Product details
Overview
P6KE36A-E3/54 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 600 W peak pulse power (10/1000 μs), 34.2–37.8 V breakdown voltage at 1 mA, 30.8 V stand-off voltage, 1.0 μA max reverse leakage, and clamps to ≤49.9 V at 12.0 A peak pulse current.
For engineers reviewing the P6KE36A-E3/54 datasheet, P6KE36A-E3/54 pinout, P6KE36A-E3/54 application, or P6KE36A-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, standoff voltage compatibility with operating rail, thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and DO-15 PCB footprint constraints.
Technical Context
This TVS operates as a silicon avalanche diode, leveraging glass-passivated junction technology for stable breakdown behavior and low incremental surge resistance. Its unidirectional polarity uses a cathode band marking, and it delivers sub-nanosecond response time to suppress fast-rising transients before downstream components are damaged.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; its 5.0 W steady-state power dissipation assumes infinite heatsink at lead temperature of 75 °C. It meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 34.2 V / 37.8 V at 1.0 mA - defines minimum guaranteed clamping onset and ensures safe margin above 30.8 V operating rail |
| VWM | 30.8 V - maximum continuous reverse working voltage; must exceed system nominal supply to avoid leakage-induced power loss |
| IPPM | 12.0 A (10/1000 μs) - peak transient current it safely shunts without failure; determines required upstream fuse rating |
| VC | ≤49.9 V at IPPM - maximum clamped voltage seen by protected circuit; must stay below IC absolute maximum rating |
| PPPM | 600 W - peak pulse power handling capacity under standardized surge waveform; validates robustness against IEC 61000-4-5 Level 4 |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables accurate transient thermal modeling during repetitive surge events |
| TJ max | +175 °C - maximum allowable junction temperature; supports operation in under-hood automotive environments |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case with matte tin-plated leads. Dimensions: 3.3–3.5 mm diameter × 25.4 mm min length; lead spacing ≥6.15 mm. Compliant with UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during positive transients when cathode is biased higher |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line (e.g., 3.3 V rail or signal); avalanches into conduction when line voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable, repeatable avalanche characteristics over lifetime and temperature; eliminates surface degradation under humidity/stress |
| 600 W peak pulse power (10/1000 μs) | Validates immunity to high-energy transients per ISO 7637-2 Pulse 5a and IEC 61000-4-5 combination wave (1.2/50 μs + 8/20 μs) |
| AEC-Q101 qualified (E3 suffix variant not qualified; HE3 is) | P6KE36A-E3/54 is commercial grade; for automotive use, P6KE36AHE3/54 must be selected to meet stress test requirements |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage exposure to protected ICs-critical for 3.3 V or 5 V logic rails where margin is tight |
| Solderable per J-STD-002/JESD 22-B102 | Guarantees reliable reflow and wave solder joint integrity without lead damage or delamination |
Applications

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 (34.2–37.8 V), but SMC package (surface-mount); 600 W rating; RθJA = 40 °C/W vs. 75 °C/W for DO-15 | Requires PCB redesign for SMD footprint; better suited for automated assembly and space-constrained boards | Select SMBJ36A only if board layout supports SMC package and thermal management accommodates higher RθJA |
| 1.5KE36A | Same DO-15 package and electrical specs, but 1.5 kW peak power (10/1000 μs); larger die size; higher IPPM (33.3 A) | Overqualified for 600 W needs; higher cost and capacitance; may cause excessive crowbar current in low-impedance circuits | Choose 1.5KE36A only when legacy designs require backward compatibility or surge margin beyond 600 W is mandated |
Compared with SMBJ36A and 1.5KE36A, P6KE36A-E3/54 offers optimal balance of proven DO-15 reliability, cost efficiency, and precise 600 W surge handling-ideal for volume consumer and industrial applications where leaded assembly and thermal budget are primary constraints.

FAQ
What is the breakdown voltage range of the P6KE36A-E3/54?
The P6KE36A-E3/54 has a guaranteed breakdown voltage (VBR) range of 34.2 V to 37.8 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent clamping onset across production lots and provides design margin above its 30.8 V stand-off voltage. The P6KE36A-E3/54 must be selected only when system operating voltage remains below 30.8 V to prevent premature conduction.
Is the P6KE36A-E3/54 AEC-Q101 qualified?
No, the P6KE36A-E3/54 is commercial-grade and RoHS-compliant (E3 suffix), but not AEC-Q101 qualified. For automotive applications requiring qualification, the P6KE36AHE3/54 variant must be used-it carries the HE3 suffix and meets AEC-Q101 stress test requirements including HTGB, HTRB, and temperature cycling. The P6KE36A-E3/54 itself is intended for industrial, consumer, and telecom systems where qualification is not mandated.
What is the maximum clamping voltage of the P6KE36A-E3/54 at rated peak pulse current?
The P6KE36A-E3/54 clamps to a maximum of 49.9 V at its rated peak pulse current (IPPM) of 12.0 A under the standard 10/1000 μs waveform. This value is specified in the Electrical Characteristics table and represents the worst-case voltage imposed on the protected circuit during surge events. Designers must verify that this clamped voltage stays below the absolute maximum rating of downstream ICs-especially critical for 3.3 V or 5 V logic interfaces.
Can the P6KE36A-E3/54 be used in bidirectional configurations?
No, the P6KE36A-E3/54 is strictly unidirectional, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6KE36CA). Using P6KE36A-E3/54 in bidirectional applications would result in forward conduction during negative transients, causing failure or unintended shorting. For AC-coupled or dual-polarity signal lines, P6KE36CA or equivalent bidirectional TVS must be selected instead of P6KE36A-E3/54.
What is the thermal resistance from junction to lead for the P6KE36A-E3/54?
The P6KE36A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in the Thermal Characteristics table. This parameter enables accurate estimation of junction temperature rise during repetitive surge events when lead temperature is known. It is distinct from RθJA (75 °C/W), which applies to still-air ambient conditions and is less relevant for high-duty-cycle applications where heat flows primarily through the leads.
