Product details
Overview
P6KE36CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 34.2 V minimum breakdown voltage (VBR), 30.8 V standoff voltage (VWM), 49.9 V maximum clamping voltage at 12.0 A peak pulse current (IPPM), 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification - used to protect MOSFETs and sensor signal lines in automotive body control modules.
For engineers reviewing the P6KE36CA-E3/54 datasheet, P6KE36CA-E3/54 pinout, P6KE36CA-E3/54 application, or P6KE36CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, low leakage (<1.0 μA at VWM), and UL 94 V-0 molded epoxy housing for industrial-grade reliability.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR (34.2–37.8 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the bidirectional structure eliminates polarity concerns in AC-coupled or differential signal paths.
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling reliable operation up to 175 °C junction temperature. The 10/1000 μs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5, with derating applied above 25 °C ambient per Figure 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30.8 V - Maximum continuous reverse operating voltage before significant leakage; sets safe margin below system rail voltage. |
| VBR min/max | 34.2 V / 37.8 V at 1.0 mA - Confirmed avalanche onset range; defines minimum overvoltage threshold for clamping activation. |
| VC @ IPPM | 49.9 V at 12.0 A - Maximum clamped voltage during 600 W transient; determines worst-case stress on protected IC inputs. |
| IPPM | 12.0 A - Peak surge current handled with 10/1000 μs waveform; validates protection against common ESD and load-dump events. |
| PPPM | 600 W - Peak pulse power rating; enables robust suppression of high-energy transients without thermal runaway. |
| TJ max | 175 °C - Maximum junction temperature; supports under-hood automotive use and high-ambient industrial environments. |
| Package | DO-15 (DO-204AC) - Standard axial-leaded through-hole package; compatible with legacy PCB layouts and wave-solder processes. |
Pinout & Package
DO-15 (DO-204AC) package: axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Bidirectional construction means no cathode marking - both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Both terminals serve identical clamping function; no polarity dependency - simplifies layout in AC or floating signal lines. |
| Lead 1 / Lead 2 | Thermal and electrical interface | Leads conduct surge current to PCB copper; RθJL = 20 °C/W requires ≥10 mm² copper pad per lead for full 600 W rating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | Same VWM/VBR/VC specs but SMC (DO-214AB) surface-mount package; 600 W rating, RθJA = 40 °C/W. | Requires PCB redesign for SMT assembly; better thermal performance in compact layouts but lacks axial-leaded mechanical robustness. | Select SMBJ36CA only if board space is constrained and reflow capability exists; P6KE36CA-E3/54 preferred for through-hole reliability and serviceability. |
| 1.5KE36CA | Same DO-15 package and electrical specs but 1500 W peak power rating; larger die size, higher IPPM (38.5 A), higher capacitance (~150 pF). | Over-spec'd for most 600 W applications; increased junction capacitance may degrade high-speed signal integrity. | Choose 1.5KE36CA only when legacy designs require backward compatibility or when surge threat level exceeds IEC 61000-4-5 Level 4. |

FAQ
What is the clamping voltage of P6KE36CA-E3/54 at its rated peak pulse current?
The P6KE36CA-E3/54 has a maximum clamping voltage (VC) of 49.9 V at 12.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during a full-rated surge event. The P6KE36CA-E3/54 maintains this clamping performance across its specified operating temperature range.
Is P6KE36CA-E3/54 suitable for automotive applications?
Yes, P6KE36CA-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including body electronics, lighting control, and infotainment power rails. Its 175 °C maximum junction temperature, glass-passivated junction, and UL 94 V-0 epoxy housing meet critical automotive reliability requirements. The P6KE36CA-E3/54 is referenced in Vishay's automotive-grade product documentation for load-dump and ESD protection.
How does the bidirectional design of P6KE36CA-E3/54 affect its circuit implementation?
The bidirectional design of P6KE36CA-E3/54 means both terminals are functionally identical - there is no anode/cathode marking, and it clamps voltage transients equally in either polarity. This eliminates orientation concerns during placement and enables direct use on AC-coupled lines, differential buses (e.g., CAN, RS-485), or ungrounded power domains. The P6KE36CA-E3/54 thus simplifies layout and reduces BOM complexity versus unidirectional alternatives.
What is the standoff voltage (VWM) of P6KE36CA-E3/54, and why is it important?
The standoff voltage (VWM) of P6KE36CA-E3/54 is 30.8 V - the maximum continuous reverse voltage it can withstand without significant leakage current (<1.0 μA). This parameter ensures the P6KE36CA-E3/54 remains non-conductive during normal operation, avoiding power loss or signal distortion, while still triggering reliably when transients exceed 34.2 V (VBR min). It directly informs system voltage margin design.
Does P6KE36CA-E3/54 have RoHS and lead-free compliance?
Yes, P6KE36CA-E3/54 carries the "E3" suffix, indicating full RoHS compliance and commercial-grade qualification per JESD 201 Class 1A whisker testing. The matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the UL 94 V-0 epoxy compound satisfies environmental and safety requirements for global electronics manufacturing.
