Product details
Overview
P6KE510A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for robust overvoltage protection of sensitive electronics. It features a 485 V minimum breakdown voltage (VBR), 434 V maximum standoff voltage (VWM), 698 V clamping voltage (VC) at 0.86 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the P6KE510A-E3/54 datasheet, P6KE510A-E3/54 pinout, P6KE510A-E3/54 application, or P6KE510A-E3/54 equivalent, key selection criteria include its unidirectional polarity, DO-15 mechanical compatibility, 175 °C max junction temperature, AEC-Q101 qualification status, and clamping performance under high-energy transients per IEC 61000-4-5.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (434 V), it avalanches rapidly to clamp at ≤698 V, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM).
Rated for 600 W peak pulse power (10/1000 µs), it sustains repetitive surges at 0.01 % duty cycle and handles 100 A non-repetitive forward surge (8.3 ms half-sine). Thermal resistance is 20 °C/W junction-to-lead, enabling reliable operation up to 175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 434 V maximum - defines highest continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 485 V / 535 V at 1.0 mA - ensures predictable avalanche onset across production lot and temperature |
| VC @ IPPM | 698 V at 0.86 A - maximum clamped voltage during 10/1000 µs surge, limiting stress on protected ICs |
| PPPM | 600 W - peak transient energy absorption capability without failure under standardized waveform |
| IFSM | 100 A - non-repetitive forward surge rating, critical for inductive load switching events |
| TJ max | 175 °C - enables use in under-hood automotive and high-ambient industrial environments |
| RθJL | 20 °C/W - low thermal resistance supports power dissipation in lead-mounted configurations |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to ground or low-impedance reference in unidirectional configuration |
| Cathode | Avalanche conduction terminal | Connected to protected line; conducts when voltage exceeds VWM, clamping to VC |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance (±5 %), low leakage (<1 µA), and long-term reliability under thermal cycling |
| 600 W peak pulse power (10/1000 µs) | Provides immunity against severe transients per ISO 7637-2 Pulse 5a and IEC 61000-4-5 Level 4 |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive powertrain and chassis applications requiring zero defect and extended temperature operation |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for 48 V systems |
| Solder dip 275 °C max., 10 s | Enables compatibility with standard wave soldering processes without parametric shift or delamination |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ510A | DO-214AA package, 510 V VWM, same 600 W rating but lower VC (670 V), higher capacitance (150 pF) | Better suited for PCB space-constrained designs; less optimal for high-frequency signal lines due to higher CJ | Select SMBJ510A when footprint reduction and slightly tighter clamping are prioritized over leaded mounting and legacy DO-15 compatibility. |
| 1.5KE510A | Same DO-15 package, 510 V VWM, but 1500 W rating (10/1000 µs), higher IPPM (2.1 A), larger thermal mass | Required where system-level surge testing exceeds 600 W (e.g., MIL-STD-1275E Class V) | Choose 1.5KE510A when higher single-pulse energy handling is mandated, accepting larger physical size and higher cost. |
Compared with SMBJ510A and 1.5KE510A, P6KE510A-E3/54 delivers optimal balance of DO-15 legacy compatibility, AEC-Q101 qualification, and 600 W surge capacity - making it ideal for cost-sensitive, volume automotive and industrial control applications where proven reliability and standardized assembly are critical.

FAQ
What is the maximum clamping voltage of P6KE510A-E3/54 under standard test conditions?
The maximum clamping voltage (VC) of P6KE510A-E3/54 is 698 V when subjected to a 10/1000 µs waveform at 0.86 A peak pulse current (IPPM). This value is measured per JEDEC standards and reflects worst-case voltage seen by protected circuitry during surge events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings. The P6KE510A-E3/54 maintains this clamping performance across its full operating temperature range.
Is P6KE510A-E3/54 qualified for automotive applications?
Yes, P6KE510A-E3/54 is AEC-Q101 qualified, as confirmed by Vishay's documentation for the E3 suffix variant. This qualification validates its reliability for automotive powertrain, chassis, and body electronics applications, including operation from -55 °C to +175 °C junction temperature and resistance to mechanical shock, vibration, and thermal cycling. The P6KE510A-E3/54 meets requirements for under-hood and battery-line protection where zero-defect performance is mandatory.
What is the standoff voltage rating of P6KE510A-E3/54, and how does it relate to system design?
The maximum standoff voltage (VWM) of P6KE510A-E3/54 is 434 V, meaning it remains in high-impedance state below this DC or RMS voltage level. In system design, VWM must exceed the maximum normal operating voltage - for example, ≥120 % of a 360 V DC bus - to prevent leakage or premature conduction. The P6KE510A-E3/54's 434 V VWM makes it suitable for 48 V and 380–400 V nominal systems with appropriate derating margins.
How does the DO-15 package of P6KE510A-E3/54 impact thermal performance?
The DO-15 (DO-204AC) package of P6KE510A-E3/54 provides a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling effective heat transfer to PCB copper or heatsinks via axial leads. Unlike surface-mount packages, DO-15 allows direct lead soldering to thermal pads or chassis ground, supporting sustained 5.0 W power dissipation at TL = 75 °C. This thermal behavior is integral to the P6KE510A-E3/54's ability to survive repetitive surge events without thermal runaway.
Can P6KE510A-E3/54 be used in bidirectional configurations?
No - P6KE510A-E3/54 is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). Its cathode band denotes polarity, and it conducts only in reverse breakdown. For bidirectional protection, Vishay specifies variants like P6KE440CA. Using P6KE510A-E3/54 in AC-coupled or symmetrical signal paths would result in forward conduction during negative half-cycles, potentially damaging the device or circuit. Always verify polarity marking and select CA-suffix parts for true bidirectional applications.
