Product details
Overview
P6KA24HE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 21.6 V minimum breakdown voltage (VBR), 19.4 V standoff voltage (VWM), 600 W peak pulse power (10/1000 μs), 17.3 A peak pulse current (IPPM), and clamps to ≤34.7 V at rated surge - deployed in automotive power supplies, industrial sensor interfaces, and DC-DC converter input rails.
For engineers reviewing the P6KA24HE3/54 datasheet, P6KA24HE3/54 pinout, P6KA24HE3/54 application, or P6KA24HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction rating, DO-204AC (DO-15) package compatibility, and verified clamping performance under repetitive 10/1000 μs transients in high-reliability embedded systems.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable operation up to TJ = 185 °C. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
The device delivers consistent 600 W surge handling per IEC 61000-4-5-compliant 10/1000 μs waveform at 0.01 % duty cycle, with low incremental surge resistance ensuring minimal voltage overshoot during fast-rising transients like inductive switch-off events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 19.4 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC bias margin. |
| VBR (min/max) | 21.6 V / 26.4 V at 1 mA - Confirmed breakdown range ensures predictable turn-on across production lot and temperature. |
| VC @ IPPM | ≤34.7 V at 17.3 A - Clamping voltage limits downstream IC stress during 600 W surge events. |
| IPPM | 17.3 A - Peak surge current capability with 10/1000 μs waveform; validated for automotive load-dump immunity. |
| TJ max. | +185 °C - Enables placement near hot components (e.g., power MOSFETs, inductors) without derating. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with matte tin-plated leads, RoHS-compliant and whisker-tested (JESD 201 Class 2). |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode indicated by color band. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, rated for 275 °C solder dip (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts only during forward surge or fault conditions. |
| Cathode | Clamping reference terminal | Marked by color band; connected to higher-potential side; initiates avalanche breakdown when reverse VWM is exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standards. |
| 185 °C junction rating | Supports operation in engine bay, powertrain, and under-hood modules without thermal derating penalties. |
| 600 W peak pulse power (10/1000 μs) | Meets ISO 7637-2 Pulse 1, 2a, 3a/b and IEC 61000-4-5 Level 3 surge immunity requirements. |
| Low clamping ratio (VC/VBR ≈ 1.62) | Minimizes overvoltage stress on downstream MOSFETs, regulators, and microcontrollers during transients. |
| Uni-directional polarity | Prevents unintended conduction in DC-biased applications such as 24 V supply rails and CAN bus termination networks. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5A | Same VWM (19.4 V), but lower PPPM (400 W); DO-214AC (SMA) surface-mount package. | Not suitable for through-hole legacy designs or high-temperature axial mounting; lacks AEC-Q101 certification. | Select when board space is constrained and reflow assembly is used; verify thermal pad layout for 400 W dissipation. |
| 1.5KE24A | Higher VC (38.9 V), same VWM, larger DO-201AD package; no AEC-Q101 qualification. | Used in non-automotive industrial power supplies; not recommended for automotive or high-reliability sensor nodes. | Choose only for cost-sensitive, non-automotive applications where 4.2 V higher clamping voltage is acceptable. |
Compared with SMAJ24A-E3/5A and 1.5KE24A, the P6KA24HE3/54 provides superior automotive qualification, tighter clamping (34.7 V vs. ≥38.9 V), and proven 185 °C operation - making it the preferred choice for under-hood and safety-critical 24 V system protection.

FAQ
What is the maximum operating temperature for the P6KA24HE3/54?
The P6KA24HE3/54 has a maximum junction temperature (TJ) of +185 °C, validated per AEC-Q101 stress tests. This allows direct mounting near heat sources such as power inductors or MOSFETs in automotive and industrial environments without thermal derating below 125 °C ambient. The P6KA24HE3/54 maintains full 600 W surge capability up to TJ = 150 °C per Fig. 2 in the datasheet.
Is the P6KA24HE3/54 suitable for automotive applications?
Yes - the P6KA24HE3/54 is explicitly AEC-Q101 qualified and rated for TJ = -65 °C to +185 °C. It meets automotive surge immunity standards including ISO 7637-2 Pulse 1 and 2a, and supports under-hood deployment in engine control units, body control modules, and ADAS power domains. The P6KA24HE3/54 HE3 suffix confirms RoHS compliance and JESD 201 Class 2 whisker resistance.
What does the "HE3/54" suffix mean in P6KA24HE3/54?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, while "/54" specifies the packaging format: 4000 units per 13-inch paper tape and reel. This ordering code ensures traceable, automotive-grade material flow and automated SMT-compatible handling - critical for high-volume P6KA24HE3/54 deployments in Tier 1 manufacturing.
How does the clamping voltage of P6KA24HE3/54 compare to similar 24 V TVS diodes?
The P6KA24HE3/54 clamps to ≤34.7 V at 17.3 A (10/1000 μs), achieving a clamping ratio (VC/VBR) of ~1.62 - tighter than standard alternatives like 1.5KE24A (VC = 38.9 V). This lower clamping voltage directly reduces stress on downstream 36 V-rated regulators and gate drivers, improving system-level surge survivability without additional cascaded protection stages in the P6KA24HE3/54 design.
Can P6KA24HE3/54 replace P6KA24A in existing designs?
Yes - P6KA24HE3/54 and P6KA24A share identical electrical specs (VWM = 19.4 V, VBR = 21.6–26.4 V, VC ≤ 34.7 V) and DO-204AC package. The HE3/54 variant adds RoHS compliance, AEC-Q101 requalification, and JESD 201 Class 2 whisker resistance. No PCB or schematic changes are needed; the P6KA24HE3/54 is a drop-in upgrade for enhanced reliability and compliance.
