Product details
Overview
P4KE7.5CA-E3/54 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 7.13 V to 7.88 V breakdown voltage (VBR) at 10 mA test current, 6.40 V maximum stand-off voltage (VWM), and clamps up to 11.3 V at 35.4 A peak pulse current (IPPM) under 10/1000 µs waveform - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE7.5CA-E3/54 datasheet, P4KE7.5CA-E3/54 pinout, P4KE7.5CA-E3/54 application, or P4KE7.5CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, 400 W peak pulse power rating, low clamping ratio (VC/VBR ≈ 1.44), AEC-Q101 qualification, and DO-41 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche breakdown in both polarities, enabling robust transient suppression on AC-coupled or floating lines without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<500 µA at VWM), while the 10/1000 µs waveform rating reflects real-world lightning and inductive-switching surge immunity.
The P4KE7.5CA-E3/54 delivers 400 W peak pulse power dissipation with 0.01% duty cycle, supported by thermal resistance of 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient). It maintains operation across –55 °C to +175 °C junction temperature range and meets JESD 201 Class 1A whisker resistance per E3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Use Value: Eliminates need for external series impedance or RC filtering, reducing BOM count and board space in DIN-rail mounted controllers. |
| Consumer Audio Interface Protection | Telecom Line Card Surge Suppression |
Use Scenario: Safeguarding line-in/out jacks on AV receivers and soundbars against ESD and cable discharge events. IC Role / Device Role / Timing Role: Bidirectional TVS placed across unbalanced analog audio paths (e.g., RCA, 3.5 mm), conducting symmetrically on ± transient peaks. Use Value: Maintains low capacitance (<100 pF typical) to avoid high-frequency attenuation while suppressing >8 kV HBM ESD per IEC 61000-4-2. | Use Scenario: Front-end protection on telephone line interface cards exposed to lightning-induced surges on PSTN or VoIP trunk lines. IC Role / Device Role / Timing Role: Primary clamping device on tip/ring pair, coordinated with gas discharge tube (GDT) for staged surge handling. Use Value: Limits let-through voltage to telecom PHY ICs during 10/1000 µs surges up to 400 W, meeting GR-1089-CORE Level 3 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | Surface-mount SMB package; 7.0 V VWM, 7.78 V VBR min, 12.0 V VC @ 32.5 A; 600 W PPPM | Higher power rating but SMT-only; unsuitable for through-hole legacy designs | Select when board space is constrained and reflow assembly is available |
| 1.5KE7.5CA | Same DO-41 package; higher 1500 W PPPM; 7.13 V VBR min; 12.0 V VC @ 125 A; larger junction area | Over-specified for 400 W needs; higher cost and thermal mass | Choose only if system-level testing requires margin beyond 400 W surge compliance |
Compared with SMBJ7.0CA and 1.5KE7.5CA, the P4KE7.5CA-E3/54 provides optimal balance of proven DO-41 mechanical fit, AEC-Q101 qualification, and precise 400 W surge handling - making it ideal for cost-sensitive, high-reliability through-hole designs where footprint and qualification alignment outweigh raw power headroom.

FAQ
What is the breakdown voltage range of the P4KE7.5CA-E3/54?
The P4KE7.5CA-E3/54 has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured in both directions due to its bidirectional construction. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable design margins for 5 V and 6 V systems.
Is the P4KE7.5CA-E3/54 suitable for automotive applications?
Yes, the P4KE7.5CA-E3/54 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C junction temperature. Its glass-passivated junction, DO-41 mechanical robustness, and 400 W surge capability make it appropriate for under-hood and chassis-mounted automotive subsystems including sensor interfaces and body control modules.
How does the P4KE7.5CA-E3/54 differ from unidirectional P4KE7.5A variants?
The P4KE7.5CA-E3/54 is bidirectional with symmetrical clamping in both polarities and no polarity marking, whereas the unidirectional P4KE7.5A has a cathode band and conducts only in reverse bias. The CA version supports AC-coupled or floating lines; the A version requires correct orientation and is used where polarity is fixed and forward conduction must be blocked.
What is the maximum clamping voltage of the P4KE7.5CA-E3/54 during a surge event?
The P4KE7.5CA-E3/54 clamps to a maximum of 11.3 V at its rated peak pulse current of 35.4 A (10/1000 µs waveform). This clamping voltage is verified per Fig. 1 and Table 1 in Vishay Document 88365 and defines the upper voltage limit imposed on protected circuitry during transient events.
Does the P4KE7.5CA-E3/54 require heatsinking in typical applications?
No, the P4KE7.5CA-E3/54 is designed for transient-only operation and does not require heatsinking under normal conditions. Its 1.5 W steady-state power dissipation (PD) and 66 °C/W junction-to-lead thermal resistance are sufficient for brief surge events; continuous power dissipation must remain well below 1.5 W to avoid thermal runaway.
