Product details
Overview
P6KE120-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 114 V minimum breakdown voltage (VBR), 102 V standoff voltage (VWM), 165 V maximum clamping voltage (VC) at 3.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive body control modules to safeguard microcontrollers against load-dump transients.
For engineers reviewing the P6KE120-E3/54 datasheet, P6KE120-E3/54 pinout, P6KE120-E3/54 application, or P6KE120-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJL = 20 °C/W), RoHS-compliant DO-15 package compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P6KE120-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering unidirectional clamping action where reverse-biased conduction initiates at VBR ≥ 114 V and limits transient voltage to ≤165 V at IPPM = 3.6 A. Its 20 °C/W junction-to-lead thermal resistance enables direct PCB trace heat sinking without external heatsinks under pulsed conditions.
It complies with JEDEC JESD22-B106 solderability standards, withstands 275 °C solder dip for 10 s, and meets UL 94 V-0 flammability requirements via molded epoxy encapsulation in DO-204AC (DO-15) case. The E3 suffix confirms RoHS compliance and JESD201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 102 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets upper limit for safe DC rail operation. |
| VBR (min) | 114 V at 1 mA test current - Minimum voltage at which avalanche breakdown begins; defines turn-on threshold under transient stress. |
| VC (max) | 165 V at 3.6 A IPPM - Maximum clamped voltage during 10/1000 µs surge; determines worst-case stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability; supports robust protection against ISO 7637-2 Pulse 5a (load dump) events. |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; allows estimation of temperature rise under repetitive surges using lead traces as heat path. |
| IFSM | 100 A - Non-repetitive forward surge current rating (8.3 ms half-sine); validates survivability during accidental polarity reversal. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments with minimal derating. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with matte tin-plated leads. Cathode indicated by color band on cathode end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration; conducts during forward surge events up to 100 A. |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 12 V rail); initiates reverse breakdown at ≥114 V to shunt surge current away from sensitive loads. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5 %) and long-term reliability under thermal cycling and humidity exposure. |
| 600 W peak pulse power (10/1000 µs) | Provides immunity to high-energy transients such as ISO 7637-2 Pulse 5a (load dump) without degradation after repeated strikes. |
| AEC-Q101 qualified (E3 suffix variant) | Validates suitability for automotive applications including engine control units, body electronics, and infotainment power supplies. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during clamping, reducing risk of latch-up or gate oxide damage in protected MOSFETs and MCUs. |
| RoHS-compliant & JESD201 Class 1A whisker resistant | Supports lead-free reflow assembly and eliminates tin whisker growth risk in high-reliability industrial and automotive assemblies. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Lower PPPM (600 W same), but smaller SMB package (3.5 mm × 4.6 mm); VC = 177 V at 3.4 A; RθJA = 110 °C/W vs. 75 °C/W for P6KE120-E3/54. | Better suited for space-constrained PCBs; less effective for high-duty-cycle surges due to higher thermal resistance. | Select when board area is critical and surge repetition rate is low (<0.1 Hz). |
| 1.5KE120A | Same DO-15 package and VBR/VC specs, but higher PPPM = 1500 W; larger die size increases capacitance (≈150 pF vs. ≈50 pF for P6KE120-E3/54). | Preferred for high-energy lightning-induced surges; not ideal for high-speed data lines due to elevated junction capacitance. | Choose when protecting AC mains inputs or motor drives requiring >1 kW surge handling. |
Compared with SMBJ110A and 1.5KE120A, the P6KE120-E3/54 delivers optimal balance of automotive qualification, thermal performance in axial packages, and low capacitance - making it preferred for cost-sensitive, thermally demanding 12 V rail protection where board real estate permits DO-15 mounting.

FAQ
What is the clamping voltage of P6KE120-E3/54 at its rated peak pulse current?
The P6KE120-E3/54 has a maximum clamping voltage (VC) of 165 V when subjected to its rated peak pulse current (IPPM) of 3.6 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events. The P6KE120-E3/54 maintains this clamping performance across its specified operating temperature range.
Is P6KE120-E3/54 suitable for automotive applications?
Yes, the P6KE120-E3/54 is AEC-Q101 qualified per the Vishay datasheet (Document Number 88369, Revision 18-Sep-12), confirming its suitability for automotive use cases including body control modules, lighting drivers, and infotainment power supplies. Its 175 °C maximum junction temperature and robust surge handling make the P6KE120-E3/54 appropriate for under-hood and cabin environments.
What does the "E3/54" suffix indicate in P6KE120-E3/54?
The "E3" suffix denotes RoHS compliance and JESD201 Class 1A whisker resistance, while "/54" specifies the preferred package code for 13-inch paper tape and reel packaging with a base quantity of 4000 units. This packaging format ensures automated placement compatibility and traceable lot control - critical for high-volume manufacturing of the P6KE120-E3/54.
How does P6KE120-E3/54 differ from bi-directional TVS diodes like P6KE120CA?
The P6KE120-E3/54 is unidirectional and features a cathode band for polarity identification, enabling asymmetric clamping only in reverse bias. In contrast, P6KE120CA is bi-directional with no polarity marking and clamps symmetrically in both directions. The P6KE120-E3/54 offers lower leakage and tighter VBR tolerance than its CA counterpart, making it preferable for DC rail protection where polarity is fixed.
What is the thermal resistance of P6KE120-E3/54, and how does it affect layout design?
The P6KE120-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning each watt of dissipated surge energy raises the junction temperature by ~20 °C above lead temperature. To maximize surge endurance, PCB layout should use wide copper traces (≥2 mm width) connecting both leads to internal ground/power planes - effectively turning the P6KE120-E3/54's leads into thermal conduction paths.
