Product details
Overview
P6KE36A-E3/73 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 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, 600 W peak pulse power rating (10/1000 μs), and DO-15 package - used in automotive power supply input stages, industrial sensor interfaces, and telecom line card surge protection.
For engineers reviewing the P6KE36A-E3/73 datasheet, P6KE36A-E3/73 pinout, P6KE36A-E3/73 application, or P6KE36A-E3/73 equivalent, key selection criteria include clamping performance under 10/1000 μs transients, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, AEC-Q101 qualification status, and compatibility with manual or wave soldering per J-STD-002.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (30.8 V), it transitions from high-impedance blocking to low-impedance conduction at VBR (34.2–37.8 V), limiting transient energy via controlled avalanche breakdown. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and repeatable clamping behavior across temperature.
Designed for single-pulse and low-duty-cycle surge events, it delivers 600 W peak pulse power with 10/1000 μs waveform, derates linearly above 25 °C ambient (per Fig. 2), and withstands 100 A non-repetitive forward surge (8.3 ms half-sine). The DO-15 package supports lead-free reflow and wave soldering up to 275 °C for 10 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30.8 V maximum - defines highest continuous DC or RMS voltage the device blocks without conduction |
| VBR @ IT = 1.0 mA | 34.2–37.8 V - breakdown threshold where avalanche conduction begins; ensures reliable triggering before system damage |
| VC @ IPPM = 12.0 A | 49.9 V - maximum clamped voltage during 10/1000 μs transient; determines protected circuit's worst-case overvoltage stress |
| PPPM | 600 W - peak transient energy absorption capability; enables protection against IEC 61000-4-5 Level 4 surges |
| IPPM | 12.0 A - corresponding peak pulse current at VC; used to size series impedance and verify margin vs. system fault current |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; critical for estimating temperature rise during repetitive pulses or sustained power dissipation |
| TJ max. | +175 °C - maximum operating junction temperature; supports under-hood automotive and high-ambient industrial use |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads. Cathode indicated by color band on body end.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | DO-214AA package; 36.0–40.0 V VBR; 58.1 V VC @ 10.3 A; 600 W rating; lower RθJA (50 °C/W) | Surface-mount alternative with higher power density but requires PCB rework; better suited for high-volume SMT production | Select SMBJ36A when board space is constrained and SMT assembly is available; P6KE36A-E3/73 preferred for through-hole legacy designs or manual repairability. |
| 1.5KE36A | Same DO-15 package; identical VWM/VBR/VC specs; 1500 W peak power (10/1000 μs); higher IPPM (41.4 A) | Higher-energy surge handling; larger junction area increases thermal mass but reduces surge cycle life at same peak current | Choose 1.5KE36A only if system-level testing confirms need for >600 W capability; P6KE36A-E3/73 offers optimal cost/performance balance for standard automotive and industrial transients. |
Compared with SMBJ36A and 1.5KE36A, P6KE36A-E3/73 delivers verified 600 W clamping performance in a cost-optimized through-hole package with AEC-Q101 qualification, making it ideal for mid-tier surge protection where reliability, serviceability, and qualification compliance are prioritized over ultra-high energy or SMT density.

FAQ
What is the maximum clamping voltage of the P6KE36A-E3/73 under a 10/1000 μs transient?
The P6KE36A-E3/73 has a maximum clamping voltage (VC) of 49.9 V when subjected to its rated peak pulse current of 12.0 A with a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88369 and defines the upper voltage limit imposed on the protected circuit during surge events. Engineers must ensure downstream components tolerate this clamped level with margin.
Is the P6KE36A-E3/73 suitable for automotive applications?
Yes, the P6KE36A-E3/73 is AEC-Q101 qualified (as confirmed by the HE3 suffix variant and note in the datasheet), and its construction - including glass-passivated junction, -55 °C to +175 °C operating range, and DO-15 mechanical robustness - meets automotive environmental requirements. While the E3 suffix denotes commercial grade, the underlying die and process are qualified, making P6KE36A-E3/73 widely deployed in non-safety-critical automotive modules such as body control units and infotainment power supplies.
How does the P6KE36A-E3/73 differ from bidirectional TVS diodes like P6KE36CA?
The P6KE36A-E3/73 is unidirectional and features a cathode band for polarity identification, allowing it to block forward voltage up to ~3.5 V while clamping reverse transients above 30.8 V. In contrast, P6KE36CA is bidirectional with symmetrical clamping in both directions and no polarity marking. Use P6KE36A-E3/73 on DC rails where polarity is fixed; choose P6KE36CA only for AC-coupled or floating signal lines requiring dual-polarity protection.
What is the thermal resistance from junction to lead (RθJL) for the P6KE36A-E3/73?
The P6KE36A-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in the Thermal Characteristics table of Vishay document 88369. This parameter is critical for estimating temperature rise during repetitive surge events or elevated ambient conditions and informs heatsinking decisions when used in high-duty-cycle applications.
Can the P6KE36A-E3/73 be used in place of the older P6KE36A without design changes?
Yes, the P6KE36A-E3/73 is a direct replacement for P6KE36A with identical electrical specifications, DO-15 mechanical outline, and enhanced process controls. The "E3/73" suffix indicates RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 1A whisker resistance, and packaging in 73 mm tape-and-reel - all backward compatible with legacy P6KE36A layouts, soldering profiles, and functional requirements.
