Product details
Overview
5KP24A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on power rails and signal lines. It features 24.0 V stand-off voltage (VWM), 26.7–29.5 V breakdown voltage (VBR) at 5.0 mA, 5000 W peak pulse power (10/1000 μs), 129 A peak pulse current (IPPM), and clamps to ≤38.9 V at rated current - used in automotive power supply overvoltage protection and industrial sensor interface circuits.
For engineers reviewing the 5KP24A-E3/54 datasheet, 5KP24A-E3/54 pinout, 5KP24A-E3/54 application, or 5KP24A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, unidirectional polarity compatibility with DC-biased lines, P600 thermal dissipation capability, and AEC-Q101 qualification status for automotive deployment.
Technical Context
The 5KP24A-E3/54 employs a glass-passivated P600 junction optimized for fast response (<1 ns) to transients induced by inductive switching or lightning surges. Its low incremental surge resistance ensures stable clamping under repetitive 0.01% duty cycle pulses, while the unidirectional structure provides reverse-biased surge suppression without forward conduction during normal operation.
Designed for placement across DC power inputs or low-speed signal lines, it operates within -55 °C to +175 °C junction temperature range and withstands 500 A non-repetitive forward surge (8.3 ms half-sine). The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 24.0 V - maximum continuous reverse voltage before significant leakage; sets minimum operating margin above system nominal rail (e.g., 24 V systems). |
| VBR (Breakdown Voltage) | 26.7–29.5 V at 5.0 mA - guaranteed avalanche onset range; defines threshold where clamping initiates under transient stress. |
| VC (Clamping Voltage) | ≤38.9 V at 129 A (10/1000 μs) - maximum voltage seen by downstream circuit during full-rated surge; determines safe headroom for protected ICs. |
| PPPM (Peak Pulse Power) | 5000 W - energy-handling capacity for standardized 10/1000 μs waveform; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| IFSM (Surge Current) | 500 A (8.3 ms half-sine) - withstands high-current short-duration events like load dump in automotive 24 V systems. |
| TJ max. | +175 °C - allows operation in under-hood or industrial enclosures without derating below ambient 125 °C with proper heatsinking. |
| Polarity | Unidirectional - cathode-band marked; suitable only for DC-biased lines where reverse surge protection is required. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; 0.375" (9.5 mm) body length; lead spacing matches standard through-hole PCB footprints for high-power discrete mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side reference | Connected to system ground or lower-potential node; forms cathode-to-anode clamping path during reverse transients. |
| Cathode | Reverse surge input / high-side connection | Marked with color band; tied to protected line (e.g., 24 V rail); conducts avalanche current to anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications per stress test requirements including HTOL, TC, UHAST. |
| 5000 W peak pulse rating | Supports IEC 61000-4-5 combination wave testing up to 4 kV open-circuit / 2 kA short-circuit without failure. |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes voltage overshoot during surge, reducing risk of latch-up or damage to downstream 3.3 V/5 V logic interfaces. |
| Fast response time (<1 ns) | Engages before transient reaches peak amplitude, preventing propagation into sensitive analog or digital circuitry. |
| P600 thermal mass | Enables >8 W steady-state dissipation at TL = 75 °C with infinite heatsink; supports repeated surge events in industrial motor drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range | Limited to lower-energy surges (IEC 61000-4-2/4-4); unsuitable for load dump or high-current industrial transients | Select when board space is constrained and surge threat level is ≤1 kV/500 A. |
| 1.5KE24A | Same P600 package but lower PPPM (1500 W), higher clamping voltage (43.5 V), no AEC-Q101 qualification | Not validated for automotive use; insufficient clamping margin for 24 V systems with tight VDD tolerances | Choose only for cost-sensitive commercial designs where AEC-Q101 and 5 kW rating are not required. |

FAQ
What is the clamping voltage of the 5KP24A-E3/54 under full-rated surge conditions?
The 5KP24A-E3/54 clamps to a maximum of 38.9 V when subjected to its rated 129 A peak pulse current (10/1000 μs waveform). This value is measured and guaranteed per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The 5KP24A-E3/54 maintains this clamping performance across its specified operating temperature range.
Is the 5KP24A-E3/54 suitable for automotive applications?
Yes, the 5KP24A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, robust P600 package, and validated performance under load dump (ISO 7637-2 Pulse 5a) and ESD stress make it appropriate for engine control units, body electronics, and ADAS power supplies. The 5KP24A-E3/54 meets all required stress tests per AEC-Q101 Rev D.
What does the "-E3/54" suffix indicate in 5KP24A-E3/54?
The "-E3" denotes RoHS-compliant, commercial-grade construction with JESD 201 class 1A whisker resistance; "/54" specifies the preferred packaging code - 13-inch diameter paper tape and reel containing 800 units. This ordering format ensures consistent logistics handling and automated assembly compatibility. The 5KP24A-E3/54 is supplied in this configuration directly from Vishay's production line.
How does the 5KP24A-E3/54 differ from bidirectional TVS diodes?
The 5KP24A-E3/54 is unidirectional and functions only as a reverse-biased clamp - it conducts during negative transients relative to its cathode. Unlike bidirectional variants, it does not suppress positive-going surges on AC or floating lines. This makes the 5KP24A-E3/54 ideal for DC power rails where polarity is fixed, offering lower leakage and tighter VBR tolerance than equivalent bidirectional parts.
Can the 5KP24A-E3/54 be used in parallel for higher surge current handling?
No - paralleling multiple 5KP24A-E3/54 devices is not recommended due to mismatched dynamic impedance and uneven current sharing under transient conditions, which risks thermal runaway in one unit. For higher current capability, select a single higher-rated device (e.g., 5KP26A or 5KP28A) or consult Vishay's application note AN949 for verified multi-device layout techniques. The 5KP24A-E3/54 is characterized and tested as a standalone component.
