Product details
Overview
P6SMB16CA-E3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 13.6 V stand-off voltage (VWM), 16.8 V minimum breakdown voltage (VBR), 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB16CA-E3/52 datasheet, P6SMB16CA-E3/52 pinout, P6SMB16CA-E3/52 application, or P6SMB16CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.34), AEC-Q101 qualification eligibility (via HE3/HM3 variants), RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling protection against ESD, lightning-induced surges, and inductive switching transients.
The device is rated for 150 °C maximum junction temperature and exhibits low incremental surge resistance, supporting repetitive 0.01% duty cycle pulses. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), requiring minimal PCB copper area (0.2" × 0.2" per terminal) for full 600 W pulse handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown, min) | 15.2 V - Minimum voltage at which device enters avalanche conduction under 1.0 mA test current; ensures reliable turn-on above normal operating voltage. |
| VC (Clamping, max) | 22.5 V - Maximum voltage seen by protected circuit at 26.7 A peak pulse; determines worst-case overvoltage stress during surge. |
| IPPM | 26.7 A - Peak pulse current supported with 10/1000 μs waveform; directly relates to energy absorption (600 W). |
| PPPM | 600 W - Peak pulse power dissipation capability; enables robust protection against IEC 61000-4-5 Level 3/4 surges. |
| TJ max | 150 °C - Maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments. |
| Package | SMB (DO-214AA) - Surface-mount package with 0.220" × 0.130" footprint; optimized for automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Bidirectional construction has no polarity marking - both terminals are electrically symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals serve as interchangeable surge current entry/exit points; no cathode band marking required for bidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns - e.g., RS-485, CAN, USB D+/D−. |
| 600 W peak pulse power | Supports IEC 61000-4-5 4 kV surge testing (line-to-earth) with margin when mounted on recommended 0.2" × 0.2" copper pads. |
| Low clamping ratio (VC/VBR = 1.34) | Minimizes overvoltage exposure to downstream ICs - critical for 3.3 V or 5 V logic interfaces where <25 V clamping is mandatory. |
| AEC-Q101 qualification path | HE3/HM3 suffix variants available for automotive applications; P6SMB16CA-E3/52 itself is commercial-grade but shares identical die and construction. |
| MSL Level 1 (260 °C peak) | Allows unlimited floor life and standard reflow profiles without baking - reduces manufacturing complexity and cost. |
Applications
| Automotive Sensor Interface Protection | Industrial PLC I/O Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA | Same VWM (13.6 V), lower PPPM (400 W), larger SMA package (DO-214AC), higher RθJA (140 °C/W). | Lower surge margin; suitable only for non-automotive consumer applications with derated layout. | Select when cost sensitivity outweighs surge headroom and board space allows larger footprint. |
| 1.5KE16CA | Same VWM and VC, but axial leaded DO-201 package; 1500 W PPPM but incompatible with SMT assembly. | Requires through-hole assembly and manual rework; unsuitable for high-volume automated production. | Choose only for legacy repair, prototyping, or low-volume industrial controls where hand-soldering is acceptable. |
Compared with SMAJ16CA and 1.5KE16CA, P6SMB16CA-E3/52 delivers optimal balance of 600 W surge capacity, SMB footprint compatibility with high-speed SMT lines, and commercial-grade reliability - making it the preferred choice for volume production of automotive-adjacent and industrial IoT edge devices.

FAQ
What is the clamping voltage of P6SMB16CA-E3/52 at its rated peak pulse current?
The P6SMB16CA-E3/52 has a maximum clamping voltage (VC) of 22.5 V at 26.7 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and defines the upper voltage limit imposed on protected circuits during surge events. The clamping performance is consistent in both directions due to its bidirectional design, and the 22.5 V value ensures compatibility with 24 V systems where transient overshoot must remain below 25 V.
Is P6SMB16CA-E3/52 suitable for automotive applications?
P6SMB16CA-E3/52 is RoHS-compliant commercial-grade, but not AEC-Q101 qualified out-of-the-box. However, Vishay offers functionally identical variants with HE3 or HM3 suffixes (e.g., P6SMB16CAHE3_B) that are AEC-Q101 qualified and share the same die, SMB package, and electrical characteristics. For production automotive use, engineers should specify the HE3/HM3 version; P6SMB16CA-E3/52 remains appropriate for automotive-adjacent industrial or infotainment subsystems where qualification is not mandated.
How does the bidirectional nature of P6SMB16CA-E3/52 affect PCB layout?
The bidirectional construction of P6SMB16CA-E3/52 eliminates polarity marking - both terminals are electrically identical, so no orientation check is needed during placement. This simplifies PCB layout by removing the need for silkscreen polarity indicators or asymmetric pad design. Engineers can route either terminal to the signal line and the other to ground (or chassis), enabling flexible placement in differential or floating topologies such as RS-485 buses or isolated sensor bridges without risk of reverse installation.
What is the thermal resistance of P6SMB16CA-E3/52 and how does it impact surge handling?
P6SMB16CA-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W. These values assume mounting on 0.2" × 0.2" copper pads per terminal. The low RθJL enables effective heat transfer during short-duration surges, allowing full 600 W pulse power dissipation without exceeding the 150 °C maximum junction temperature. Reducing pad size or omitting thermal vias increases RθJA, derating surge capability - hence adherence to Vishay's recommended layout is critical for rated performance.
Can P6SMB16CA-E3/52 replace unidirectional TVS diodes like P6SMB16A-E3/52 in existing designs?
No - P6SMB16CA-E3/52 is bidirectional and cannot directly replace unidirectional P6SMB16A-E3/52 without circuit review. While both share identical VWM, VBR, and VC ratings, the unidirectional version conducts only in reverse bias and blocks forward current, whereas the CA variant conducts symmetrically. Substitution is only safe in AC-coupled, floating, or differential signal paths; it would cause malfunction in DC-biased circuits like 24 V power rail protection where forward conduction must be blocked.
