Product details
Overview
P4KE100CHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in DO-41 package, rated for 100 V breakdown voltage (VBR = 95.0–105 V at IT = 1.0 mA), 400 W peak pulse power (10/1000 μs), and 137 V maximum clamping voltage (VC) at 2.9 A peak pulse current - designed to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial power supplies.
For engineers reviewing the P4KE100CHE3/54 datasheet, P4KE100CHE3/54 pinout, P4KE100CHE3/54 application, or P4KE100CHE3/54 equivalent, this AEC-Q101 qualified TVS diode offers verified clamping performance, RoHS-compliant matte tin leads, and DO-41 mechanical compatibility for board-level surge protection in DC power rails and low-speed data interfaces.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below its 85.5 V stand-off voltage (VWM) and rapidly avalanches above its 95–105 V breakdown threshold to limit transient energy. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1 ns) under ESD or lightning-induced surges.
Thermal design is constrained by RθJL = 66 °C/W and TJ(max) = 175 °C, with power derating beginning above 25 °C ambient. The device supports 40 A non-repetitive forward surge (8.3 ms half-sine) and exhibits +0.106 %/°C temperature coefficient of VBR, enabling predictable clamping across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V at 1.0 mA test current - defines precise avalanche initiation window for reliable overvoltage triggering |
| VWM | 85.5 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 137 V at 2.9 A - clamping voltage during 400 W transient, limiting downstream stress to safe levels |
| PPPM | 400 W (10/1000 μs waveform) - peak surge handling capacity for repetitive transients at 0.01% duty cycle |
| IFSM | 40 A (8.3 ms half-sine) - surge current rating for unidirectional forward conduction during power rail faults |
| TJ(max) | +175 °C - enables operation in under-hood automotive environments and high-temperature industrial enclosures |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads: cathode indicated by color band; matte tin-plated terminals compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance (HE3 suffix).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | DO-214AA package; 100 V VBR; 600 W PPPM; 1.6 pF typical capacitance | Higher surge rating but larger footprint; better suited for PCB space-constrained designs needing >400 W headroom | Select SMBJ100A when board layout allows SMC/SMB package and higher peak power margin is required. |
| 1.5KE100A | DO-201AD package; same VBR/VC; 1500 W PPPM; 100 A IPPM | Higher surge capacity but slower thermal response due to larger junction-to-lead resistance (RθJL = 1.1 °C/W) | Choose 1.5KE100A only for infrequent, high-energy events where DO-41 thermal limits are insufficient. |
Compared with SMBJ100A and 1.5KE100A, P4KE100CHE3/54 delivers optimal balance of AEC-Q101 qualification, DO-41 legacy compatibility, and 400 W surge handling - making it preferred for cost-sensitive, thermally constrained automotive and industrial control boards where proven reliability and standard through-hole assembly are critical.

FAQ
What is the breakdown voltage tolerance for P4KE100CHE3/54?
The P4KE100CHE3/54 has a specified breakdown voltage range of 95.0 V to 105 V at 1.0 mA test current, representing ±5% tolerance around the nominal 100 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports reliable overvoltage detection in safety-critical systems where precise trip thresholds are required.
Is P4KE100CHE3/54 suitable for bidirectional transient protection?
No, P4KE100CHE3/54 is a unidirectional TVS diode - it protects against positive transients only when oriented with cathode toward the protected rail. For bidirectional protection, Vishay offers the P4KE100CA variant (with CA suffix); the HE3/54 suffix on P4KE100CHE3/54 confirms unidirectional construction and AEC-Q101 qualification, not symmetrical clamping capability.
What does the "HE3/54" suffix indicate in P4KE100CHE3/54?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery (5500 units per reel). This distinguishes P4KE100CHE3/54 from commercial-grade P4KE100A-E3/54 and confirms automotive-grade reliability and packaging format.
How does P4KE100CHE3/54 perform under elevated ambient temperatures?
P4KE100CHE3/54 derates linearly above 25 °C ambient: its 400 W peak pulse power drops to ~200 W at 80 °C and ~100 W at 125 °C, per Figure 2 in the datasheet. Engineers must apply this derating when designing for under-hood automotive or enclosed industrial environments to maintain clamping integrity during repeated surge events.
Can P4KE100CHE3/54 replace P4KE100A in existing designs?
Yes - P4KE100CHE3/54 is a direct drop-in replacement for P4KE100A in terms of electrical specs, DO-41 package, and pinout; the added HE3 qualification provides enhanced reliability for automotive use without layout changes. However, its AEC-Q101 validation and Class 2 whisker resistance make it preferable for new designs targeting automotive or high-reliability industrial applications.
