Product details
Overview
P6KE16C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 16 V breakdown voltage (VBR min 15.2 V, max 16.8 V at 1.0 mA), and clamps to ≤22.5 V at 26.7 A peak pulse current - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE16C-E3/73 datasheet, P6KE16C-E3/73 pinout, P6KE16C-E3/73 application, or P6KE16C-E3/73 equivalent, key selection criteria include bi-directional clamping capability, 175 °C maximum junction temperature, RoHS-compliant matte tin-plated leads, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical avalanche behavior in both polarities, enabling transient suppression on AC-coupled or floating signal paths. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, critical for consistent clamping under repetitive 10/1000 μs surges at 0.01% duty cycle.
The P6KE16C-E3/73 exhibits a typical thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), supporting operation up to 175 °C junction temperature. Its 1.0 mA test current and 0.086 %/°C temperature coefficient of VBR ensure predictable voltage drift across temperature ranges in embedded control systems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | Surface-mount SMB package (vs. through-hole DO-15); same VBR range and 600 W rating | Requires PCB redesign for SMT assembly; lower profile suits space-constrained designs | Select when board real estate is limited and reflow compatibility is required |
| 1.5KE16CA | Higher 1500 W peak pulse power; larger DO-201AE package; identical VBR and bi-directional function | Better suited for higher-energy surges (e.g., telecom central office); not drop-in due to footprint mismatch | Select when system-level surge testing exceeds IEC 61000-4-5 Level 4 requirements |
Compared with SMBJ16CA and 1.5KE16CA, the P6KE16C-E3/73 offers proven through-hole robustness for serviceable industrial equipment, balanced surge margin for automotive Grade 3 compliance, and cost-effective qualification for volume OEM production without SMT infrastructure investment.

FAQ
What does the "C" suffix indicate in P6KE16C-E3/73?
The "C" in P6KE16C-E3/73 denotes bi-directional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike uni-directional variants (e.g., P6KE16A), the P6KE16C-E3/73 has no cathode marking and functions identically regardless of polarity applied across its terminals, making it ideal for AC signal lines or floating bus protection where polarity is undefined.
Is P6KE16C-E3/73 AEC-Q101 qualified?
Yes, P6KE16C-E3/73 is AEC-Q101 qualified - confirmed in Vishay's official documentation (Document Number 88369, Revision 18-Sep-12). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and highly accelerated life testing, validating P6KE16C-E3/73 for use in automotive powertrain, chassis, and body electronics where reliability under thermal and electrical stress is mandatory.
What is the maximum clamping voltage of P6KE16C-E3/73 at rated surge current?
The maximum clamping voltage (VC) of P6KE16C-E3/73 is 22.5 V at 26.7 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events and is critical for ensuring downstream components - such as 3.3 V or 5 V logic ICs - remain within their absolute maximum ratings when P6KE16C-E3/73 is correctly implemented.
How does P6KE16C-E3/73 differ from P6KE16A-E3/73?
P6KE16C-E3/73 is bi-directional, while P6KE16A-E3/73 is uni-directional - meaning the latter has a defined cathode (marked with band) and only clamps reverse-polarity transients. The P6KE16C-E3/73 provides symmetrical protection for AC-coupled or differential signals, whereas P6KE16A-E3/73 is used on DC rails where polarity is fixed. Their VBR, VWM, and VC values are nearly identical, but circuit placement and grounding strategy differ significantly between the two variants.
What is the lead finish and solderability specification for P6KE16C-E3/73?
P6KE16C-E3/73 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 for solderability, and meets JESD 201 Class 1A whisker resistance. The E3 suffix confirms RoHS compliance and suitability for wave and hand soldering up to 275 °C for 10 seconds (per JESD 22-B106), supporting both automated and repair-friendly assembly processes in industrial and automotive manufacturing environments.
