Product details
Overview
P6KE16CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features a 16 V breakdown voltage (VBR min/max = 15.2–16.8 V), 13.6 V standoff 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.
For engineers reviewing the P6KE16CAHE3/54 datasheet, P6KE16CAHE3/54 pinout, P6KE16CAHE3/54 application, or P6KE16CAHE3/54 equivalent, this AEC-Q101 qualified TVS offers verified bidirectional surge protection for automotive sensor interfaces, industrial I/O lines, and DC power rail transient suppression where low-leakage (<1.0 μA at VWM) and fast response (<1 ns) are critical.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 GΩ at VWM), then avalanches rapidly when reverse voltage exceeds VBR, limiting transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable breakdown and low leakage across -55 °C to +175 °C operating range.
The P6KE16CAHE3/54 is rated for 600 W peak pulse power (10/1000 μs), 100 A non-repetitive forward surge (8.3 ms half-sine), and exhibits 0.086 %/°C temperature coefficient of VBR. Its DO-15 package provides 20 °C/W junction-to-lead thermal resistance, enabling reliable operation without heatsinking in moderate-duty applications.

FAQ
What is the breakdown voltage range specified for P6KE16CAHE3/54?
The P6KE16CAHE3/54 has a minimum breakdown voltage (VBR) of 15.2 V and a maximum of 16.8 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This 10.5 % tolerance ensures predictable clamping onset while accommodating process variation and temperature drift up to 0.086 %/°C.
Is P6KE16CAHE3/54 suitable for automotive applications?
Yes, P6KE16CAHE3/54 is AEC-Q101 qualified and rated for operation from -55 °C to +175 °C junction temperature. Its DO-15 package meets JESD201 Class 2 whisker resistance, and its 600 W surge capability aligns with ISO 7637-2 Pulse 1/2a/3a requirements for 12 V vehicle systems.
How does the bidirectional configuration of P6KE16CAHE3/54 affect circuit design?
The P6KE16CAHE3/54 has no polarity marking and functions identically in both directions, simplifying PCB layout and eliminating orientation errors during assembly. This makes it ideal for AC-coupled lines, differential buses, or any application where voltage polarity reversal is possible during transients.
What is the maximum clamping voltage of P6KE16CAHE3/54 under surge conditions?
The P6KE16CAHE3/54 clamps to a maximum of 22.5 V when subjected to its rated 26.7 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is guaranteed across temperature and ensures safe operation for 15 V logic and analog components downstream.
Does P6KE16CAHE3/54 require a heatsink for standard operation?
No, P6KE16CAHE3/54 does not require a heatsink under typical transient conditions due to its 20 °C/W junction-to-lead thermal resistance and 5.0 W steady-state power dissipation rating. Thermal management is only needed for sustained high-duty-cycle surges exceeding datasheet derating curves.
