Product details
Overview
P4KE200A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 200 V breakdown voltage (VBR min/max = 190–210 V), 171 V stand-off voltage (VWM), 274 V clamping voltage at 1.5 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P4KE200A-E3/54 datasheet, P4KE200A-E3/54 pinout, P4KE200A-E3/54 application, or P4KE200A-E3/54 equivalent, key selection criteria include unidirectional polarity, DO-41 mechanical compatibility, 175 °C max junction temperature, AEC-Q101 qualification status (E3 suffix denotes commercial grade; HE3 required for automotive), and thermal resistance (RθJL = 66 °C/W).
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with DC power rails or parallel to sensitive inputs. Its glass-passivated junction enables fast response (<1 ns) to ESD and inductive switching transients, while low incremental surge resistance ensures stable clamping under repetitive 0.01% duty cycle pulses.
The device complies with JEDEC JESD22-B106 (solder dip) and JESD201 Class 1A whisker testing. With VF = 5.0 V at 25 A forward surge and IFSM = 40 A (8.3 ms half-sine), it supports robust overvoltage handling in unidirectional configurations only - bidirectional variants use "CA" suffix (e.g., P4KE200CA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190 V / 210 V - defines guaranteed breakdown threshold at 1.0 mA test current; sets minimum clamping onset point |
| VWM | 171 V - maximum continuous reverse working voltage; must exceed normal circuit operating voltage |
| VC @ IPPM | 274 V - clamped voltage at 1.5 A peak pulse current; determines protected circuit's maximum transient exposure |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform; defines single-event surge energy capacity |
| TJ max | +175 °C - maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial environments |
| RθJL | 66 °C/W - thermal resistance junction-to-lead; informs heatsinking requirements when mounted on PCB copper pour |
Pinout & Package

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load dump (ISO 16750-2) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges above 171 V before reaching downstream regulators and microcontrollers. Use Value: Limits transient voltage to ≤274 V at 1.5 A, preventing latch-up or gate oxide damage in 3.3 V/5 V logic ICs powered from buck converters. | Use Scenario: Analog output lines (4–20 mA, 0–10 V) from pressure/temperature sensors in factory automation cabinets. IC Role / Device Role / Timing Role: TVS installed across sensor output and system ground to suppress coupling from nearby motor drives and relay coils. Use Value: Clamps fast-rising transients (<100 ns) without adding capacitance that would distort low-bandwidth analog signals. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Input Stage |
Use Scenario: DC input ports of base station remote radio units fed via PoE or centralized DC distribution. IC Role / Device Role / Timing Role: Primary-level TVS on 48 V input bus, upstream of DC/DC converters and hot-swap controllers. Use Value: Absorbs 400 W surges per IEC 61000-4-5 while maintaining VWM margin above nominal 48 V ±10%, avoiding false triggering. | Use Scenario: Secondary-side DC output (12 V/19 V) of wall adapters powering laptops and monitors. IC Role / Device Role / Timing Role: Final-stage TVS on output connector to prevent user-induced ESD from damaging connected devices. Use Value: Provides 274 V clamping with 1.5 A peak current capability, compatible with standard USB-C PD and legacy barrel jack form factors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | DO-214AA package (SMB), 200 V VBR, same 400 W PPPM, but lower RθJA (50 °C/W vs. 100 °C/W) | Surface-mount footprint; requires reflow-compatible layout; better thermal performance on dense PCBs | Select SMBJ200A when board space is constrained and automated assembly is preferred over through-hole mounting. |
| 1.5KE200A | Same DO-41 package, 200 V VBR, but 1500 W PPPM (10/1000 μs), higher IPPM (7.2 A), larger junction area | Higher energy absorption for infrequent but severe surges (e.g., lightning-induced); larger physical size and higher cost | Choose 1.5KE200A where IEC 61000-4-5 Level 5 (6 kV) compliance is mandated and PCB real estate allows larger axial device. |
Compared with SMBJ200A and 1.5KE200A, P4KE200A-E3/54 offers optimal balance of axial-mount reliability, AEC-Q101-ready qualification path (via HE3), and cost-effective 400 W surge handling for mid-tier industrial and automotive subsystems - without requiring SMT rework or oversized packaging.

FAQ
What is the polarity configuration of P4KE200A-E3/54?
P4KE200A-E3/54 is a unidirectional TVS diode: its cathode is marked with a color band, and it conducts only when the cathode is at higher potential than the anode. This configuration provides asymmetric clamping - ideal for DC power lines where reverse voltage is not expected. Bidirectional operation requires the CA-suffixed variant (e.g., P4KE200CA), which has no polarity marking and clamps in both directions.
Does P4KE200A-E3/54 meet AEC-Q101 for automotive use?
No - the "E3" suffix indicates RoHS-compliant commercial grade. For AEC-Q101 qualification, the part must carry the "HE3" suffix (P4KE200A-HE3/54). Both share identical electrical specs and DO-41 packaging, but only HE3 undergoes the full stress test sequence per AEC-Q101 Rev D, including temperature cycling, HTRB, and ESD testing required for under-hood automotive modules.
What is the maximum clamping voltage of P4KE200A-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P4KE200A-E3/54 is 274 V, measured at 1.5 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value represents the upper limit of voltage seen by downstream circuitry during a defined surge event - critical for ensuring protected ICs remain within absolute maximum ratings.
Can P4KE200A-E3/54 be used in bidirectional AC signal lines?
No - P4KE200A-E3/54 is strictly unidirectional and will not clamp reverse-polarity transients. For AC or bipolar signal protection (e.g., RS-485, CAN bus), a bidirectional variant such as P4KE200CA must be used. Using P4KE200A-E3/54 on AC lines risks failure during negative half-cycles due to lack of reverse breakdown specification.
What is the thermal resistance and how does it affect PCB layout for P4KE200A-E3/54?
P4KE200A-E3/54 has RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm). To manage self-heating during repetitive surges, PCB layout should maximize copper area connected to both leads - especially the cathode - and avoid narrow traces. Thermal relief pads are discouraged; solid copper pours improve heat dissipation and extend surge endurance.
