Product details
Overview
P4KE200AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features 200 V breakdown voltage (VBR min/max = 190–210 V), 171 V stand-off voltage (VWM), 274 V clamping voltage (VC) at 1.5 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the P4KE200AHE3/54 datasheet, P4KE200AHE3/54 pinout, P4KE200AHE3/54 application, or P4KE200AHE3/54 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, unidirectional polarity with cathode band marking, DO-41 mechanical compatibility, thermal resistance (RθJL = 66 °C/W), and compliance with JESD 201 Class 2 whisker testing.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, conducting only when reverse voltage exceeds its breakdown threshold (190–210 V). Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for limiting transient energy delivered to downstream ICs or MOSFETs.
Designed for single-pulse suppression, it supports repetitive operation at ≤0.01% duty cycle and derates linearly above 25 °C ambient per Fig. 2. The device sustains 40 A non-repetitive forward surge (8.3 ms half-sine) and exhibits 0.108 %/°C temperature coefficient of VBR, ensuring stable clamping across -55 to +175 °C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 190 V / 210 V - defines precise clamping initiation window; ensures reliable turn-on before system damage |
| VWM | 171 V - maximum continuous reverse operating voltage; must exceed normal circuit rail by ≥10% |
| VC @ IPPM | 274 V - clamped voltage during 1.5 A 10/1000 µs surge; determines peak stress on protected device |
| PPPM | 400 W - peak pulse power handling; defines transient energy absorption capability per pulse |
| IFSM | 40 A - 8.3 ms half-sine forward surge rating; validates robustness against inrush or fault currents |
| TJ max | +175 °C - maximum junction temperature; enables high-temperature automotive under-hood deployment |
| RθJL | 66 °C/W - junction-to-lead thermal resistance; informs heatsinking requirements for sustained power dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | DO-214AA package; 200 V VBR; 300 W PPPM; RθJA = 40 °C/W | Higher power density but lower surge rating; requires PCB copper area for thermal management | Select SMBJ200A when board space is constrained and thermal vias are available; P4KE200AHE3/54 preferred for through-hole legacy designs and higher surge margin. |
| 1.5KE200A | DO-201AD package; same VBR/VC; 1500 W PPPM; 100 A IPPM | Higher surge capacity but larger footprint and higher cost; intended for primary-level protection | Choose 1.5KE200A for front-end AC/DC input stages; P4KE200AHE3/54 is optimized for secondary-side point-of-load protection with tighter layout constraints. |
Compared with SMBJ200A and 1.5KE200A, the P4KE200AHE3/54 delivers balanced surge capability (400 W), proven AEC-Q101 reliability, and DO-41 through-hole compatibility-making it ideal for cost-sensitive, high-volume automotive and industrial control boards where manual assembly or wave soldering is used.

FAQ
What is the breakdown voltage tolerance for P4KE200AHE3/54?
The P4KE200AHE3/54 has a specified breakdown voltage range of 190 V to 210 V at 1.0 mA test current, representing a ±5% tolerance around the nominal 200 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable system-level surge margin calculations without derating overhead.
Is P4KE200AHE3/54 suitable for bidirectional transient protection?
No, P4KE200AHE3/54 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the P4KE200CA variant. Using P4KE200AHE3/54 in AC-coupled or symmetrical surge scenarios would result in forward conduction during negative half-cycles, potentially causing failure or incorrect clamping.
What does the "HE3/54" suffix indicate in P4KE200AHE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies packaging in 13-inch paper tape and reel with 5500 units per reel. This distinguishes it from commercial-grade "E3" variants and confirms suitability for automotive and high-reliability industrial deployments.
How does thermal resistance affect P4KE200AHE3/54 performance in high-temperature environments?
P4KE200AHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W. In high-temperature PCB layouts, this value directly impacts steady-state power dissipation limits: at 75 °C lead temperature, its rated power drops to 1.5 W. Proper lead length (≥9.5 mm) and copper pour design are essential to maintain safe junction temperatures below 175 °C during repeated surge events.
Can P4KE200AHE3/54 replace older P4KE200A parts in existing designs?
Yes, P4KE200AHE3/54 is a direct drop-in replacement for legacy P4KE200A parts, maintaining identical electrical characteristics, DO-41 mechanical dimensions, and pinout. The HE3 suffix adds AEC-Q101 qualification and enhanced whisker resistance, making it suitable for new designs targeting automotive or extended-lifecycle industrial applications without layout or schematic changes.
