Product details
Overview
P4KE8.2A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on DC power rails and signal lines. It features 7.79 V to 8.61 V breakdown voltage (VBR) at 10 mA, 7.02 V stand-off voltage (VWM), 12.1 V maximum clamping voltage (VC) at 33.1 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the P4KE8.2A-E3/54 datasheet, P4KE8.2A-E3/54 pinout, P4KE8.2A-E3/54 application, or P4KE8.2A-E3/54 equivalent, key selection criteria include clamping performance under 33.1 A surge, thermal resistance (RθJL = 66 °C/W), AEC-Q101 qualification status, DO-41 mechanical compatibility, and 200 µA max reverse leakage at VWM.
Technical Context
This TVS diode operates as a voltage-clamping protection device in parallel with sensitive circuit nodes. Its glass-passivated junction enables fast response (<1 ns) to ESD and lightning-induced transients, while its unidirectional polarity (cathode marked) supports DC-biased rail protection without forward conduction during normal operation.
The device complies with AEC-Q101 for automotive-grade reliability and uses a DO-41 (DO-204AL) epoxy-molded package rated UL 94 V-0. Thermal design must account for RθJA = 100 °C/W (lead length 10 mm) and derating above 25 °C ambient per Fig. 2 and Fig. 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 7.79 V / 8.61 V at 10 mA - defines precise clamping initiation threshold under standardized test conditions |
| VWM | 7.02 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 12.1 V at 33.1 A - clamped voltage seen by protected circuit during worst-case 10/1000 µs transient |
| IPPM | 33.1 A - peak surge current capability with 400 W pulse power, defining protection margin against IEC 61000-4-5 Level 4 |
| ID @ VWM | 200 µA - low leakage ensures minimal standby power loss and no interference with high-impedance sensing |
| TJ max | +175 °C - enables operation in under-hood automotive environments and industrial enclosures without derating |
| RθJL | 66 °C/W - critical for PCB copper pour design to maintain junction temperature below limit during repetitive surges |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, epoxy-molded body with matte tin-plated leads. Cathode indicated by color band; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Forward current entry / low-side connection | Connected to ground or lower-potential node in unidirectional configuration; must be routed with low-inductance path for effective clamping |
| Cathode (banded lead) | Reverse-biased clamping node / high-side connection | Connected to protected line (e.g., +5 V rail); reverse breakdown initiates clamping when VLINE exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables <1 ns response time and stable VBR over lifetime, critical for ESD immunity per IEC 61000-4-2 |
| 400 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 surge events up to 4 kV (line-to-earth) in industrial power supplies |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including body control modules and infotainment power rails |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed consumer and industrial equipment |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, preserving margin for downstream IC absolute maximum ratings |
Applications
| Automotive Power Rail 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 |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package; 8.0 V VWM, 12.0 V VC @ 32.3 A; 600 W PPPM | Surface-mount format requires PCB redesign; higher power rating suits higher-energy surges | Select SMBJ8.0A when board space is constrained and SMT assembly is preferred over through-hole DO-41. |
| 1.5KE8.2A | Same DO-41 package; identical VBR/VWM/VC; 1500 W PPPM (10/1000 µs), 1.5 kW rating | Higher pulse power supports longer-duration transients but larger thermal mass increases mounting constraints | Choose 1.5KE8.2A where legacy designs require higher surge margin without changing footprint or polarity marking. |
Compared with P4KE8.2A-E3/54, SMBJ8.0A offers SMT compatibility and higher power but demands layout change, while 1.5KE8.2A retains identical form factor and electrical thresholds but delivers 3.75× higher pulse energy-making it suitable for harsher surge environments where thermal management permits.

FAQ
What is the breakdown voltage range of the P4KE8.2A-E3/54?
The P4KE8.2A-E3/54 has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at a test current of 10 mA, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage protection design for 5 V and 8 V systems. The P4KE8.2A-E3/54's VBR is validated at 25 °C and exhibits a temperature coefficient of +0.060 %/°C.
Is the P4KE8.2A-E3/54 suitable for automotive applications?
Yes, the P4KE8.2A-E3/54 is AEC-Q101 qualified when ordered with the HE3 suffix (e.g., P4KE8.2AHE3/54). The standard P4KE8.2A-E3/54 carries the E3 suffix indicating RoHS compliance and JESD 201 Class 1A whisker resistance, but AEC-Q101 validation applies only to the HE3 variant. For automotive use, specify P4KE8.2AHE3/54 to ensure qualification for under-hood temperature cycling, humidity resistance, and mechanical shock testing per the AEC standard. The P4KE8.2A-E3/54 itself is not AEC-Q101 certified.
What is the maximum clamping voltage of the P4KE8.2A-E3/54 during a surge event?
The P4KE8.2A-E3/54 has a maximum clamping voltage (VC) of 12.1 V at its rated peak pulse current (IPPM) of 33.1 A, tested with a 10/1000 µs waveform. This value represents the highest voltage imposed on the protected circuit during worst-case transient conditions and is critical for ensuring downstream ICs remain within their absolute maximum voltage ratings. The P4KE8.2A-E3/54 maintains this clamping performance across its operational junction temperature range of –55 °C to +175 °C.
How does the P4KE8.2A-E3/54 differ from the 1.5KE8.2A in terms of surge handling?
The P4KE8.2A-E3/54 is rated for 400 W peak pulse power (10/1000 µs), whereas the 1.5KE8.2A is rated for 1500 W under identical waveform conditions-a 3.75× higher energy capacity. Both share identical VBR, VWM, and VC specifications and use the same DO-41 package, but the 1.5KE8.2A achieves higher power via larger silicon die and optimized thermal path. The P4KE8.2A-E3/54 is optimized for cost-sensitive, moderate-surge applications, while the 1.5KE8.2A suits high-energy environments like AC mains inputs or telecom line cards where longer-duration transients occur.
What is the reverse leakage current specification for the P4KE8.2A-E3/54 at its stand-off voltage?
The P4KE8.2A-E3/54 specifies a maximum reverse leakage current (ID) of 200 µA at its stand-off voltage (VWM) of 7.02 V, measured at 25 °C. This low leakage ensures minimal power loss in always-on circuits and avoids loading high-impedance nodes such as sensor outputs or reference voltage dividers. Leakage remains within specification across the full operating temperature range (–55 °C to +175 °C), supporting stable performance in wide-temperature applications. The P4KE8.2A-E3/54's leakage is verified per JEDEC test methods and documented in Vishay's official datasheet revision 16-Sep-2021.
