Product details

Overview

5KP6.0A-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC power rails and signal lines. It features 5000 W peak pulse power (10/1000 μs), 6.0 V stand-off voltage (V_WM), 6.67–7.37 V breakdown voltage (V_BR at 50 mA), and clamps to ≤10.3 V at 485 A peak pulse current - used in automotive power supply output protection and industrial sensor interface circuits.

For engineers reviewing the 5KP6.0A-E3/73 datasheet, 5KP6.0A-E3/73 pinout, 5KP6.0A-E3/73 application, or 5KP6.0A-E3/73 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, clamping performance under 10/1000 μs transients, and RoHS-compliant packaging details per Vishay Document 88308 Rev. 20-Nov-12.

Technical Context

This TVS diode operates as a voltage-clamping overvoltage protection device with a glass-passivated P600 junction. Its unidirectional polarity enables use in DC-biased circuits where reverse conduction must be blocked until breakdown threshold is exceeded. The 5000 W peak pulse rating is defined for non-repetitive 10/1000 μs waveforms at ≤0.01% duty cycle, with thermal derating above 25 °C ambient per Figure 2.

Clamping occurs within <1 ps response time, limiting transient-induced voltage overshoot across protected ICs or MOSFETs. The device exhibits low incremental surge resistance and maintains stable V_BR temperature coefficient of +0.061 %/°C, ensuring predictable turn-on behavior across -55 °C to +175 °C operating junction range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	6.0 V - maximum continuous reverse operating voltage before leakage exceeds 5000 μA; sets upper limit for safe DC bias in protected circuit.
V_BR @ I_T=50 mA	6.67–7.37 V - measured breakdown range confirming tight 10% tolerance; ensures reliable triggering margin above V_WM.
V_C @ I_PPM=485 A	≤10.3 V - clamping voltage during full-rated 5000 W transient; defines worst-case overvoltage seen by downstream components.
I_PPM	485 A - peak pulse current capability with 10/1000 μs waveform; determines survivability against lightning or EFT events.
P_PPM	5000 W - peak pulse power dissipation capacity; validates suitability for high-energy surges in automotive and industrial systems.
T_J max.	+175 °C - maximum junction temperature; supports operation in under-hood automotive environments and high-power supply designs.
AEC-Q101	Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A108.

Pinout & Package

Package: P600 molded epoxy case with matte tin-plated leads; cathode denoted by color band; UL 94 V-0 rated; RoHS compliant (E3 suffix); 2.776 g unit weight; lead-free and whisker-tested per JESD 201 Class 1A.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward conduction terminal	Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration; conducts during forward surge.
Cathode	Reverse-biased clamping terminal	Connected to protected line (e.g., +12 V rail); avalanche breakdown initiates here when V_WM is exceeded, shunting surge to anode.

Key Features

Feature	Design Value
5000 W peak pulse power	Enables protection against severe ISO 7637-2 Pulse 5a/b and IEC 61000-4-5 Level 4 surges without cascading failure.
Fast response time (<1 ps)	Prevents voltage overshoot from reaching sensitive downstream logic or analog circuitry before clamping activates.
AEC-Q101 qualification	Validates long-term reliability in automotive applications including engine control units, body electronics, and ADAS power domains.
Low clamping ratio (V_C/V_BR ≈ 1.44)	Minimizes stress on protected devices by maintaining tight voltage margin between breakdown and clamping thresholds.
P600 package thermal robustness	Supports 8.0 W steady-state power dissipation on infinite heatsink at T_L = 75 °C, enabling integration into compact PCB layouts with minimal copper area.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ6.0A	Lower peak power (600 W), smaller SMB package, same V_WM/V_BR range, higher V_C/I_PPM ratio (11.2 V @ 53.3 A).	Suitable for low-energy ESD and EFT protection on data lines; insufficient for load dump or lightning-level surges.	Select SMBJ6.0A only when space-constrained layouts and sub-1 kW surge levels are confirmed.
1.5KE6.8A	Same P600 package, 1500 W peak power, tighter V_BR tolerance (6.8–7.5 V), higher V_C (11.5 V @ 130 A), no AEC-Q101 qualification.	Acceptable for industrial power rails but not automotive qualified; requires additional validation for automotive temperature cycling.	Choose 1.5KE6.8A if AEC-Q101 is not required and 5000 W rating is excessive for the application's surge profile.

Compared with SMBJ6.0A and 1.5KE6.8A, the 5KP6.0A-E3/73 uniquely combines AEC-Q101 qualification, 5000 W surge handling, and P600 thermal robustness - making it the only option among the three validated for automotive load dump and industrial 4 kV surge immunity without derating or parallel staging.

FAQ

What is the maximum clamping voltage of the 5KP6.0A-E3/73 under full-rated surge conditions?

The 5KP6.0A-E3/73 clamps to a maximum of 10.3 V when subjected to its rated 485 A peak pulse current (10/1000 μs waveform). This value is guaranteed per Vishay Document 88308 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The 5KP6.0A-E3/73 achieves this with low incremental surge resistance, ensuring consistent clamping performance across production lots.

Is the 5KP6.0A-E3/73 suitable for bidirectional transient protection?

No, the 5KP6.0A-E3/73 is unidirectional only, with a cathode band marking and specified breakdown only in reverse bias. It blocks forward current up to 100 A (V_F = 3.5 V) but does not provide symmetrical clamping for AC or bipolar transients. For bidirectional protection, a paired device or dedicated bidirectional TVS such as 5KP6.0CA must be selected instead of the 5KP6.0A-E3/73.

Does the 5KP6.0A-E3/73 require a heatsink for continuous operation?

The 5KP6.0A-E3/73 is rated for 8.0 W power dissipation only when mounted on an infinite heatsink at lead temperature (T_L) = 75 °C - a condition not achievable in typical PCB layouts. Under normal operation, it handles only non-repetitive surges; steady-state power dissipation is negligible. Therefore, no heatsink is required for its intended transient suppression function, though adequate copper pour improves thermal response during repeated low-duty-cycle events.

What does the "E3/73" suffix indicate in 5KP6.0A-E3/73?

The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "73" specifies the preferred packaging code - 73 indicates 800-piece quantity in 13-inch paper tape and reel. This differs from "/54", which denotes alternate reel packaging. The 5KP6.0A-E3/73 is not AEC-Q101 qualified; for automotive grade, the HE3 variant (e.g., 5KP6.0AHE3/73) must be used instead of the 5KP6.0A-E3/73.

How does the 5KP6.0A-E3/73 compare to standard Zener diodes in surge protection?

Unlike general-purpose Zener diodes, the 5KP6.0A-E3/73 is optimized for high-current transient suppression: it features a glass-passivated P600 junction capable of 485 A single-pulse current, 5000 W peak power, and sub-nanosecond response. Standard Zeners lack surge-rated construction and would fail catastrophically under identical conditions. The 5KP6.0A-E3/73 also offers guaranteed clamping voltage and AEC-Q101 qualification - attributes absent in basic Zener diodes.
