Product details
Overview
P6KE16HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 16 V breakdown voltage (VBR min = 15.2 V, max = 16.8 V), 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage at 26.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs to safeguard microcontrollers against load-dump transients.
For engineers reviewing the P6KE16HE3/54 datasheet, P6KE16HE3/54 pinout, P6KE16HE3/54 application, or P6KE16HE3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, junction temperature derating above 25 °C, AEC-Q101 qualification status, and DO-15 package lead-form compatibility with legacy PCB footprints.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but avalanches rapidly (<1 ns response) when reverse voltage exceeds VBR, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (≤1.0 µA at 13.6 V).
Thermal design relies on its 20 °C/W junction-to-lead thermal resistance and 75 °C/W junction-to-ambient rating; power dissipation is limited to 5.0 W on infinite heatsink at TL = 75 °C. The HE3 suffix confirms AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and RoHS compliance - critical for automotive under-hood deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V at 1.0 mA test current - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 13.6 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA; sets safe DC rail margin |
| VC @ IPPM | 22.5 V at 26.7 A (10/1000 µs) - clamping voltage must stay below protected IC's absolute max rating (e.g., 24 V MCU I/O) |
| PPPM | 600 W - peak transient energy handling capacity; determines survivability against ISO 7637-2 Pulse 5a (load dump) |
| TJ max | 175 °C - enables operation in engine compartment environments without thermal shutdown |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package compatible with automated insertion and wave soldering |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with matte tin-plated leads; cathode indicated by color band on one end; total length ≥25.4 mm, body diameter 3.6 mm × 2.6 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential node in uni-directional configuration; carries surge current during clamping |
| Cathode | Reverse-biased avalanche terminal | Connected to protected line (e.g., 12 V rail); avalanche initiates here when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and low leakage drift over 1000-hour HTOL testing |

| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control, body electronics, and ADAS sensors |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes voltage overshoot during clamping - critical for protecting 16 V-tolerant interface ICs |
| Matte tin plating, J-STD-002 compliant | Enables reliable solder wetting and intermetallic formation in lead-free reflow processes |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

IC Role / Device Role / Timing Role: Primary clamp on +5 V rail upstream of USB switch and PHY ICs. Use Value: Maintains VC < 6.5 V at 5 A surge, ensuring USB transceivers remain within 6 V absolute maximum rating during repeated plug/unplug events. |
Use Scenario: Analog telephone line interface (POTS) exposed to lightning-induced surges and AC power cross-talk. IC Role / Device Role / Timing Role: First-stage protector on tip/ring lines before SLIC and codec ICs. Use Value: Absorbs 10/1000 µs surges up to 600 W while holding clamping voltage below 30 V - sufficient to prevent damage to -48 V biased line drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same VBR range (15.2–16.8 V), but SMA package (surface-mount); 400 W PPPM; no AEC-Q101 qualification | Used in space-constrained consumer PCBs where reflow assembly is preferred over through-hole | Select SMAJ16A only if board layout allows SMD placement and automotive qualification is not required |
| 1.5KE16A | Same DO-15 package and VBR, but 1500 W PPPM; higher IPPM (109 A); commercial grade only (no AEC-Q101) | Deployed in industrial motor drives where higher surge immunity is needed but automotive reliability is unnecessary | Choose 1.5KE16A when surge energy exceeds 600 W but AEC-Q101 is not mandated |
Compared with SMAJ16A and 1.5KE16A, P6KE16HE3/54 uniquely balances AEC-Q101 qualification, DO-15 through-hole compatibility, and 600 W surge capability - making it the optimal choice for cost-sensitive automotive modules requiring proven under-hood reliability without redesigning the footprint.

FAQ
What is the meaning of the 'HE3' suffix in P6KE16HE3/54?
The HE3 suffix in P6KE16HE3/54 indicates three critical qualifications: RoHS compliance, AEC-Q101 automotive reliability certification, and JESD 201 Class 2 whisker resistance. This distinguishes it from commercial-grade variants like P6KE16A-E3/54, which lack AEC-Q101 validation. P6KE16HE3/54 is therefore approved for use in automotive powertrain and chassis modules where extended temperature cycling and long-term stability are mandatory.
How does P6KE16HE3/54 differ from P6KE16A in practical circuit design?
P6KE16HE3/54 differs from P6KE16A primarily in qualification and process control: both share identical electrical specs (VBR, VC, PPPM), but P6KE16HE3/54 undergoes additional AEC-Q101 stress testing (including 1000-hour HTOL and temperature cycling) and uses whisker-resistant lead plating. In practice, P6KE16HE3/54 is specified for automotive under-hood applications, whereas P6KE16A is restricted to commercial-grade equipment where qualification is not required.
Can P6KE16HE3/54 be used in bi-directional protection circuits?
No, P6KE16HE3/54 is a uni-directional TVS diode and must not be used for bi-directional protection. Its cathode marking and asymmetric IV curve mean it conducts only in reverse avalanche mode; forward conduction is limited to ~3.5 V at 50 A. For bi-directional applications such as AC line or data bus protection, the CA-suffixed variant (e.g., P6KE16CA) is required - which has symmetrical breakdown in both polarities and no polarity marking.
What is the maximum allowable lead temperature during soldering for P6KE16HE3/54?
The maximum solder dip temperature for P6KE16HE3/54 is 275 °C for up to 10 seconds, per JESD 22-B106. This limit applies to wave soldering processes; for reflow, peak temperature must not exceed 260 °C (per JEDEC J-STD-020). Exceeding these thresholds risks delamination of the epoxy molding compound or degradation of the glass-passivated junction, potentially increasing leakage or shifting VBR.
How is the clamping voltage VC of P6KE16HE3/54 verified in production testing?
VC for P6KE16HE3/54 is verified per production lot using a 10/1000 µs surge waveform at IPPM = 26.7 A, measured with calibrated pulse generators and high-bandwidth oscilloscopes. Each lot undergoes statistical sampling per AQL Level II (MIL-STD-105E), and VC must not exceed 22.5 V. This test ensures consistent clamping performance across all P6KE16HE3/54 units shipped - critical for maintaining system-level surge immunity margins.
