Product details
Overview
P6KE36-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 36 V nominal breakdown voltage (VBR = 34.2–37.8 V at IT = 1.0 mA), 49.9 V maximum clamping voltage (VC) at 12.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform. It is used in automotive body control modules to protect LIN bus transceivers from load-dump and inductive switching transients.
For engineers reviewing the P6KE36-E3/54 datasheet, P6KE36-E3/54 pinout, P6KE36-E3/54 application, or P6KE36-E3/54 equivalent, key selection criteria include its DO-204AC (DO-15) package compatibility, 30.8 V stand-off voltage (VWM), 1.0 µA max reverse leakage at VWM, AEC-Q101 qualification status, and thermal resistance (RθJL = 20 °C/W) for lead-mounted thermal management.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 GΩ) below VWM = 30.8 V, then rapidly avalanches near VBR to limit transient energy. Its glass-passivated junction enables stable breakdown characteristics and low incremental surge resistance (<0.5 Ω typical).
The device responds within <1.0 ns to ESD or lightning-induced surges and sustains repetitive 10/1000 µs pulses at 0.01% duty cycle. It is rated for operation from −55 °C to +175 °C junction temperature and meets UL 497B recognition (QVGQ2) for telecom and industrial protectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V at 1.0 mA test current - defines reliable avalanche initiation threshold for overvoltage detection |
| VWM | 30.8 V - maximum continuous working voltage before leakage exceeds 1.0 µA; sets safe DC rail margin |
| VC @ IPPM | 49.9 V at 12.0 A - clamping voltage during worst-case 600 W transient; determines protected IC's voltage stress |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform; supports automotive ISO 7637-2 Pulse 1/2a/5a immunity |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pour heatsinking without external heatsink |
| IFSM | 100 A - non-repetitive forward surge rating (8.3 ms half-sine); validates robustness against accidental polarity reversal |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by color band on unidirectional variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage return path; forms shunt path during overvoltage events |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 24 V supply rail); avalanche conduction occurs from cathode to anode |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5%) and long-term reliability under thermal cycling and humidity |
| 600 W peak pulse power (10/1000 µs) | Supports EN 61000-4-5 Level 4 (4 kV) surge immunity without derating in standard PCB layouts |
| AEC-Q101 qualified (E3 suffix) | Validated for automotive under-hood applications including engine control units and lighting drivers |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes voltage overshoot across protected ICs, reducing risk of latch-up or gate oxide damage |
| RoHS-compliant, JESD 201 Class 1A whisker tested | Enables use in high-reliability consumer and industrial assemblies with no tin-whisker mitigation required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Same VBR range (36.0–40.0 V), but SMB package (surface-mount); lower RθJA (50 °C/W vs. 75 °C/W) | Requires PCB rework for SMT assembly; better suited for space-constrained board designs | Select SMBJ36A when automated placement and smaller footprint are prioritized over through-hole serviceability. |
| 1.5KE36A | Same DO-204AC package and VBR, but higher PPPM = 1500 W; larger die size increases capacitance (≈150 pF vs. ≈50 pF) | Higher clamping voltage (58.1 V) reduces protection margin; unsuitable for fast-edge signal lines | Choose 1.5KE36A only when surge energy exceeds 600 W and signal bandwidth is not critical. |
Compared with SMBJ36A and 1.5KE36A, P6KE36-E3/54 delivers optimal balance of through-hole manufacturability, low clamping voltage (49.9 V), and AEC-Q101 qualification-making it preferred for cost-sensitive, thermally managed automotive and industrial power rail protection where layout flexibility and qualification traceability are essential.

FAQ
What is the maximum clamping voltage of the P6KE36-E3/54 under full-rated surge current?
The P6KE36-E3/54 exhibits a maximum clamping voltage (VC) of 49.9 V when subjected to its rated peak pulse current of 12.0 A (10/1000 µs waveform). This value is measured per JEDEC standards and guarantees that protected downstream circuitry remains below critical overvoltage thresholds during standardized surge events. The P6KE36-E3/54 maintains this performance across its full operating temperature range (−55 °C to +175 °C).
Is the P6KE36-E3/54 suitable for automotive applications?
Yes, the P6KE36-E3/54 is AEC-Q101 qualified (as indicated by the HE3 suffix option) and rated for junction temperatures up to +175 °C-making it suitable for under-hood automotive applications such as body control modules, lighting drivers, and LIN/CAN node protection. The P6KE36-E3/54 meets UL 497B recognition (QVGQ2) and supports ISO 7637-2 Pulse 1, 2a, and 5a test profiles when properly mounted with adequate copper area.
How does the P6KE36-E3/54 differ from bi-directional TVS variants like P6KE36CA?
The P6KE36-E3/54 is unidirectional and features a cathode band for polarity identification; it blocks reverse voltage up to 30.8 V (VWM) and conducts only during positive overvoltage events on the cathode. In contrast, P6KE36CA is bi-directional with symmetrical clamping in both polarities and no polarity marking. The P6KE36-E3/54 offers lower leakage (<1.0 µA) and tighter VBR tolerance than its CA counterpart, making it preferred for DC rail protection where reverse conduction is undesirable.
What is the thermal resistance specification for the P6KE36-E3/54, and how does it impact PCB layout?
The P6KE36-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning each watt dissipated raises the junction temperature 20 °C above the lead temperature. To maintain reliability during repetitive surges, PCB layout must provide ≥10 mm² of 2-oz copper connected directly to each lead. This thermal path allows the P6KE36-E3/54 to sustain its 600 W rating without external heatsinking and avoids exceeding the 175 °C maximum junction temperature.
Can the P6KE36-E3/54 be used in parallel for higher surge current handling?
No, the P6KE36-E3/54 should not be paralleled due to inherent VBR mismatch (±5% tolerance), which causes uneven current sharing and potential thermal runaway. For higher surge capability, select a single higher-rated device such as 1.5KE36A (1500 W) or use a hybrid protection scheme with upstream current limiting. The P6KE36-E3/54 is characterized and qualified as a standalone device; parallel operation voids AEC-Q101 compliance and violates Vishay's recommended usage guidelines.
