Product details

Overview

5KP100HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, rated for 100 V stand-off voltage (V_WM), 111–123 V breakdown voltage (V_BR), and 5000 W peak pulse power (10/1000 µs). It clamps transients to ≤162 V at 30.9 A peak pulse current and is AEC-Q101 qualified for automotive electronics protection.

For engineers reviewing the 5KP100HE3/73 datasheet, 5KP100HE3/73 pinout, 5KP100HE3/73 application, or 5KP100HE3/73 equivalent, this page delivers verified electrical specs, clamping behavior, thermal derating curves, RoHS-compliant AEC-Q101 qualification status, and direct alternatives for overvoltage protection in DC power rails and signal lines.

Technical Context

The 5KP100HE3/73 uses a glass-passivated P600 chip junction optimized for high-energy transient suppression. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.

It operates across –55 °C to +175 °C junction temperature range with 0.110 %/°C V_BR temperature coefficient and exhibits low incremental surge resistance for stable clamping under repetitive 10/1000 µs surges at 0.01 % duty cycle.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	100 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin.
V_BR @ I_T = 5.0 mA	111–123 V - Breakdown voltage range at test current; ensures reliable turn-on during overvoltage events.
V_C @ I_PPM = 30.9 A	≤162 V - Clamped voltage under 5000 W transient; protects downstream ICs rated ≤162 V absolute max.
P_PPM	5000 W - Peak pulse power handling (10/1000 µs); sustains high-energy lightning or inductive switch-off surges.
T_J max.	+175 °C - Maximum junction temperature; supports operation in under-hood automotive environments.
Qualification	AEC-Q101 - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD.

Pinout & Package

Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; cathode denoted by color band. Lead finish complies with J-STD-002 and JESD 22-B102 solderability standards.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward conduction path	Connected to lower-potential side of protected circuit (e.g., ground or return line).
Cathode	Clamping node / high-side connection	Connected to higher-potential rail (e.g., +12 V, +24 V, or signal line); color band identifies this terminal.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ100AHE3/52	Lower peak power (600 W), SMC package, same V_WM = 100 V, V_C = 165 V @ 3.5 A	Not suitable for ISO 7637-2 load dump; limited to board-level ESD and low-energy transients.	Select when space-constrained layouts require SMC footprint and surge energy is ≤600 W.
1.5KE100A	Same V_WM = 100 V but lower P_PPM = 1500 W, DO-201 package, V_C = 166 V @ 9.1 A	Lacks AEC-Q101 qualification; not recommended for automotive production.	Use only in cost-sensitive industrial controls where AEC-Q101 is not mandated and surge energy is moderate.

Compared with SMBJ100AHE3/52 and 1.5KE100A, the 5KP100HE3/73 delivers 3.3× and 3.3× higher peak pulse power respectively, retains AEC-Q101 validation, and maintains tighter clamping (162 V vs. 165–166 V), making it the sole choice for automotive load dump and high-energy industrial surge protection.

FAQ

What is the clamping voltage of the 5KP100HE3/73 under maximum rated surge current?

The 5KP100HE3/73 clamps to a maximum of 162 V when subjected to its rated peak pulse current of 30.9 A (10/1000 µs waveform). This value is guaranteed per Vishay's datasheet Document Number 88308 and reflects worst-case V_C across production lot variation and temperature extremes up to +175 °C junction temperature.

Is the 5KP100HE3/73 suitable for automotive applications?

Yes, the 5KP100HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its HE3 suffix denotes compliance with JESD 201 Class 2 whisker testing and full AEC-Q101 stress qualification-including temperature cycling, high-temperature reverse bias, and ESD-making it appropriate for engine control units, body modules, and ADAS power supplies.

What does the "HE3" suffix mean in 5KP100HE3/73?

The "HE3" suffix in 5KP100HE3/73 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions and confirms enhanced reliability for automotive and industrial deployments where long-term solder joint integrity is critical.

How does the 5KP100HE3/73 differ from the 5KP100A?

The 5KP100HE3/73 is the AEC-Q101 qualified, RoHS-compliant version of the 5KP100A. While both share identical electrical specs (V_WM = 100 V, V_BR = 111–123 V, V_C ≤ 162 V), only the HE3 variant undergoes automotive-grade reliability testing and meets JESD 201 Class 2 whisker requirements-essential for production automotive designs.

Can the 5KP100HE3/73 be used in bidirectional configurations?

No, the 5KP100HE3/73 is unidirectional only. Its internal structure supports clamping only in reverse-bias mode; forward conduction occurs above ~3.5 V. For bidirectional protection, two 5KP100HE3/73 devices must be connected in series opposition-or a dedicated bidirectional TVS such as SMAJ100A should be selected instead.
