Product details
Overview
P6KE16CHE3/54 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 nominal breakdown voltage (VBR = 15.2–16.8 V at IT = 1.0 mA), 13.6 V stand-off voltage (VWM), 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 P6KE16CHE3/54 datasheet, P6KE16CHE3/54 pinout, P6KE16CHE3/54 application, or P6KE16CHE3/54 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, and verified 175 °C junction temperature rating for under-hood automotive environments.
Technical Context
The P6KE16CHE3/54 operates as a bi-directional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM = 13.6 V).
It delivers 600 W transient power handling per 10/1000 μs waveform with 0.01 % duty cycle, supported by low incremental surge resistance and fast response time (<1.0 ns). Thermal resistance is RθJL = 20 °C/W (junction-to-lead), enabling reliable operation up to TJ = 175 °C when mounted on PCB copper land patterns meeting JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V at IT = 1.0 mA - defines guaranteed avalanche onset range for design margining |
| VWM | 13.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | ≤22.5 V at 26.7 A - clamping voltage limiting downstream IC stress during surge events |
| PPPM | 600 W (10/1000 μs) - peak transient energy absorption capacity per pulse |
| TJ max. | +175 °C - enables use in high-temperature automotive engine control units and industrial motor drives |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB copper pour sizing |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; RoHS-compliant and AEC-Q101 qualified (HE3 suffix). No polarity marking - bi-directional symmetry eliminates cathode/anode orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | Either terminal serves as input/output - no DC bias dependency; connects across protected line and ground or differential pair |
| Lead 1 / Lead 2 | Current conduction path | Leads conduct full surge current (IPPM = 26.7 A); require ≥1.5 mm PCB trace width and thermal relief for 275 °C solder dip |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance (±5 %) and <1.0 μA leakage at VWM, critical for low-power sensor interfaces |
| 600 W peak pulse power (10/1000 μs) | Withstands ISO 7637-2 Pulse 1/2a/5a surges without degradation in automotive ECUs |
| AEC-Q101 qualification | Validated for automotive under-hood applications including temperature cycling (-55 °C to +175 °C) and humidity testing |
| Low clamping ratio (VC/VBR ≈ 1.41) | Minimizes overvoltage stress on downstream 16 V-rated components such as CAN transceivers and ADC inputs |
| DO-204AC (DO-15) footprint | Compatible with legacy through-hole assembly lines and manual rework; 0.300" lead spacing supports IPC-7351B standard land patterns |
Applications
| Automotive Sensor Protection | Industrial Analog Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | DO-214AA package; 600 W rating; VBR = 17.8–19.7 V; VC = 26.0 V @ 23.1 A | Surface-mount only; higher clamping voltage reduces margin for 16 V systems | Preferred where board space is constrained and SMT assembly is mandatory |
| 1.5KE16CA | DO-201AD package; 1500 W rating; VBR = 15.2–16.8 V; VC = 25.5 V @ 59.0 A | Larger footprint and higher surge capacity; not AEC-Q101 qualified | Selected when higher single-pulse energy (e.g., ISO 16750-2 Load Dump) must be absorbed |
Compared with SMBJ16CA and 1.5KE16CA, the P6KE16CHE3/54 offers AEC-Q101 qualification in a cost-optimized through-hole DO-15 package with tighter clamping (22.5 V vs. 25.5–26.0 V), making it optimal for automotive and industrial designs requiring proven reliability and legacy assembly compatibility.

FAQ
What does the "HE3/54" suffix mean in P6KE16CHE3/54?
The HE3 suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" denotes packaging in 13-inch paper tape and reel with 4000 units per reel. This confirms P6KE16CHE3/54 meets automotive reliability requirements and is optimized for automated through-hole insertion. The P6KE16CHE3/54 is fully traceable to Vishay's manufacturing lot controls and material declarations.
Is P6KE16CHE3/54 unidirectional or bidirectional?
P6KE16CHE3/54 is a bi-directional TVS diode - confirmed by the "CA" designation in its full family name (P6KE16CA) and absence of cathode band marking. It provides symmetrical clamping for both positive and negative transients, making it suitable for AC-coupled lines, differential buses, and floating grounds. Unlike unidirectional variants (e.g., P6KE16A), the P6KE16CHE3/54 does not require polarity-aware placement.
What is the maximum clamping voltage of P6KE16CHE3/54 at rated surge current?
The maximum clamping voltage (VC) of P6KE16CHE3/54 is 22.5 V at IPPM = 26.7 A (10/1000 μs waveform), per Vishay Document 88369, page 2. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and directly determines safe operating margins for downstream 16 V-rated ICs. The P6KE16CHE3/54 maintains this clamping performance across its full operating temperature range (-55 °C to +175 °C).
Can P6KE16CHE3/54 replace P6KE16A in existing designs?
No - P6KE16CHE3/54 is bi-directional (CA type), while P6KE16A is unidirectional (A type) with cathode marking and asymmetric forward conduction. Substituting them risks forward-bias failure on negative transients or improper clamping in AC-coupled paths. The P6KE16CHE3/54 must only replace other CA-suffixed parts (e.g., P6KE16CA) with identical VBR, VWM, and package. Always verify layout polarity and grounding topology before substitution.
Does P6KE16CHE3/54 meet UL 497B recognition?
Yes - Vishay Document 88369 states UL recognition QVGQ2 under UL 497B (file E136766) applies to both uni- and bi-directional P6KE devices, including P6KE16CHE3/54. This certification validates its suitability as a primary protector in telecommunications and industrial signal line applications where third-party safety compliance is mandated. The P6KE16CHE3/54 carries no separate UL mark but is covered under Vishay's master listing.
