Product details
Overview
P6KA16AHE3/54 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 13.6 V standoff voltage (VWM), 15.2–16.8 V breakdown range (VBR), 600 W peak pulse power (10/1000 μs), 26.7 A peak pulse current (IPPM), and clamps to 22.5 V at rated surge - deployed in automotive engine control units, industrial motor drives, and telecom power supplies.
For engineers reviewing the P6KA16AHE3/54 datasheet, P6KA16AHE3/54 pinout, P6KA16AHE3/54 application, or P6KA16AHE3/54 equivalent, key selection criteria include unidirectional polarity, DO-204AC (DO-15) package compatibility, AEC-Q101 qualification, 185 °C junction temperature rating, and clamping performance under repetitive 10/1000 μs transients.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping across temperature. Its unidirectional structure provides low forward voltage (VF = 3.5 V at 50 A) and fast response to ESD and switching transients.
Rated for TJ = –65 °C to +185 °C, it supports high-reliability automotive and industrial environments. The device meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability requirements, with matte tin-plated leads solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13.6 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 15.2–16.8 V at 1 mA - Tight tolerance ensures predictable turn-on during transients without false triggering. |
| VC (Clamping Voltage) | 22.5 V at IPPM = 26.7 A - Limits downstream voltage stress on protected ICs or MOSFETs during surge events. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Sustains high-energy surges common in automotive load-dump or inductive switch-off scenarios. |
| TJ max. | +185 °C - Enables operation in under-hood automotive or high-ambient industrial environments without derating. |
| Polarity | Unidirectional - Protects against positive transients only; requires correct orientation relative to DC bias. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, molded epoxy case with UL 94 V-0 rating. Cathode indicated by color band on body. Leads are matte tin-plated, compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance return in unidirectional configuration; completes clamping loop during positive transients. |
| Cathode | Protected line connection / Surge input | Connected to the line being protected (e.g., 12 V rail); conducts when transient exceeds VBR, shunting energy to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process ensures stable VBR and low leakage (<1 μA at VWM, TJ = 150 °C). |
| High-temperature capability | 185 °C maximum junction temperature enables use in engine compartments and sealed industrial enclosures. |
| Low clamping ratio | VC/VBR ≈ 1.38 - Minimizes overvoltage stress on downstream components during surge events. |
| AEC-Q101 qualification | Validated for automotive applications including temperature cycling, humidity bias, and high-temperature reverse bias. |
| Solderability & reliability | Meets JESD 201 Class 2 whisker resistance and JESD 22-B106 275 °C/10 s solder dip specification. |
Applications
| Automotive Engine Control Unit (ECU) | Industrial Motor Drive Power Input |
|---|---|

IC Role / Device Role / Timing Role: Point-of-use TVS on each protected node, mounted close to connector or IC pad. Use Value: Fast response time and low incremental surge resistance ensure sub-100 ns clamping, preserving signal integrity on 20 kbps LIN lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same DO-214AC package; lower PPPM (400 W), higher VC (26.0 V at 20.1 A), non-AEC-Q101 qualified. | Not suitable for automotive under-hood use; limited to commercial-grade industrial or consumer systems. | Select if cost sensitivity outweighs automotive qualification and 600 W surge headroom. |
| 1.5KE16A | DO-201AD package; same VWM/VBR range but higher VF (4.5 V), larger footprint, no AEC-Q101 qualification. | Larger thermal mass but incompatible with space-constrained PCB layouts requiring DO-15 form factor. | Choose only when legacy board design mandates DO-201AD mechanical compatibility. |
Compared with SMAJ16A and 1.5KE16A, P6KA16AHE3/54 delivers superior automotive readiness (AEC-Q101), higher surge capacity (600 W vs. 400 W or 1500 W with larger thermal envelope), and tighter clamping (22.5 V vs. 26.0 V or 27.7 V), all within the compact DO-15 footprint required for dense ECU layouts.

FAQ
What is the maximum operating temperature for P6KA16AHE3/54?
P6KA16AHE3/54 has a maximum junction temperature (TJ max.) of +185 °C, enabling reliable operation in under-hood automotive locations and sealed industrial enclosures. This rating is validated per AEC-Q101 stress tests and supported by its passivated junction construction and UL 94 V-0 molding compound.
Is P6KA16AHE3/54 suitable for bidirectional transient protection?
No, P6KA16AHE3/54 is unidirectional only, as confirmed in the Vishay datasheet. It protects against positive-going transients on a biased line. For bidirectional protection, a separate part such as P6SMB16CA or equivalent dual-diode configuration is required.
What does the "HE3/54" suffix indicate in P6KA16AHE3/54?
The HE3/54 suffix denotes RoHS-compliant, AEC-Q101-qualified packaging: HE3 indicates matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, and /54 specifies 4000-unit quantity in 13-inch paper tape and reel delivery format per Vishay's ordering convention.
How does the clamping voltage of P6KA16AHE3/54 compare to its breakdown voltage?
P6KA16AHE3/54 clamps to 22.5 V at 26.7 A (IPPM), while its VBR range is 15.2–16.8 V. This yields a clamping ratio (VC/VBR) of ~1.34–1.48, reflecting efficient voltage limiting with minimal overvoltage margin - critical for protecting 24 V-rated ICs in automotive and industrial systems.
Can P6KA16AHE3/54 be used in place of P6KA16HE3/54?
No - P6KA16AHE3/54 and P6KA16HE3/54 differ in VBR tolerance: P6KA16AHE3/54 has tighter 10 % tolerance (15.2–16.8 V), whereas P6KA16HE3/54 has wider 15 % (14.4–17.6 V). Substitution may affect clamping consistency and system-level surge margin verification.
