Product details
Overview
P6KE220A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for overvoltage protection of sensitive electronics. 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 - deployed in power supply input stages, DC bus lines, and industrial I/O interfaces.
For engineers reviewing the P6KE220A-E3/54 datasheet, P6KE220A-E3/54 pinout, P6KE220A-E3/54 application, or P6KE220A-E3/54 equivalent, key selection criteria include verified clamping performance under 1.8 A transient surge, DO-15 package thermal resistance (RθJL = 20 °C/W), unidirectional polarity with cathode band marking, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (185 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), critical for suppressing ESD and inductive switching transients.
The device sustains 600 W peak pulse power (10/1000 μs) with 0.01 % duty cycle, dissipates 5.0 W continuously on infinite heatsink at TL = 75 °C, and supports 100 A non-repetitive forward surge (8.3 ms half-sine). Junction temperature range spans –55 °C to +175 °C, enabling operation in harsh industrial and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 209 V / 231 V at 1.0 mA test current - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 185 V maximum - ensures no conduction during normal 175–185 V DC operating conditions |
| VC at IPPM | 328 V at 1.8 A - limits protected circuit voltage to safe level during worst-case transient |
| PPPM | 600 W with 10/1000 μs waveform - withstands high-energy surges common in motor drives and power supplies |
| RθJL | 20 °C/W - enables effective heat transfer from junction to lead for sustained surge handling |
| TJ max | +175 °C - supports operation in under-hood automotive and high-temperature industrial enclosures |
| IFSM | 100 A (8.3 ms half-sine) - handles repetitive inrush or fault currents without degradation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Same VWM/VBR/VC specs but SMB package (smaller footprint, higher RθJA = 110 °C/W) | Better suited for space-constrained PCBs; requires tighter thermal layout due to lower power dissipation margin | Select SMBJ220A only if board area is critical and surge duty cycle remains <0.01 % |
| 1.5KE220A | Same DO-15 package but higher 1500 W PPPM; larger die size increases capacitance (≈150 pF vs. ≈50 pF) | Preferred for high-energy lightning surges; less suitable for high-speed data lines due to higher junction capacitance | Choose 1.5KE220A when protecting AC mains inputs or legacy industrial systems with >1 kV surge requirements |
Compared with SMBJ220A and 1.5KE220A, P6KE220A-E3/54 delivers optimal balance of surge robustness (600 W), thermal performance (RθJL = 20 °C/W), and low capacitance for DC power rail protection - making it ideal for cost-sensitive, thermally managed automotive and industrial designs where DO-15 mounting is standard.

FAQ
What is the clamping voltage of P6KE220A-E3/54 under maximum rated surge current?
The P6KE220A-E3/54 has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream components experience no more than 328 V during specified transient events. The clamping performance is validated across –55 °C to +175 °C operating junction temperatures, ensuring consistent protection in extreme environments. P6KE220A-E3/54 maintains this specification without derating up to TA = 25 °C.
Is P6KE220A-E3/54 suitable for automotive applications?
Yes, P6KE220A-E3/54 is AEC-Q101 qualified per the Vishay datasheet (Document Number: 88369), confirming compliance with stress tests for automotive powertrain and body electronics. Its 175 °C maximum junction temperature, 100 A IFSM, and DO-15 mechanical robustness meet requirements for under-hood and chassis-mounted modules. P6KE220A-E3/54 is explicitly listed for use in automotive power distribution systems, including battery-connected ECUs subjected to ISO 7637-2 load dump pulses.
How does the DO-15 package of P6KE220A-E3/54 affect thermal performance?
The DO-15 (DO-204AC) package of P6KE220A-E3/54 provides a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer to PCB copper pours or heatsinks. Unlike surface-mount alternatives, its axial-leaded construction allows direct lead soldering to thermal vias or metal-core boards. P6KE220A-E3/54 achieves 5.0 W continuous power dissipation at TL = 75 °C, making it suitable for high-reliability linear regulator inputs and DC bus monitoring circuits where thermal mass matters.
What is the standoff voltage rating for P6KE220A-E3/54, and how does it relate to system operating voltage?
P6KE220A-E3/54 has a maximum standoff voltage (VWM) of 185 V, meaning it remains non-conductive up to this DC or RMS voltage. This allows safe integration into 175–185 V DC systems such as telecom rectifier outputs or industrial 200 V nominal buses. Engineers must ensure system operating voltage stays ≥10 % below VWM to avoid leakage-related power loss; P6KE220A-E3/54 exhibits only 1.0 μA max reverse leakage at 185 V, minimizing standby current impact.
Does P6KE220A-E3/54 have bidirectional capability?
No, P6KE220A-E3/54 is a unidirectional TVS diode, as indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6KE220CA). The unidirectional configuration of P6KE220A-E3/54 provides lower forward voltage drop (VF = 3.5 V at 50 A) and tighter VBR tolerance for DC rail protection. For AC-coupled signal lines or differential bus protection, a CA-series part would be required - P6KE220A-E3/54 is optimized exclusively for single-polarity DC overvoltage suppression.
