Product details
Overview
P6KE8.2HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection on DC power rails and signal lines. It features a 6.45 V minimum breakdown voltage (VBR), 7.02 V maximum stand-off 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 body control modules to safeguard microcontrollers against load-dump transients.
For engineers reviewing the P6KE8.2HE3/54 datasheet, P6KE8.2HE3/54 pinout, P6KE8.2HE3/54 application, or P6KE8.2HE3/54 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified unidirectional TVS for board-level surge immunity where fast response (<1 ns), low clamping ratio (VC/VWM ≈ 1.72), and 175 °C junction temperature capability are critical selection criteria.
Technical Context
The P6KE8.2HE3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering precise voltage clamping during transient events such as ISO 7637-2 pulse 1 and pulse 2b. Its unidirectional polarity enables integration into DC-biased circuits without reverse conduction path concerns, and its DO-204AC (DO-15) package supports through-hole mounting with 20 °C/W junction-to-lead thermal resistance.
Clamping performance is defined at 49.6 A IPPM with 12.1 V VC under 10/1000 µs waveform, while leakage remains ≤200 µA at 7.02 V VWM. The device exhibits +0.065 %/°C temperature coefficient of VBR, ensuring stable breakdown across automotive ambient ranges (–55 °C to +125 °C operating ambient).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 6.45 V - guaranteed avalanche initiation threshold at 10 mA test current, defining earliest clamping onset |
| VWM | 7.02 V - maximum continuous reverse working voltage before significant leakage (≤200 µA) |
| VC @ IPPM | 12.1 V - clamped voltage seen by protected circuit during 49.6 A 10/1000 µs surge |
| PPPM | 600 W - peak transient power absorption capacity, enabling single-event suppression of 100 V × 6 A surges |
| IPPM | 49.6 A - maximum non-repetitive surge current supported under standard waveform, derated above 25 °C |
| TJ max | 175 °C - maximum junction temperature, supporting operation in engine bay or power supply environments |

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; 600 W rating; same AEC-Q101 qualification | Surface-mount alternative requiring PCB redesign; lower profile but higher thermal resistance (RθJA = 110 °C/W vs. 75 °C/W) | Select when space-constrained layouts demand SMD placement and reflow compatibility is required. |
| 1.5KE8.2A | Same DO-204AC package; identical VBR/VWM/VC specs; 1500 W PPPM; no AEC-Q101 qualification; commercial grade only | Higher power handling for rare high-energy transients; unsuitable for automotive due to missing qualification | Select for cost-sensitive industrial power supplies where AEC-Q101 is not mandated and surge energy exceeds 600 W. |
Compared with SMBJ8.0A and 1.5KE8.2A, the P6KE8.2HE3/54 uniquely combines AEC-Q101 qualification, through-hole DO-15 compatibility, and optimized clamping for 5–12 V systems - making it the preferred choice for automotive and industrial designs requiring traceable, qualified surge protection without SMT conversion.

FAQ
What is the breakdown voltage tolerance of P6KE8.2HE3/54?
The P6KE8.2HE3/54 has a specified breakdown voltage range of 7.79 V (min) to 8.61 V (max) at 10 mA test current, corresponding to a ±5.3% tolerance around the nominal 8.2 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports reliable design margining in 5 V and 12 V systems where the P6KE8.2HE3/54 is commonly applied.
Is P6KE8.2HE3/54 suitable for bidirectional transient suppression?
No, P6KE8.2HE3/54 is a unidirectional TVS diode - its cathode band indicates polarity, and it conducts only during positive transients relative to the anode. For bidirectional protection, Vishay offers the P6KE8.2CA variant (with CA suffix); using P6KE8.2HE3/54 in AC or floating applications risks failure due to reverse conduction beyond VWM. Always verify polarity alignment in schematic capture for P6KE8.2HE3/54.
What does the "HE3/54" suffix mean in P6KE8.2HE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred packaging code - 4000-piece 13-inch paper tape and reel. This distinguishes P6KE8.2HE3/54 from commercial-grade P6KE8.2A-E3/54 (E3 = RoHS, no AEC-Q101) and confirms full automotive suitability for P6KE8.2HE3/54.
How does P6KE8.2HE3/54 perform under elevated ambient temperatures?
P6KE8.2HE3/54 derates linearly above 25 °C ambient: peak pulse power drops to ~450 W at 85 °C and ~300 W at 125 °C per Vishay's Fig. 2 curve. Its 175 °C maximum junction temperature allows operation in under-hood environments when PCB copper area and lead length are optimized per thermal guidelines - confirming P6KE8.2HE3/54's suitability for engine control unit designs.
Can P6KE8.2HE3/54 replace P6KE6.8A in a 3.3 V circuit?
No - P6KE6.8A has VWM = 5.8 V and VC = 10.5 V, making it appropriate for 3.3 V rails; P6KE8.2HE3/54's 7.02 V VWM exceeds typical 3.3 V system tolerances and risks excessive leakage or premature clamping. Using P6KE8.2HE3/54 in place of P6KE6.8A would compromise signal integrity and power efficiency - always match VWM to the protected rail's maximum steady-state voltage for P6KE8.2HE3/54 deployment.
