It features a 30 V standoff voltage (VWM = 25.6 V), 28.5–31.5 V breakdown range (VBR), 600 W peak pulse power (10/1000 μs), 14.5 A peak pulse current (IPPM), and 41.4 V clamping voltage (VC) - enabling reliable protection of MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KA30AHE3/54 datasheet, P6KA30AHE3/54 pinout, P6KA30AHE3/54 application, or P6KA30AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction rating, DO-15 package compatibility, and verified clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable operation up to TJ = 185 °C. Its unidirectional polarity and low incremental surge resistance ensure fast response (<1 ns) and minimal voltage overshoot during transients induced by inductive switching or ESD events.
The device complies with AEC-Q101 stress testing for automotive reliability and supports soldering per J-STD-002 and JESD 22-B102. Its DO-204AC (DO-15) package features matte tin-plated leads and UL 94 V-0 molded epoxy encapsulation - meeting stringent environmental and mechanical requirements for under-hood and industrial deployments.
Key Specifications

|---|---|
| VWM (Stand-off Voltage) | 25.6 V - maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 28.5–31.5 V at 1 mA - precise voltage threshold where avalanche conduction initiates reliably under transient stress. |
| VC (Clamping Voltage) | 41.4 V at IPPM = 14.5 A - limits downstream voltage exposure during 10/1000 μs surges, protecting 3.3 V/5 V/12 V logic and power stages. |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity for standardized 10/1000 μs waveform; enables compliance with IEC 61000-4-5 Level 4. |
| TJ max. | 185 °C - extended junction temperature rating supports operation in high-ambient environments such as engine control units and motor drives. |
| Polarity | Unidirectional - provides reverse-biased surge suppression only; requires correct orientation relative to DC bias rail. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Same VWM (25.6 V), slightly higher VC (48.4 V), SMB package (surface-mount), 600 W rating | Requires PCB rework for SMT layout; lacks AEC-Q101 qualification | Select when board space is constrained and automotive qualification is not required. |
| 1.5KE30A | Same VWM and VBR range, through-hole DO-201 package, 1500 W rating but larger footprint and higher VC (48.4 V) | Higher power handling but slower response due to larger junction capacitance (~150 pF vs. ~50 pF) | Prefer for legacy designs needing higher single-pulse energy absorption without layout change. |
Compared with P6KA30AHE3/54, SMBJ30A offers compact SMT integration but sacrifices automotive qualification and clamping tightness, while 1.5KE30A delivers greater surge energy capacity at the cost of response speed and board area - making P6KA30AHE3/54 optimal for space-constrained, high-reliability automotive and industrial deployments.

FAQ
What is the maximum clamping voltage of the P6KA30AHE3/54 under standard test conditions?
The P6KA30AHE3/54 has a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current (IPPM = 14.5 A) using the 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and ensures downstream components remain within safe voltage limits during surge events. The clamping performance is guaranteed across the full operating temperature range and is integral to the device's AEC-Q101 qualification.
Is the P6KA30AHE3/54 qualified for automotive applications?
Yes, the P6KA30AHE3/54 is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 88368, Revision: 20-Dec-13). It undergoes stress testing for high-temperature operating life, temperature cycling, and humidity bias to meet automotive reliability standards. Its 185 °C maximum junction temperature and DO-15 package with matte tin leads further support under-hood deployment in engine control units and body electronics.
What does the "HE3/54" suffix indicate in P6KA30AHE3/54?
The "HE3" suffix denotes RoHS-compliant construction and JESD 201 Class 2 whisker resistance, while "/54" specifies the preferred packaging: 4000 units per 13-inch paper tape and reel. This packaging format is optimized for automated SMT placement despite the device being axial-leaded - enabling compatibility with pick-and-place equipment via carrier tape feeders calibrated for DO-15 components.
How does the P6KA30AHE3/54 compare to the P6KA30 variant in terms of electrical performance?
The P6KA30AHE3/54 offers tighter breakdown voltage tolerance (28.5–31.5 V) versus the standard P6KA30 (27.0–33.0 V), resulting in more predictable clamping onset and reduced unit-to-unit variation in surge response. Both share identical VWM (25.6 V), PPPM (600 W), and TJ max. (185 °C), but the "A" grade improves design margin for applications requiring precise voltage threshold control, such as regulated power supply inputs.
Can the P6KA30AHE3/54 be used in bidirectional configurations?
No, the P6KA30AHE3/54 is strictly unidirectional, as stated in the datasheet's FEATURES section. It conducts only in reverse avalanche mode and must be oriented with the cathode toward the protected line. For bidirectional protection, two P6KA30AHE3/54 devices may be connected in series opposing configuration, but this is not recommended - instead, use a purpose-built bidirectional TVS such as the SMAJ30A or SMCJ30CA for symmetrical clamping.
