Product details
Overview
P6KE39CA-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 37.1 V minimum and 41.0 V maximum breakdown voltage at 1.0 mA test current, 33.3 V standoff voltage, 1.0 μA max reverse leakage at VWM, 11.1 A peak pulse current (10/1000 μs), and 53.9 V max clamping voltage at IPPM - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE39CA-E3/54 datasheet, P6KE39CA-E3/54 pinout, P6KE39CA-E3/54 application, or P6KE39CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, 600 W peak pulse power rating, DO-15 mechanical compatibility, AEC-Q101 qualification status (via HE3 variant), and thermal resistance of 20 °C/W junction-to-lead.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bidirectional CA construction. Its 10/1000 μs waveform response enables suppression of inductive switching spikes and lightning-induced surges without polarity sensitivity.
Thermal performance is defined by RθJL = 20 °C/W and RθJA = 75 °C/W, supporting operation from –55 °C to +175 °C junction temperature. The 5.0 W steady-state power dissipation at TL = 75 °C and 100 A IFSM rating confirm robust surge handling under repetitive or single-event stress conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 37.1 V / 41.0 V at IT = 1.0 mA - defines reliable avalanche initiation range for transient detection |
| VWM | 33.3 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 53.9 V at 11.1 A (10/1000 μs) - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capacity under standardized surge waveform |
| ID @ VWM | ≤ 1.0 μA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | +175 °C - enables deployment in under-hood automotive or high-temperature industrial environments |
| RθJL | 20 °C/W - supports thermal management with standard PCB copper pour or lead-frame heatsinking |
Pinout & Package
Package: DO-15 (DO-204AC), 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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Accepts reverse surge current during negative transients; symmetric with cathode in bidirectional operation |
| Cathode | Transient current entry (positive polarity) | Accepts reverse surge current during positive transients; no color band marking per bidirectional designation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable avalanche characteristics and long-term reliability under repeated surge stress |
| 600 W peak pulse power (10/1000 μs) | Supports protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) in compact form factor |
| AEC-Q101 qualified (HE3 variant) | Validated for automotive powertrain and body electronics applications requiring zero defect reliability |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (< 1 ns response time implied by TVS architecture) |
| Solder dip rated 275 °C for 10 s | Ensures compatibility with lead-free reflow and wave soldering processes without parametric shift |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |

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 | DO-214AA package; 36 V VWM; 58.1 V VC @ 10.3 A; 600 W PPPM | Surface-mount footprint; lower clamping voltage but reduced thermal mass vs. axial DO-15 | Select when board space is constrained and automated SMT assembly is required |
| 1.5KE39CA | DO-201AD package; identical VBR/VWM/VC specs; same 600 W rating; higher IFSM (200 A) | Larger axial package with improved surge endurance; not AEC-Q101 qualified | Select for non-automotive industrial applications requiring higher single-pulse surge margin |
Compared with P6KE39CA-E3/54, SMBJ36CA offers SMT compatibility at the cost of lower thermal inertia, while 1.5KE39CA delivers higher surge current tolerance in a larger axial package but lacks automotive qualification - making P6KE39CA-E3/54 optimal for cost-sensitive, AEC-Q101-aligned designs with DO-15 layout constraints.

FAQ
What is the clamping voltage of the P6KE39CA-E3/54 under maximum surge conditions?
The P6KE39CA-E3/54 exhibits a maximum clamping voltage (VC) of 53.9 V when subjected to its rated peak pulse current of 11.1 A using the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on the protected circuit during transient events, ensuring downstream components remain within safe operating limits.
Is the P6KE39CA-E3/54 suitable for automotive applications?
The P6KE39CA-E3/54 is RoHS-compliant and based on the P6KE family, which includes AEC-Q101-qualified variants (e.g., P6KE39CAHE3/54). While the -E3 suffix denotes commercial grade, the underlying design and DO-15 construction meet automotive environmental stress requirements - system-level qualification should be performed per vehicle manufacturer specifications when using P6KE39CA-E3/54 in automotive contexts.
How does the bidirectional configuration of P6KE39CA-E3/54 affect its circuit placement?
The bidirectional nature of P6KE39CA-E3/54 eliminates polarity concerns during placement: it functions identically regardless of orientation across a differential or single-ended line. Unlike unidirectional TVS diodes, P6KE39CA-E3/54 has no cathode marking and provides symmetrical clamping for both positive and negative transients - simplifying layout and reducing BOM complexity in AC-coupled or floating signal paths.
What is the thermal resistance profile of P6KE39CA-E3/54, and how does it impact PCB layout?
P6KE39CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. Effective heat dissipation relies on adequate copper area connected to both leads; increasing trace width and adding thermal vias beneath the DO-15 body significantly improves sustained power handling beyond the 5.0 W rating at TL = 75 °C.
Can P6KE39CA-E3/54 replace P6KE39A in existing designs?
No - P6KE39CA-E3/54 is bidirectional, whereas P6KE39A is unidirectional. Substituting them requires verifying circuit polarity, grounding scheme, and transient directionality. Unidirectional P6KE39A includes a cathode band and conducts forward current up to 3.5 V at 50 A; P6KE39CA-E3/54 blocks in both directions until breakdown, making direct replacement unsafe without schematic and layout review.
