Product details
Overview
P6KE24CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 24 V breakdown voltage (VBR min/max = 22.8 V / 25.2 V), 33.2 V maximum clamping voltage at 18.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P6KE24CAHE3/54 datasheet, P6KE24CAHE3/54 pinout, P6KE24CAHE3/54 application, or P6KE24CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification for automotive use, DO-15 mechanical compatibility, and verified clamping performance under 10/1000 μs surge conditions.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC signal lines and differential buses without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at 20.5 V stand-off voltage), while the 20 °C/W junction-to-lead thermal resistance supports reliable power dissipation during transient events.
The device complies with AEC-Q101 stress testing for automotive applications and meets UL 94 V-0 flammability requirements. Its 175 °C maximum junction temperature and 100 A IFSM surge rating (unidirectional reference only; not applicable to bidirectional P6KE24CA) reflect robust transient handling - though for P6KE24CA, forward conduction is not defined per datasheet Notes (3) and polarity section.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V - Ensures reliable triggering above 20.5 V stand-off; tight 10.5 % tolerance enables precise overvoltage threshold setting |
| VC @ IPPM | 33.2 V - Clamps transients to safe levels for 3.3 V or 5 V logic interfaces when subjected to 18.1 A surge |
| IPPM | 18.1 A - Peak surge current handling with 10/1000 μs waveform; sufficient for IEC 61000-4-5 Level 3 (1 kV/2 Ω) |
| PPPM | 600 W - Sustains high-energy transients without degradation; derates linearly above 25 °C ambient |
| VWM | 20.5 V - Maximum continuous reverse working voltage; provides 17 % margin below VBR min for noise immunity |
| TJ max | 175 °C - Enables operation in under-hood automotive environments and industrial enclosures with elevated ambient temps |
| Package | DO-15 (DO-204AC) - Industry-standard axial leaded package; compatible with legacy through-hole assembly and manual repair |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; no polarity marking on bidirectional devices - terminals are symmetrical and interchangeable. Lead length ≥25.4 mm, body diameter 3.3–3.5 mm, total length ≥6.15 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge path | No designated anode or cathode; either terminal serves as input/output for transient energy diversion in AC or differential lines |
| Lead 1 / Lead 2 | Thermal and electrical interface | Both leads conduct surge current equally; junction-to-lead thermal resistance (20 °C/W) requires minimum 9.5 mm lead length for rated power dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA package; lower 600 W rating but tighter VC = 38.9 V @ 15.4 A; higher capacitance (~250 pF) | Suitable for PCB space-constrained designs; less optimal for high-frequency signal lines due to higher junction capacitance | Select SMBJ24CA when surface-mount assembly is required and board real estate is limited; verify layout clearance for thermal relief. |
| 1.5KE24CA | Higher 1500 W peak power; larger DO-201AD package; VC = 36.0 V @ 41.7 A; same VBR range | Better suited for high-energy industrial surge environments where 600 W is marginal; requires larger footprint and higher mounting torque | Choose 1.5KE24CA for mission-critical infrastructure where single-event energy exceeds 600 W; confirm mechanical retention in vibration-prone enclosures. |
Compared with SMBJ24CA and 1.5KE24CA, P6KE24CAHE3/54 offers the optimal balance of proven AEC-Q101 qualification, DO-15 through-hole compatibility, and validated 600 W clamping performance - making it ideal for automotive Tier-2 suppliers and industrial OEMs requiring traceable, legacy-compatible surge protection.

FAQ
What does the "CA" suffix indicate in P6KE24CAHE3/54?
The "CA" suffix in P6KE24CAHE3/54 denotes a bidirectional configuration, meaning the device clamps voltage transients equally in both polarities - unlike unidirectional "A" variants that conduct only in reverse bias. This makes P6KE24CAHE3/54 ideal for AC-coupled or differential signal protection where polarity is undefined or alternating.
Is P6KE24CAHE3/54 suitable for automotive applications?
Yes, P6KE24CAHE3/54 is AEC-Q101 qualified (per datasheet Note 1 and Mechanical Data section), confirming its suitability for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. The HE3 suffix specifically indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
What is the maximum clamping voltage of P6KE24CAHE3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE24CAHE3/54 is 33.2 V at 18.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across temperature and ensures downstream 3.3 V or 5 V ICs remain within absolute maximum ratings during transient events.
How does P6KE24CAHE3/54 differ from unidirectional P6KE24AHE3/54?
P6KE24CAHE3/54 is bidirectional with symmetrical clamping in both directions and no polarity marking, whereas P6KE24AHE3/54 is unidirectional with a cathode band and conducts only in reverse bias. The forward voltage (VF) specification does not apply to P6KE24CAHE3/54, and its leakage is specified at VWM in both directions.
What packaging format is used for P6KE24CAHE3/54?
P6KE24CAHE3/54 is supplied in 13" diameter paper tape and reel format with a base quantity of 4000 units per reel (per Ordering Information table). The "54" in the part number refers to the preferred package code indicating this reel configuration, and the "HE3" suffix confirms AEC-Q101 qualification and RoHS compliance.
