maximum clamping voltage (VC) of 698 V when subjected to a 10/1000 µs waveform at 0.86 A peak pulse current. This value is measured per industry-standard test conditions and defines the highest voltage imposed on protected circuitry during a defined transient event. Engineers must verify that this clamping level remains safely below the absolute maximum ratings of downstream components such as MOSFETs or controllers in their specific design using the P6SMB510AHE3/5B.
Is P6SMB510AHE3/5B suitable for automotive applications?
Yes, P6SMB510AHE3/5B is AEC-Q101 qualified, meaning it has passed rigorous stress testing including temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - all required for automotive electronic modules. Its DO-214AA package, matte tin plating, and MSL Level 1 rating further support use in engine control units, battery management systems, and onboard chargers where reliability under thermal and mechanical stress is critical. The P6SMB510AHE3/5B meets these requirements without derating.
How does the standoff voltage (VWM) of P6SMB510AHE3/5B compare to its breakdown voltage?
The P6SMB510AHE3/5B has a standoff voltage (VWM) of 434 V and a minimum breakdown voltage (VBR) of 485 V at 1 mA test current - resulting in a 51 V margin between normal operating voltage and avalanche onset. This margin prevents false triggering during line tolerance variations or ripple, while still enabling fast response to overvoltage events. Designers must ensure system operating voltage stays below 434 V to avoid excessive leakage current, which could affect efficiency or accuracy in precision sensing circuits using the P6SMB510AHE3/5B.
What is the thermal resistance of P6SMB510AHE3/5B, and how does it impact layout?
The P6SMB510AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. This value directly determines temperature rise under steady-state power dissipation - for example, 0.5 W of continuous leakage would raise junction temperature by ~50 °C above ambient. Layout best practices require adhering to the recommended pad dimensions and avoiding thermal isolation; insufficient copper area will increase RθJA and risk exceeding the 150 °C max junction temperature of the P6SMB510AHE3/5B.
Does P6SMB510AHE3/5B have RoHS and halogen-free compliance?
Yes, P6SMB510AHE3/5B is RoHS-compliant per Directive 2011/65/EU and halogen-free per JEDEC JS709A standards. The "HE3" suffix explicitly denotes RoHS compliance and AEC-Q101 qualification, while matte tin plating satisfies J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements. These certifications are documented in Vishay's material category policy and apply to the P6SMB510AHE3/5B as shipped - no additional screening or declaration is needed for compliance-driven programs.
