Product details
Overview
P6KE8.2A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for circuit-level overvoltage protection. It features 600 W peak pulse power (10/1000 μs), 7.79–8.61 V breakdown voltage at 10 mA, 7.02 V stand-off voltage, 12.1 V maximum clamping voltage at 49.6 A peak pulse current, and ±0.065 %/°C temperature coefficient - deployed to safeguard MOSFETs, ICs, and sensor signal lines against inductive switching transients.
For engineers reviewing the P6KE8.2A-E3/54 datasheet, P6KE8.2A-E3/54 pinout, P6KE8.2A-E3/54 application, or P6KE8.2A-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected device VDS/VCC, standoff voltage compatibility with operating rail, thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and DO-15 mechanical fit in space-constrained PCB layouts.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, triggering conduction when reverse voltage exceeds its specified VBR range (7.79–8.61 V). Its low incremental surge resistance and sub-nanosecond response time enable effective suppression of fast-rising transients from inductive loads or ESD events.
Clamping performance is defined at IPPM = 49.6 A (10/1000 μs waveform), delivering VC ≤ 12.1 V - ensuring protected devices remain below absolute maximum ratings. Thermal design relies on RθJL = 20 °C/W and TJ(max) = 175 °C, with derating required above 25 °C ambient per Figure 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - defines precise avalanche onset window for reliable, repeatable clamping initiation |
| VWM | 7.02 V - maximum continuous reverse operating voltage before leakage exceeds 200 μA |
| VC @ IPPM | 12.1 V at 49.6 A - clamped voltage during worst-case 600 W transient, critical for downstream device voltage margin |
| PPPM | 600 W (10/1000 μs) - peak surge energy handling capacity under standardized lightning/surge test waveform |
| RθJL | 20 °C/W - junction-to-lead thermal resistance enabling direct PCB copper pour heat sinking without external heatsink |
| TJ(max) | 175 °C - maximum junction temperature supporting operation in under-hood automotive or industrial environments |
| Temp. Coeff. | +0.065 %/°C - positive VBR drift with temperature ensures stable clamping across operating range |

IC Role / Device Role / Timing Role: Used in discrete unidirectional configuration per line (A/B), referenced to local ground plane. Use Value: Tight VBR tolerance (±6.5 %) and low VC ensure consistent clamping across production batches, maintaining signal integrity during 1 kV/2 kA surge tests. |
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 nominal VBR; same 600 W rating but higher IPPM (64.5 A) and VC (12.7 V) | SMT-only footprint; better suited for automated assembly and higher-density layouts than DO-15 through-hole | Select SMBJ8.0A when board space is constrained and reflow capability exists; P6KE8.2A-E3/54 remains optimal for manual repair, high-voltage creepage, or legacy through-hole designs. |
| 1.5KE8.2A | Same DO-15 package; identical VBR and VWM; higher PPPM (1500 W) but larger physical size and higher VC (13.4 V) | Used where higher single-event surge margin is required (e.g., outdoor telecom cabinets), accepting larger board area and slightly higher clamping | Choose 1.5KE8.2A only if system-level testing confirms need for >600 W surge headroom; P6KE8.2A-E3/54 offers best cost/performance balance for standard industrial IEC 61000-4-5 compliance. |
Compared with SMBJ8.0A and 1.5KE8.2A, P6KE8.2A-E3/54 delivers optimal trade-off of proven DO-15 reliability, tight VBR tolerance, and cost-effective 600 W protection - making it the preferred choice for volume automotive and industrial control applications where through-hole assembly and AEC-Q101 validation are mandatory.
