Product details
Overview
P6KE220-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 209 V minimum breakdown voltage (VBR), 185 V maximum standoff voltage (VWM), 328 V clamping voltage (VC) at 1.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the P6KE220-E3/54 datasheet, P6KE220-E3/54 pinout, P6KE220-E3/54 application, or P6KE220-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 matte tin plating, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, responding to transients in <1 ps with low incremental surge resistance. Its unidirectional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 50 A, enabling robust surge handling without latch-up in DC-biased protection paths.
The P6KE220-E3/54 is rated for -55 °C to +175 °C operating junction temperature, derates linearly above 25 °C ambient per Fig. 2, and delivers stable clamping performance across repetitive 0.01% duty cycle pulses - critical for protecting MOSFET gate drivers and microcontroller I/O against inductive switching spikes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 185 V - maximum continuous DC or RMS voltage before conduction begins; sets upper limit for protected circuit's normal operating voltage |
| VBR (Breakdown) | 209–231 V at 1 mA - guaranteed avalanche initiation range; ensures reliable turn-on before downstream component damage threshold |
| VC (Clamping) | 328 V at 1.8 A (10/1000 µs) - maximum voltage seen by protected load during surge; defines worst-case stress on downstream ICs |
| PPPM | 600 W - peak transient energy absorption capacity; supports single-event surges up to 600 W without failure |
| IFSM | 100 A (8.3 ms half-sine) - non-repetitive forward surge rating; validates robustness against accidental reverse polarity or high-current faults |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables accurate PCB copper pour sizing for sustained 5 W power dissipation at TL = 75 °C |
| TJ max | +175 °C - maximum junction temperature; allows operation in under-hood automotive environments without thermal shutdown |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, molded epoxy case meeting UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to ground or low-side return path in unidirectional configuration; must be routed with low-inductance trace for effective clamping |
| Cathode (banded end) | Avalanche conduction terminal | Connected to protected line (e.g., 24 V rail); color band identifies polarity - critical for correct installation in series with fuse or upstream filter |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable VBR tolerance (±5%) and long-term reliability under humidity and thermal cycling per JESD22-A101 |
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when combined with appropriate series impedance |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive powertrain and body electronics applications requiring zero defect rates over 15-year service life |
| Low clamping ratio (VC/VBR ≈ 1.57) | Minimizes overvoltage margin needed between protected IC's VDD max and TVS clamping level - reduces design safety factor overhead |
| Solder dip rated 275 °C / 10 s | Ensures compatibility with lead-free reflow profiles and wave soldering without delamination or parameter shift |
Applications

IC Role / Device Role / Timing Role: First-stage TVS on primary DC bus, coordinated with gas discharge tube (GDT) for staged protection. Use Value: Absorbs initial 600 W surge energy before GDT fires, reducing let-through voltage to <400 V and extending system-level surge lifetime. |
Use Scenario: Brushed DC motor control boards in washing machines experiencing commutation spikes up to 300 V during brush arcing. IC Role / Device Role / Timing Role: Snubber-connected TVS across motor terminals to suppress inductive kickback before reaching H-bridge MOSFETs. Use Value: Limits flyback voltage to 328 V, keeping MOSFETs within SOA and eliminating need for higher-voltage (and higher-RDS(on)) devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Same VWM/VBR/VC specs but SMC (DO-214AB) package; 100 W lower PPPM (500 W) | Higher board density required; better suited for space-constrained consumer PCBs than industrial chassis-mount designs | Select SMBJ220A only if footprint reduction outweighs 100 W pulse power margin loss and thermal mass requirements permit |
| 1.5KE220A | Same electrical specs but larger DO-201AD package; identical 600 W rating and 209–231 V VBR | Higher thermal mass (RθJA ≈ 15 °C/W vs. 75 °C/W for P6KE220-E3/54) supports longer surge duration tolerance | Choose 1.5KE220A where extended 8.3 ms surge handling or legacy DO-201AD footprint compatibility is mandatory |

FAQ
What is the clamping voltage of the P6KE220-E3/54 at its rated peak pulse current?
The P6KE220-E3/54 has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number 88369, page 2) and defines the upper voltage limit imposed on protected circuitry during surge events. Designers must ensure this clamping level remains below the absolute maximum voltage rating of downstream components. The P6KE220-E3/54 achieves this with low incremental surge resistance and fast avalanche response.
Is the P6KE220-E3/54 suitable for automotive applications?
Yes, the P6KE220-E3/54 is AEC-Q101 qualified per the Vishay datasheet (footnote on page 3), confirming its suitability for automotive powertrain and body electronics. Its -55 °C to +175 °C operating junction temperature range, glass-passivated junction, and RoHS-compliant matte tin plating meet stringent automotive reliability requirements. The P6KE220-E3/54 is commonly deployed in engine control units and lighting modules where load dump and jump-start transients occur.
How does the P6KE220-E3/54 differ from bi-directional TVS diodes like P6KE220CA?
The P6KE220-E3/54 is unidirectional and features a cathode band for polarity identification, while P6KE220CA is bi-directional with no marking and symmetrical clamping in both directions. Unidirectional operation allows the P6KE220-E3/54 to provide lower forward voltage (3.5 V at 50 A) and tighter VBR tolerance in DC-biased applications such as power rail protection. The P6KE220-E3/54 is not interchangeable with P6KE220CA without circuit redesign due to polarity and conduction behavior differences.
What is the thermal resistance of the P6KE220-E3/54, and how does it affect PCB layout?
The P6KE220-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in the Vishay datasheet (page 3, Thermal Characteristics table). This value guides PCB copper pour sizing: for continuous 5 W dissipation at TL = 75 °C, designers must ensure adequate copper area and via count to maintain lead temperature within limits. Unlike RθJA, RθJL reflects conduction path to the leads - making it the relevant metric for through-hole mounting with heatsinked traces. The P6KE220-E3/54 benefits from wide, short copper spokes connected to both leads.
Can the P6KE220-E3/54 be used in AC line protection?
No, the P6KE220-E3/54 is not rated for AC line protection. Its 185 V maximum standoff voltage (VWM) is intended for DC or rectified DC applications; applying it directly across 120/230 V AC mains would cause continuous conduction and thermal failure. For AC line protection, bi-directional variants like P6KE220CA or purpose-built AC-rated TVS devices with higher VWM and isolation ratings are required. The P6KE220-E3/54 is strictly for DC power rail and low-voltage signal line protection.
