Product details
Overview
P6SMB13CA-M3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 13 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 33.0 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) capability under 10/1000 μs waveform. It protects signal lines and power rails in automotive sensor interfaces, industrial I/O modules, and telecom line cards against ESD and inductive switching transients.
For engineers reviewing the P6SMB13CA-M3/5B datasheet, P6SMB13CA-M3/5B pinout, P6SMB13CA-M3/5B application, or P6SMB13CA-M3/5B equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, AEC-Q101 qualification status, and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker testing.
Technical Context
The P6SMB13CA-M3/5B operates as a symmetric bidirectional TVS, exhibiting identical breakdown (VBR min = 12.4 V, max = 13.7 V at IT = 1.0 mA) and clamping characteristics in both polarities. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing sub-microsecond transients on high-speed data lines.
Thermal performance is defined by RθJA = 100 °C/W (typical, on 0.2" × 0.2" copper pads) and maximum junction temperature of +150 °C. Derating above TA = 25 °C follows Fig. 2 in the datasheet, with 100% power rating at 25 °C dropping to ~50% at 75 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 11.1 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 12.4 V to 13.7 V at 1.0 mA - Voltage at which device transitions into avalanche conduction; tight tolerance ensures predictable turn-on. |
| VC (Clamping) | 18.2 V at IPPM = 33.0 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream ICs. |
| PPPM | 600 W - Peak transient energy absorption capacity; supports repetitive surges up to 0.01% duty cycle. |
| ID (Leakage) | 5.0 μA max at VWM - Low reverse leakage preserves signal integrity and minimizes standby power loss in battery-powered systems. |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures without forced cooling. |
| Package | SMB (DO-214AA) - Surface-mount footprint compatible with automated placement; meets UL 94 V-0 flammability standard. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); cathode/anode terminals are symmetrical and non-polarized.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM (11.1 V), VC = 21.5 V at IPPM = 27.8 A; lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 due to reduced power handling. | Select when board space is constrained and surge threat level is ≤Level 3; verify thermal margin with RθJA = 140 °C/W. |
| 1.5KE13CA | Same VWM/VC specs but axial-leaded DO-201 package; higher IPPM (43.3 A); same 600 W rating but slower response due to lead inductance. | Not suitable for high-frequency or high-density SMT designs; requires through-hole assembly and larger keep-out area. | Choose only for legacy through-hole systems or prototyping where rework flexibility outweighs performance trade-offs. |
Compared with SMAJ13CA and 1.5KE13CA, the P6SMB13CA-M3/5B delivers optimal balance of SMT manufacturability, 600 W surge robustness, and low-profile SMB packaging-enabling compact, automotive-grade protection without sacrificing clamping performance or thermal reliability.

FAQ
What is the clamping voltage of the P6SMB13CA-M3/5B under a 10/1000 μs surge?
The P6SMB13CA-M3/5B clamps to a maximum of 18.2 V when subjected to its rated peak pulse current of 33.0 A under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB13CA-M3/5B maintains this clamping performance across its full operating temperature range from −65 °C to +150 °C.
Is the P6SMB13CA-M3/5B suitable for automotive applications?
Yes-the base P6SMB13CA-M3/5B is halogen-free and RoHS-compliant, and the AEC-Q101 qualified variant (P6SMB13CAHM3_B) is explicitly certified for automotive use. While the M3/5B suffix itself denotes commercial-grade halogen-free construction, it shares identical electrical and thermal specifications with the HM3_B version and is widely deployed in automotive body electronics, infotainment power supplies, and sensor signal conditioning where AEC-Q101 is not mandated. The P6SMB13CA-M3/5B meets MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
How does the bidirectional nature of the P6SMB13CA-M3/5B affect its layout?
The P6SMB13CA-M3/5B has no polarity marking and exhibits symmetric electrical behavior in both directions, eliminating orientation constraints during PCB placement. This simplifies layout for AC-coupled interfaces like RS-485, CAN FD, or audio lines, where traditional unidirectional TVS diodes would require careful anode/cathode alignment. The P6SMB13CA-M3/5B can be placed across any two nodes without regard to voltage polarity, reducing assembly errors and supporting automated optical inspection (AOI) with fewer orientation checks.
What is the maximum steady-state power dissipation of the P6SMB13CA-M3/5B?
The P6SMB13CA-M3/5B has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at TA = 50 °C. In real-world PCB layouts using the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, derating applies above 25 °C ambient per Figure 2 in the datasheet. At 75 °C ambient, the usable PD drops to approximately 2.5 W. This thermal limit governs continuous leakage current handling and must be considered alongside transient surge duty cycle in power supply rail protection designs using the P6SMB13CA-M3/5B.
Does the P6SMB13CA-M3/5B meet IEC 61000-4-2 and IEC 61000-4-5 standards?
The P6SMB13CA-M3/5B is engineered to protect circuits against threats defined in IEC 61000-4-2 (ESD ±8 kV contact, ±15 kV air) and IEC 61000-4-5 (surge 1 kV–4 kV line-to-ground, depending on coupling network and layout). Its 600 W peak pulse power and 18.2 V clamping voltage enable compliance when implemented with proper PCB layout-including minimum 5.0 mm × 5.0 mm copper pads, short traces, and grounding strategy per Vishay Application Note AN8001. The P6SMB13CA-M3/5B itself is not certified to these standards, but functions as a key enabling component in compliant system designs.
