Product details
Overview
P6SMB16CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 16 V standoff voltage (VWM), 22.5 V clamping voltage (VC) at 26.7 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform - deployed for ESD and surge protection on signal lines and power rails in automotive sensor interfaces and industrial control modules.
For engineers reviewing the P6SMB16CAHE3/52 datasheet, P6SMB16CAHE3/52 pinout, P6SMB16CAHE3/52 application, or P6SMB16CAHE3/52 equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, low incremental surge resistance, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown in both polarities due to its bidirectional construction. It exhibits a typical breakdown voltage (VBR) of 17.1–18.9 V at 1 mA test current and achieves clamping within 1 ns response time under fast-rising transients.
Thermally, it features RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation up to TJ = +150 °C. Its glass-passivated junction and matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 whisker resistance Class 2 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 17.1–18.9 V at 1 mA - Voltage at which device enters avalanche conduction; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 22.5 V at IPPM = 26.7 A - Peak voltage seen by protected circuit during 10/1000 μs surge; limits stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability per 10/1000 μs waveform; supports robust protection against lightning-induced surges. |
| IPPM | 26.7 A - Maximum non-repetitive peak pulse current; determines survivability under standardized surge conditions. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments and high-ambient industrial settings. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with molded UL 94 V-0 compound and matte tin-plated terminals. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal pair | No polarity marking; terminals are functionally identical - enables placement without orientation check during automated assembly. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity testing without derating in standard PCB layouts. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control units, ADAS sensors, and body electronics modules. |
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| MSL Level 1 (J-STD-020) | Allows unlimited floor life and reflow at peak temperature up to 260 °C without preconditioning. |
| Low clamping ratio (VC/VBR ≈ 1.26) | Minimizes voltage overshoot during transient events, reducing risk of latch-up or gate oxide damage in protected MOSFETs or ICs. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential signal pairs or supply-to-ground paths. Use Value: Limits transient voltage to ≤22.5 V during 10/1000 μs surges, preserving signal integrity and preventing reset or damage to 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding digital input/output channels of programmable logic controllers against field-wiring induced surges and ground bounce. IC Role / Device Role / Timing Role: Standoff-connected TVS on each I/O line, referenced to system ground or isolated supply rail. Use Value: Withstands repetitive 600 W pulses at 0.01% duty cycle, enabling long service life in factory automation environments with frequent switching noise. |
| Telecom Line Interface | Consumer Power Adapter Output |
|
Use Scenario: Shielding Ethernet PHYs and PoE injectors from induced lightning surges on unshielded twisted-pair cabling. IC Role / Device Role / Timing Role: Differential-mode TVS across data lines (e.g., TX+/TX−), combined with common-mode chokes. Use Value: Fast 1 ns response and symmetrical clamping ensure minimal jitter injection into high-speed signals while meeting GR-1089-CORE surge requirements. |
Use Scenario: Secondary-side overvoltage suppression on 12 V/19 V DC outputs of wall adapters used in laptops and monitors. IC Role / Device Role / Timing Role: Shunt protector between output rail and ground, sized to absorb residual switching spikes and hot-plug transients. Use Value: 13.6 V VWM provides adequate margin above nominal output while clamping to 22.5 V prevents damage to connected devices' input regulators. |
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), SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for AEC-Q101 automotive use | Select when board space is constrained and surge energy remains below 400 W; verify thermal margin at full load. |
| 1.5KE16CA | Same VWM and bidirectionality, but through-hole DO-201 package, PPPM = 1500 W, slower response (~5 ns) | Requires manual or wave-solder assembly; better for high-energy, low-frequency surges (e.g., AC mains) | Choose for legacy through-hole designs or where higher peak power handling outweighs SMT compatibility needs. |
Compared with SMAJ16CA and 1.5KE16CA, P6SMB16CAHE3/52 delivers optimal balance of AEC-Q101 compliance, 600 W surge capacity, and SMB footprint - making it preferred for new automotive and industrial SMT designs requiring validated reliability and automated manufacturability.

FAQ
What does the "CA" suffix indicate in P6SMB16CAHE3/52?
The "CA" suffix denotes a bidirectional configuration - meaning P6SMB16CAHE3/52 provides symmetrical clamping in both forward and reverse directions, unlike unidirectional variants (e.g., P6SMB16A). This makes P6SMB16CAHE3/52 ideal for protecting AC-coupled or differential signal lines where polarity reversal may occur during transients.
Is P6SMB16CAHE3/52 RoHS-compliant and halogen-free?
Yes, P6SMB16CAHE3/52 carries the HE3 suffix, indicating it is RoHS-compliant and AEC-Q101 qualified. However, it is not halogen-free - that designation applies only to HM3-suffixed variants. The HE3 version uses standard molding compounds meeting UL 94 V-0 and JESD201 Class 2 whisker resistance requirements.
What is the maximum clamping voltage of P6SMB16CAHE3/52 and at what current is it specified?
The maximum clamping voltage (VC) of P6SMB16CAHE3/52 is 22.5 V, measured at the peak pulse current (IPPM) of 26.7 A under a 10/1000 μs double-exponential waveform. This value is guaranteed per the Vishay datasheet and defines the upper voltage limit imposed on protected circuits during standardized surge events.
Can P6SMB16CAHE3/52 be used in place of a unidirectional TVS like P6SMB16A?
No - P6SMB16CAHE3/52 is bidirectional and lacks polarity marking, while P6SMB16A is unidirectional with cathode band identification. Substituting them requires circuit-level verification: P6SMB16CAHE3/52 may conduct during normal forward bias in DC applications, potentially causing malfunction. Use only where bidirectional clamping is explicitly required.
What PCB pad layout is recommended for optimal thermal and surge performance of P6SMB16CAHE3/52?
Vishay specifies mounting P6SMB16CAHE3/52 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and thermal resistance (RθJA = 100 °C/W). Smaller pads reduce surge capability and increase junction temperature - always follow the recommended pad dimensions and copper weight (≥2 oz) for production designs using P6SMB16CAHE3/52.
