Product details
Overview
P6KE8.2AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 7.79 V minimum breakdown voltage (VBR), 8.61 V maximum VBR, 7.02 V standoff voltage (VWM), 12.1 V clamping voltage (VC) at 49.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE8.2AHE3/54 datasheet, P6KE8.2AHE3/54 pinout, P6KE8.2AHE3/54 application, or P6KE8.2AHE3/54 equivalent, key selection criteria include verified unidirectional polarity, DO-15 package thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification, and clamping performance under repetitive 0.01% duty cycle surges.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (7.02 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins against ESD and inductive switching spikes.
Thermal design relies on lead-to-ambient dissipation (RθJA = 75 °C/W) and junction-to-lead resistance (20 °C/W); derating begins above 25 °C ambient per Fig. 2, with maximum junction temperature rated at +175 °C. The matte tin-plated DO-15 leads comply with J-STD-002 solderability and JESD 201 Class 2 whisker resistance (HE3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.02 V - Maximum continuous reverse operating voltage before avalanche onset; sets upper limit for safe DC bias in protected line. |
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - Confirmed breakdown range defining turn-on threshold consistency across production lots. |
| VC @ IPPM | 12.1 V at 49.6 A - Clamped voltage during 600 W transient; determines worst-case overvoltage seen by protected IC. |
| IPPM | 49.6 A - Peak surge current capability with 10/1000 µs waveform; defines single-pulse energy handling (≈3.3 J). |
| PPPM | 600 W - Peak pulse power rating; validates suitability for automotive load-dump and industrial relay-coil suppression. |
| TJ max. | +175 °C - Maximum junction temperature; enables operation in under-hood or high-temperature industrial enclosures. |
| Leakage ID | 200 µA at VWM - Low reverse leakage preserves battery life in always-on automotive modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package; 8.0 V VWM, 12.0 V VC @ 49.2 A; same 600 W rating but lower RθJA (50 °C/W). | Better thermal performance in surface-mount layouts; not through-hole compatible. | Select SMBJ8.0A for SMT designs requiring higher power density and automated assembly. |
| 1.5KE8.2A | Same DO-15 package; identical VWM/VBR/VC specs but commercial-grade only (no AEC-Q101 qualification). | Lacks automotive qualification; suitable for cost-sensitive industrial or consumer use only. | Choose 1.5KE8.2A where AEC-Q101 is not mandated and BOM cost reduction is prioritized. |
Compared with SMBJ8.0A and 1.5KE8.2A, P6KE8.2AHE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole reliability, and validated 200 µA leakage at VWM - making it optimal for automotive and harsh-environment replacements where mechanical robustness and qualification traceability are mandatory.

FAQ
What is the clamping voltage of P6KE8.2AHE3/54 and how is it measured?
The clamping voltage (VC) of P6KE8.2AHE3/54 is 12.1 V, measured at 49.6 A peak pulse current using a 10/1000 µs waveform per Fig. 1 in the Vishay datasheet. This value represents the maximum voltage imposed on the protected circuit during a standardized surge event and is guaranteed across the full operating temperature range. P6KE8.2AHE3/54 maintains this clamping performance due to its low incremental surge resistance and glass-passivated junction structure.
Is P6KE8.2AHE3/54 suitable for automotive applications?
Yes, P6KE8.2AHE3/54 is AEC-Q101 qualified (HE3 suffix), confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its construction - matte tin-plated DO-15 leads, JESD 201 Class 2 whisker resistance, and operation up to +175 °C junction temperature - meets automotive reliability requirements. P6KE8.2AHE3/54 has been validated for ISO 7637-2 pulse testing and load-dump immunity in production vehicle systems.
What does the 'HE3/54' suffix mean in P6KE8.2AHE3/54?
The 'HE3' suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; '54' denotes the preferred package code for 13-inch paper tape and reel packaging (4000 units per reel). This ordering code ensures traceable sourcing, automotive-grade screening, and compatibility with standard through-hole assembly processes. P6KE8.2AHE3/54 is distinct from commercial-grade variants like P6KE8.2AE3/54, which lack AEC-Q101 validation.
How does P6KE8.2AHE3/54 compare to bidirectional TVS diodes?
P6KE8.2AHE3/54 is unidirectional and intended for DC circuits with defined polarity, such as 5 V or 12 V power rails, where the cathode connects to the protected line and anode to ground. Bidirectional variants (e.g., P6KE8.2CA) are used in AC or floating signal paths like RS-485 or antenna lines. P6KE8.2AHE3/54 offers tighter VBR tolerance and lower leakage than equivalent bidirectional types, making it preferable for precision DC protection where reverse conduction must be avoided.
What is the maximum leakage current of P6KE8.2AHE3/54 at its standoff voltage?
The maximum reverse leakage current (ID) of P6KE8.2AHE3/54 is 200 µA at its 7.02 V standoff voltage (VWM), measured at 25 °C ambient. This low leakage preserves battery life in always-on automotive modules and avoids loading errors in high-impedance sensor signal paths. P6KE8.2AHE3/54 maintains leakage below 500 µA up to +125 °C, supporting reliable operation in under-hood environments.
