Product details

Overview

5KP90A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on power rails and signal lines. It features 5000 W peak pulse power (10/1000 μs), 90 V stand-off voltage (V_WM), 100–111 V breakdown voltage (V_BR), 146 V maximum clamping voltage (V_C) at 34.2 A, and AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the 5KP90A-E3/54 datasheet, 5KP90A-E3/54 pinout, 5KP90A-E3/54 application, or 5KP90A-E3/54 equivalent, key selection criteria include clamping performance under 10/1000 μs surges, thermal derating above 25 °C, unidirectional polarity configuration, and compatibility with 13" tape-and-reel automated assembly.

Technical Context

The 5KP90A-E3/54 employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective clamping of lightning-induced transients and inductive switching spikes. Its unidirectional structure provides reverse-biased surge suppression while allowing forward conduction only during fault conditions.

Rated for 5000 W peak pulse power and 500 A non-repetitive forward surge current (8.3 ms half-sine), it operates across –55 °C to +175 °C junction temperature range and supports soldering per JESD 22-B106 (275 °C, 10 s). The device is RoHS-compliant (E3 suffix) and meets JESD 201 Class 1A whisker test requirements.

Cathode	Surge input / protected line connection	Marked by color band; connected to line being protected (e.g., 12 V battery rail); blocks normal operation, avalanches during overvoltage.

Key Features

Feature	Design Value
5000 W peak pulse power (10/1000 μs)	Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV) surges on 12 V/24 V systems.
AEC-Q101 qualified	Validated for automotive powertrain and body electronics applications requiring zero defect reliability over temperature and lifetime.
Low clamping ratio (V_C/V_WM = 1.62)	Minimizes overvoltage exposure to downstream MOSFETs, controllers, and sensors during transient events.
P600 glass-passivated junction	Provides stable V_BR tolerance (±10 %), low leakage (<2 μA at V_WM), and robust surge endurance.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Littelfuse SMAJ90A	Lower peak power (400 W), SMA package (surface-mount), 90 V V_WM, 146 V V_C at 27.4 A	Designed for PCB space-constrained consumer electronics; lacks AEC-Q101 qualification and P600 thermal mass	Select when board area is limited and surge energy is ≤400 W; not suitable for automotive under-hood use.
ON Semiconductor 1.5KE91A	Same P600 package, 91 V V_WM, but lower PPPM (1500 W), higher V_C (150 V at 10 A), no AEC-Q101	Targeted at cost-sensitive industrial controls where full 5 kW rating is unnecessary	Choose for legacy designs requiring drop-in replacement with reduced surge margin; verify thermal design for repeated events.

Compared with SMAJ90A and 1.5KE91A, the 5KP90A-E3/54 delivers 3.3× higher surge power handling and automotive-grade qualification-critical for protecting high-reliability power rails where transient energy exceeds 1 kJ and ambient temperatures exceed 105 °C.

FAQ

What is the clamping voltage of the 5KP90A-E3/54 under a 10/1000 μs surge?

The 5KP90A-E3/54 has a maximum clamping voltage (V_C) of 146 V at 34.2 A peak pulse current (I_PPM) under the standardized 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures downstream components see no more than 146 V during worst-case surge events, directly supporting design margin calculations for 16 V-rated input stages.

Is the 5KP90A-E3/54 suitable for automotive applications?

Yes, the 5KP90A-E3/54 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C junction temperature, making it suitable for under-hood and powertrain applications. Its P600 package provides mechanical robustness and thermal mass needed for sustained surge dissipation in automotive environments where ISO 7637-2 Pulse 5a load dump events occur.

What does the "E3/54" suffix indicate in 5KP90A-E3/54?

The "E3" suffix denotes RoHS-compliant, commercial-grade construction meeting JESD 201 Class 1A whisker test requirements; "/54" specifies the preferred packaging code for 13-inch diameter paper tape and reel, with a base quantity of 800 units per reel. This format ensures compatibility with standard SMT pick-and-place equipment and traceable lot control.

How does the 5KP90A-E3/54 differ from the 5KP90CA variant?

The 5KP90A-E3/54 is unidirectional, providing surge suppression only in reverse bias, while the 5KP90CA is bidirectional and suppresses surges of either polarity. The 5KP90A-E3/54 offers tighter V_BR tolerance (100–111 V) and lower leakage (<2 μA), making it optimal for DC power rail protection where polarity is fixed and leakage sensitivity matters.

Can the 5KP90A-E3/54 replace a 1.5KE91A in an existing design?

The 5KP90A-E3/54 is not a direct pin-compatible replacement for the 1.5KE91A due to higher power dissipation and different thermal profile, though both use P600 packages. While electrical parameters align closely (V_WM = 90 V vs. 91 V, V_C = 146 V vs. 150 V), the 5KP90A-E3/54's 5000 W rating requires verification of PCB copper area and heatsinking to avoid thermal runaway during repetitive surges.
