Product details
Overview
P6SMB13CA-E3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 13 V standoff voltage (VWM), 18.2 V maximum clamping voltage (VC) at 33.0 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - commonly deployed to protect MOSFETs, sensor interfaces, and IC power rails in industrial and automotive electronics.
For engineers reviewing the P6SMB13CA-E3/52 datasheet, P6SMB13CA-E3/52 pinout, P6SMB13CA-E3/52 application, or P6SMB13CA-E3/52 equivalent, key selection considerations include bidirectional surge suppression capability, SMB (DO-214AA) package compatibility, AEC-Q101 qualification eligibility (via HE3/HM3 variants), thermal resistance (RθJA = 100 °C/W), and low incremental surge resistance for fast transient response.
Technical Context
This bidirectional TVS diode operates symmetrically across both polarities, delivering identical clamping behavior during positive and negative transients. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
The device is rated for 600 W peak pulse power (10/1000 μs), supports 100 A non-repetitive forward surge current (IFSM) in unidirectional configurations, and maintains operation over -65 °C to +150 °C junction temperature range - enabling use in harsh environments without derating below 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 11.1 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 12.4 V (min) to 13.7 V (max) at 1.0 mA test current - precise voltage threshold where avalanche conduction initiates |
| VC (Clamping Voltage) | 18.2 V at 33.0 A IPPM - peak voltage seen by protected circuit during worst-case 600 W transient |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity for standardized 10/1000 μs surge waveform per IEC 61000-4-5 |
| RθJA | 100 °C/W - thermal resistance from junction to ambient air on standard 0.2" × 0.2" copper pads; dictates derating above 25 °C |
| ID (Leakage Current) | 5.0 μA max at VWM - minimal standby power loss and negligible loading on sensitive signal lines |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking for bidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (negative polarity) | Conducts during negative-going surges; forms symmetrical path with cathode for bidirectional clamping |
| Cathode | Transient current entry point (positive polarity) | Conducts during positive-going surges; paired with anode to enable full-cycle protection without external polarity management |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity awareness or external diode pairing |
| 600 W peak pulse power | Meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial and automotive subsystems |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage exposure to downstream ICs - critical for 3.3 V or 5 V logic interface protection |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without moisture-induced failure; no bake-out required prior to assembly |
| AEC-Q101 qualification option | HE3/HM3 variants available for automotive applications requiring validated reliability under temperature cycling and HTRB stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Same SMB package, identical VWM (11.1 V), VC (18.2 V), and PPPM (600 W); minor variation in VBR tolerance (12.4–13.7 V vs. 12.5–13.8 V) | No functional difference in circuit design; interchangeable in layout and BOM | Select when sourcing from STMicroelectronics or preferred distributor stock; same PCB footprint and electrical behavior |
| 1.5KE13CA | Larger DO-201 package (axial leaded), higher RθJA (~50 °C/W), same VWM/VC but lower surge repetition capability due to thermal mass limitations | Not suitable for high-density SMT layouts; requires through-hole assembly and additional board space | Choose only for legacy through-hole designs or where manual repair access is prioritized over miniaturization |
Compared with SMBJ13CA and 1.5KE13CA, P6SMB13CA-E3/52 offers optimal balance of compact SMB packaging, industry-standard surge ratings, and RoHS-compliant commercial-grade construction - making it the preferred choice for new SMT-based industrial and automotive designs requiring high-volume manufacturability.

FAQ
What does the "CA" suffix mean in P6SMB13CA-E3/52?
The "CA" suffix in P6SMB13CA-E3/52 indicates a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB13A), it has no polarity marking and functions identically regardless of applied voltage polarity, simplifying layout for AC-coupled or floating signal paths.
Is P6SMB13CA-E3/52 AEC-Q101 qualified?
P6SMB13CA-E3/52 itself is the commercial-grade RoHS-compliant variant. However, Vishay offers AEC-Q101 qualified versions under ordering codes such as P6SMB13CAHE3_B/H (with "HE3" and "_B" suffixes). These undergo extended stress testing for automotive use, while P6SMB13CA-E3/52 meets industrial-grade reliability standards and is widely deployed in non-automotive applications requiring high surge immunity.
What is the maximum clamping voltage of P6SMB13CA-E3/52 under surge conditions?
The maximum clamping voltage (VC) of P6SMB13CA-E3/52 is 18.2 V, measured at its rated peak pulse current (IPPM) of 33.0 A using the standard 10/1000 μs waveform. This value represents the highest voltage the protected circuit will experience during a worst-case transient event, ensuring compatibility with 12 V and 15 V rail systems.
Can P6SMB13CA-E3/52 replace P6SMB13A in an existing design?
Yes, P6SMB13CA-E3/52 can replace P6SMB13A only if the circuit requires bidirectional protection - for example, on differential or AC-coupled lines. However, P6SMB13A is unidirectional and includes a cathode band marking; substituting without verifying polarity and clamping symmetry may compromise protection. Always validate layout and signal path polarity before interchange.
What is the thermal resistance of P6SMB13CA-E3/52, and how does it affect layout?
P6SMB13CA-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value guides PCB copper area allocation: reducing pad size increases thermal impedance, risking junction overheating during repetitive surges. Maintain minimum recommended pad layout to ensure reliable 600 W pulse handling without derating.
