Product details
Overview
P4KE62CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 62 V breakdown voltage (VBR min/max = 58.9 V / 65.1 V), 53.0 V stand-off voltage (VWM), 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE62CAHE3/54 datasheet, P4KE62CAHE3/54 pinout, P4KE62CAHE3/54 application, or P4KE62CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification for automotive use, DO-41 mechanical compatibility, low leakage (<1.0 μA at VWM), and thermal resistance (RθJL = 66 °C/W) for reliable surge handling in industrial sensor interfaces and power supply rails.
Technical Context
This device operates as a voltage-clamping protection element in bidirectional configurations, responding to transient overvoltages in either polarity without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1.0 ns), while the DO-41 package supports manual or automated through-hole assembly with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
The P4KE62CAHE3/54 delivers 400 W peak pulse power dissipation under 10/1000 μs waveform at TA = 25 °C, derating linearly above 25 °C per Fig. 2, and sustains 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C. Its temperature coefficient of VBR is +0.104 %/°C, enabling predictable voltage shift across its -55 °C to +175 °C operating junction range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Surface-mount SMB package; 64 V VBR; 600 W PPPM; higher IPPM (10.3 A) | Requires PCB redesign for SMT placement; better suited for space-constrained consumer electronics | Select when board area is limited and reflow compatibility is required; not drop-in for DO-41 footprint |
| 1.5KE62CA | Same DO-41 package; 62 V VBR; 1500 W PPPM; higher VC (101 V) | Higher clamping voltage reduces protection margin but handles larger single-event surges | Choose for infrequent high-energy threats (e.g., utility grid coupling) where 85 V clamping is insufficient |
Compared with SMBJ64CA and 1.5KE62CA, the P4KE62CAHE3/54 offers balanced 400 W surge handling in a proven through-hole package with AEC-Q101 qualification-making it optimal for cost-sensitive, high-reliability automotive and industrial designs requiring field-serviceable assembly and validated automotive stress performance.

FAQ
What is the meaning of the 'CA' and 'HE3' suffixes in P4KE62CAHE3/54?
The 'CA' suffix indicates a bidirectional configuration-meaning the P4KE62CAHE3/54 clamps voltage transients in both polarities without cathode marking. The 'HE3' suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, confirming suitability for automotive under-hood applications. This makes the P4KE62CAHE3/54 distinct from unidirectional variants like P4KE62A and non-automotive versions such as P4KE62CA-E3.
Does P4KE62CAHE3/54 have polarity markings on the package?
No, the P4KE62CAHE3/54 does not feature polarity markings because it is a bidirectional TVS diode. Unlike unidirectional types (e.g., P4KE62A) that use a color band to indicate the cathode end, the P4KE62CAHE3/54 has symmetric electrical behavior in both directions and therefore omits any marking. This simplifies orientation during manual or automated through-hole assembly of the DO-41 package.
What is the maximum clamping voltage of P4KE62CAHE3/54 and under what test condition is it specified?
The maximum clamping voltage (VC) of the P4KE62CAHE3/54 is 85.0 V, measured at a peak pulse current (IPPM) of 4.7 A using the standard 10/1000 μs double-exponential waveform. This value is guaranteed per Vishay Document Number 88365 and defines the upper voltage limit imposed on protected circuitry during surge events-critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the thermal resistance RθJL = 66 °C/W impact PCB layout for P4KE62CAHE3/54?
The P4KE62CAHE3/54's typical junction-to-lead thermal resistance of 66 °C/W means that each watt of sustained power dissipation raises the junction temperature by 66 °C above lead temperature. To maintain TJ ≤ 175 °C, PCBs should provide adequate copper land area around both leads-especially for applications with repetitive surges-and avoid excessive trace length or narrow traces that increase lead thermal impedance. This parameter directly informs heatsinking decisions for the P4KE62CAHE3/54 in high-duty-cycle scenarios.
Is P4KE62CAHE3/54 suitable for protecting RS-485 communication lines?
Yes, the P4KE62CAHE3/54 is suitable for RS-485 line protection due to its bidirectional clamping, fast response (<1 ns), and low leakage (<1.0 μA at 53 V). When placed across differential pairs or from line to ground, it suppresses ESD and lightning-induced transients while preserving signal integrity. Its DO-41 package allows easy integration into industrial interface modules, and AEC-Q101 qualification adds confidence for mission-critical deployments where the P4KE62CAHE3/54 may be used alongside other hardened components.
