Product details
Overview
P6KE36AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features 34.2 V minimum breakdown voltage (VBR), 30.8 V maximum stand-off voltage (VWM), 49.9 V clamping voltage (VC) at 12.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor signal lines and industrial I/O protection.
For engineers reviewing the P6KE36AHE3/54 datasheet, P6KE36AHE3/54 pinout, P6KE36AHE3/54 application, or P6KE36AHE3/54 equivalent, key selection criteria include verified AEC-Q101 qualification, DO-15 mechanical compatibility, bidirectional variant availability (P6KE36CAHE3/54), and thermal resistance (RθJL = 20 °C/W) for PCB-level surge energy dissipation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at 30.8 V), then rapidly avalanches below 49.9 V when transient exceeds VBR, diverting up to 12.0 A (10/1000 μs) away from downstream ICs. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for unidirectional DC line protection, it supports 100 A non-repetitive forward surge current (8.3 ms half-sine), operates from –55 °C to +175 °C junction temperature, and meets JESD 22-B102 solderability and JESD 201 Class 2 whisker resistance requirements due to its HE3 suffix.
Key Specifications

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine control modules exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between sensor VOUT and chassis ground to clamp transients before reaching ADC input. Use Value: Limits voltage seen by downstream op-amp and SAR ADC to ≤49.9 V, preserving measurement integrity and preventing input stage damage. | Use Scenario: Safeguarding 24 V digital input channels on programmable logic controller (PLC) backplanes subject to field-wiring induced surges. IC Role / Device Role / Timing Role: Standoff voltage (30.8 V) exceeds nominal 24 V DC bus while clamping fast-rising transients (<1 ns) on discrete optocoupler inputs. Use Value: Enables reliable operation without external series resistors or RC filters, reducing BOM count and board space. |
| Consumer Power Adapter Input | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters where rectified DC rails may experience switching spikes or capacitor discharge events. IC Role / Device Role / Timing Role: Mounted across bulk capacitor terminals to absorb stored energy during MOSFET turn-off or transformer leakage spikes.

Use Value: Maintains signal integrity up to 10 Mbps while limiting line voltage to safe levels for transceiver ESD structures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36AHE3/52 | Same VWM/VBR/VC specs but SMB package (smaller footprint, higher RθJA = 110 °C/W) | Better suited for space-constrained consumer boards; lower thermal mass reduces single-pulse energy handling margin | Select when PCB area is critical and surge duty cycle is low; verify trace width for 12 A pulse current |
| P6KE36CAHE3/54 | Bidirectional version with identical VBR (34.2–37.8 V) and VC (49.9 V), no polarity marking | Required for AC-coupled or floating signal lines (e.g., audio, Ethernet PHY) where voltage polarity reverses | Choose only when protecting symmetric signals; unidirectional P6KE36AHE3/54 offers tighter leakage control for DC bias rails |
Compared with SMBJ36AHE3/52 and P6KE36CAHE3/54, the P6KE36AHE3/54 provides optimal thermal performance in DO-15 for high-reliability industrial use, retains polarity identification for correct placement, and delivers proven AEC-Q101 compliance without derating for automotive ambient temperatures.

FAQ
What is the meaning of the 'HE3' suffix in P6KE36AHE3/54?
The HE3 suffix in P6KE36AHE3/54 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. This distinguishes it from commercial-grade E3 variants and confirms suitability for automotive applications requiring extended temperature operation and enhanced mechanical reliability. The P6KE36AHE3/54 meets all stress tests defined in AEC-Q101 Rev D, including HTGB, HTRB, and TCT.
How does P6KE36AHE3/54 differ from P6KE36A-E3/54?
P6KE36AHE3/54 is AEC-Q101 qualified and rated for automotive use, whereas P6KE36A-E3/54 is commercial grade only. Both share identical electrical parameters (VBR, VC, PPPM) and DO-15 packaging, but the HE3 variant undergoes additional reliability testing including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing. The P6KE36AHE3/54 is specified for operation up to +175 °C junction temperature with validated lifetime performance under automotive conditions.
Can P6KE36AHE3/54 be used in bidirectional signal protection?
No - P6KE36AHE3/54 is strictly unidirectional and must be oriented with cathode toward the protected line. For bidirectional protection, the designated variant is P6KE36CAHE3/54, which has symmetrical breakdown in both directions and no polarity marking. Using P6KE36AHE3/54 on AC or floating lines risks forward conduction during negative half-cycles, leading to excessive leakage or thermal runaway. Always match device polarity to circuit topology.
What is the maximum clamping voltage of P6KE36AHE3/54 at its rated peak pulse current?
The maximum clamping voltage (VC) of P6KE36AHE3/54 is 49.9 V at 12.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events. It is measured after the device enters avalanche conduction and reflects worst-case voltage seen by downstream components when P6KE36AHE3/54 is correctly applied in series with appropriate current-limiting impedance.
Is P6KE36AHE3/54 compatible with lead-free reflow soldering processes?
Yes - P6KE36AHE3/54 is qualified for lead-free reflow soldering with peak temperatures up to 260 °C per JEDEC J-STD-020. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and the epoxy molding compound withstands multiple reflow cycles without delamination or parameter shift. The P6KE36AHE3/54 also passes JESD 201 Class 2 whisker testing, ensuring long-term interconnect reliability in Pb-free assemblies.
