Product details
Overview
P6SMB13A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 13 V breakdown voltage (VBR = 12.4–13.7 V at 1 mA), 11.1 V stand-off voltage (VWM), 18.2 V maximum clamping voltage (VC) at 33 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB13A-E3/5B datasheet, P6SMB13A-E3/5B pinout, P6SMB13A-E3/5B application, or P6SMB13A-E3/5B equivalent, this device is selected for robust ESD and surge protection where low clamping voltage, fast response (<1 ns), and AEC-Q101 qualification readiness (via HE3 suffix variants) are critical in automotive and industrial control designs.
Technical Context
The P6SMB13A-E3/5B operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage performance (≤5 μA at VWM) and low incremental surge resistance, enabling precise clamping under repetitive 10/1000 μs transients at 0.01% duty cycle.
Thermally, it exhibits RθJA = 100 °C/W and RθJL = 20 °C/W, supporting reliable operation up to TJ = 150 °C. The cathode-band-marked SMB package provides mechanical robustness, UL 94 V-0 flammability compliance, and compatibility with automated SMT placement and J-STD-002 soldering standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 12.4–13.7 V at 1 mA - defines precise avalanche initiation point for repeatable clamping behavior |
| Stand-off Voltage VWM | 11.1 V - maximum continuous reverse voltage before significant leakage; sets operating margin below VBR |
| Clamping Voltage VC | 18.2 V at 33 A (10/1000 μs) - limits transient voltage seen by protected circuitry during surge events |
| Peak Pulse Power PPPM | 600 W - sustains high-energy surges without failure, validated per IEC 61000-4-5 Level 4 requirements |
| Peak Pulse Current IPPM | 33 A - maximum non-repetitive surge current the device can safely divert |
| Reverse Leakage ID | ≤5 μA at VWM - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Operating Temperature | −65 °C to +150 °C - supports deployment in under-hood automotive and industrial environments |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-indicated by band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals matte tin-plated, J-STD-002 solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal (cathode-banded end is opposite) | Connected to lower-potential side of protected line; enables unidirectional clamping from cathode to anode |
| Cathode | Avalanche conduction terminal (marked with band) | Connected to higher-potential side (e.g., VCC rail or signal line); conducts transient current to ground when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables protection against IEC 61000-4-5 combination wave surges up to 4 kV without derating |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage stress on downstream components during transient events |
| Glass-passivated junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure |
| MSL Level 1 (260 °C peak reflow) | Supports single-pass lead-free reflow assembly without moisture-related popcorning |
| RoHS-compliant, halogen-free option available | Meets environmental compliance requirements for global industrial and automotive supply chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same SMB package, identical VBR (12.4–13.7 V), but lower PPPM (400 W) and higher VC (21.5 V at 19.3 A) | Limited to lower-energy transients; not suitable for IEC 61000-4-5 Level 4 compliance | Select SMAJ13A only for cost-sensitive consumer applications with sub-400 W surge requirements |
| 1.5SMC13A | Larger SMC (DO-214AB) package, same electrical specs, higher thermal mass (RθJA = 50 °C/W), 1500 W PPPM rating | Requires PCB layout change; suited for high-reliability industrial power supplies needing extended surge endurance | Choose 1.5SMC13A when board space allows and system-level surge testing exceeds 600 W validation |
Compared with SMAJ13A and 1.5SMC13A, the P6SMB13A-E3/5B delivers optimal balance of compact SMB footprint, 600 W surge capability, and 18.2 V clamping - making it the preferred choice for space-constrained automotive and industrial modules requiring certified transient immunity without package redesign.

FAQ
What is the maximum clamping voltage of the P6SMB13A-E3/5B under a 10/1000 μs surge?
The P6SMB13A-E3/5B has a maximum clamping voltage (VC) of 18.2 V when subjected to a 33 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions defined in the Vishay datasheet (Document Number: 88370), and reflects the actual voltage imposed on protected circuitry during worst-case surge events - critical for validating safe operating margins of downstream ICs and MOSFETs.
Is the P6SMB13A-E3/5B RoHS-compliant and halogen-free?
Yes, the P6SMB13A-E3/5B carries the "E3" suffix, indicating full RoHS compliance per EU Directive 2011/65/EU. It is not halogen-free; for halogen-free and RoHS-compliant versions, the "M3" suffix (e.g., P6SMB13A-M3/5B) must be specified. Both E3 and M3 variants meet JESD 201 Class 2 whisker resistance and J-STD-002 solderability standards.
Does the P6SMB13A-E3/5B have AEC-Q101 qualification?
The base P6SMB13A-E3/5B is commercial-grade and not AEC-Q101 qualified. However, Vishay offers AEC-Q101 qualified variants under the "HE3" suffix (e.g., P6SMB13AHE3_B), which include additional automotive-grade screening and traceability. The "_B" revision code denotes AEC-Q101 qualification for P6SMB6.8A through P6SMB220A devices, including P6SMB13A.
What is the thermal resistance from junction to ambient for the P6SMB13A-E3/5B?
The P6SMB13A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes still air convection and is essential for calculating maximum allowable power dissipation at elevated ambient temperatures - for example, limiting continuous power to ≤2.5 W at TA = 75 °C to maintain TJ ≤ 150 °C.
How does the P6SMB13A-E3/5B differ from bidirectional variants like P6SMB13CA?
The P6SMB13A-E3/5B is unidirectional, with polarity marked by a cathode band and intended for DC line protection (e.g., VCC-to-ground). In contrast, P6SMB13CA is bidirectional, symmetric in both directions, and used for AC signal or data line protection (e.g., RS-485, USB D+/D−). Their VBR, VWM, and VC values differ: P6SMB13CA has VWM = 11.1 V (same), but VBR = 12.4–13.7 V in both directions and VC = 21.2 V at 28.3 A - reflecting different clamping behavior and surge distribution.
