Product details
Overview
P6SMB13AHE3/52 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 1.0 mA), 11.1 V stand-off voltage (VWM), 18.2 V maximum clamping voltage (VC) at 33.0 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 automotive and industrial systems.
For engineers reviewing the P6SMB13AHE3/52 datasheet, P6SMB13AHE3/52 pinout, P6SMB13AHE3/52 application, or P6SMB13AHE3/52 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), polarity marking (cathode band), and real-world protection use cases - all confirmed from Vishay's official P6SMB Series specification document (Rev. 09-Jan-2024, Doc. #88370).
Technical Context
The P6SMB13AHE3/52 operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its specified VBR range (12.4–13.7 V). Its low incremental surge resistance and fast response time enable effective suppression of ESD and inductive switching transients without latch-up or degradation under repetitive 0.01% duty cycle conditions.
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it meets J-STD-020 MSL Level 1, supports peak forward surge current up to 100 A (8.3 ms half-sine), and maintains stable operation across -65 °C to +150 °C junction temperature range - validated per AEC-Q101 for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche initiation threshold for repeatable transient clamping |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 μA |
| VC @ IPPM | 18.2 V at 33.0 A - clamped voltage during 600 W 10/1000 μs transient, limiting stress on downstream components |
| PPPM | 600 W - peak pulse power handling capability under standardized surge waveform, critical for IEC 61000-4-5 compliance margin |
| RθJA | 100 °C/W - junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads, guiding thermal layout design |
| TJ max. | +150 °C - maximum allowable junction temperature, enabling use in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - certified for automotive applications; ordering code suffix HE3 denotes RoHS-compliant + AEC-Q101 qualification |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, UL 94 V-0 molding compound. Cathode indicated by band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal (unidirectional) | Connected to lower-potential side of protected line; conducts during forward surge or bias |
| Cathode | Reverse-biased clamping terminal | Marked with band; connected to higher-potential side; avalanches to clamp transients above VWM |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables robust protection against high-energy surges like ISO 7637-2 Pulse 5a without derating in compact SMB footprint |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive electronics including engine control units and ADAS sensor interfaces requiring long-term reliability |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage stress on protected ICs - e.g., keeps 3.3 V or 5 V logic rails within safe operating area during transients |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free SMT assembly without moisture sensitivity concerns or pre-bake requirements |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage (<5 μA at VWM) over temperature and lifetime |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|

Use Scenario: Protecting -48 V DC feeder inputs in 4G/5G remote radio units from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: TVS array element rated for bidirectional capability (via companion CA variant) but used here in unidirectional configuration for negative rail clamping. Use Value: Handles 600 W pulses without failure, sustaining system uptime during Category C2/C3 surge events per IEC 61000-4-5. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same VBR (12.4–13.7 V), identical SMB package, but rated for 400 W PPPM (vs. 600 W) | Limited to lower-energy transients; not recommended for automotive load dump or telecom feeder protection | Select P6SMB13AHE3/52 when 600 W surge handling is required; SMAJ13A suits cost-sensitive consumer applications with milder threat profiles |
| 1.5SMC13A | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VBR range, but 2.5× footprint area | Used where board space permits and higher single-event energy absorption is mandatory (e.g., industrial motor drives) | Choose P6SMB13AHE3/52 for space-constrained automotive PCBs needing AEC-Q101; 1.5SMC13A fits when thermal margin and layout area allow larger package |
Compared with SMAJ13A and 1.5SMC13A, the P6SMB13AHE3/52 uniquely balances 600 W surge capability, AEC-Q101 qualification, and SMB footprint - making it optimal for automotive and industrial designs where reliability, size, and standardized test compliance are jointly critical.

FAQ
What is the clamping voltage of the P6SMB13AHE3/52 at its rated peak pulse current?
The P6SMB13AHE3/52 has a maximum clamping voltage (VC) of 18.2 V at 33.0 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per Vishay's official specification (Doc. #88370, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The P6SMB13AHE3/52 maintains this clamping performance across its full operating temperature range.
Is the P6SMB13AHE3/52 qualified for automotive applications?
Yes, the P6SMB13AHE3/52 is AEC-Q101 qualified, as confirmed by its "HE3" suffix - indicating RoHS compliance and automotive-grade reliability testing. It is rated for junction temperatures from -65 °C to +150 °C and validated for repetitive surge endurance, making it suitable for engine control units, ADAS sensors, and body electronics. The P6SMB13AHE3/52 meets the stress requirements defined in the AEC-Q101 standard for transient voltage suppressors.
What does the "HE3" suffix mean in P6SMB13AHE3/52?
The "HE3" suffix in P6SMB13AHE3/52 indicates RoHS-compliant construction and AEC-Q101 qualification - distinguishing it from commercial-grade variants (e.g., E3 or M3). The "H" denotes automotive qualification, "E3" confirms lead-free matte tin plating and JESD201 Class 2 whisker resistance. This suffix ensures traceability to Vishay's automotive product release process and is documented in the P6SMB Series datasheet (Rev. 09-Jan-2024).
How does the P6SMB13AHE3/52 differ from bidirectional TVS diodes like P6SMB13CA?
The P6SMB13AHE3/52 is unidirectional, with polarity marked by a cathode band and intended for DC line protection where reverse conduction must be blocked. In contrast, P6SMB13CA is bidirectional, symmetric in both directions, and used for AC or floating signal lines. Their VBR, VWM, and VC values differ accordingly - the P6SMB13AHE3/52 has VWM = 11.1 V and VBR = 12.4–13.7 V, while P6SMB13CA specifies VWM = 11.1 V for each polarity and same VBR range.
What is the thermal resistance of the P6SMB13AHE3/52, and how does it affect PCB layout?
The P6SMB13AHE3/52 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 - as defined in Vishay's datasheet. This value guides minimum pad sizing and copper pour design: reducing RθJA requires increasing pad area or adding thermal vias. Exceeding TJ max. (+150 °C) risks parametric shift or failure, so layout must ensure adequate heat dissipation during repetitive surge events.
