Product details
Overview
P6SMB13CAHE3_A/I 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 breakdown voltage (VBR min/max = 12.4 V / 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 signal lines in automotive and industrial control systems.
For engineers reviewing the P6SMB13CAHE3_A/I datasheet, P6SMB13CAHE3_A/I pinout, P6SMB13CAHE3_A/I application, or P6SMB13CAHE3_A/I equivalent, this AEC-Q101-qualified, RoHS-compliant bidirectional TVS offers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and surge protection design.
Technical Context
The P6SMB13CAHE3_A/I operates as a symmetrical avalanche diode with identical forward and reverse conduction characteristics, enabling bidirectional transient suppression without polarity dependency. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the SMB (DO-214AA) package supports automated placement and meets UL 94 V-0 flammability rating.
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, with operating junction temperature range of –65 °C to +150 °C. The device sustains repetitive 10/1000 μs pulses at 0.01% duty cycle and complies with JESD201 Class 2 whisker resistance requirements.

Applications
| Automotive Sensor Signal 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 ISO 7637-2 transients. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt surge energy before reaching interface IC. Use Value: Maintains signal integrity under ±18 V transients while limiting clamped voltage to ≤18.2 V - preserving 5 V tolerant input stages of automotive MCUs. |
Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against inductive switching spikes from solenoids and relays. IC Role / Device Role / Timing Role: Primary transient suppressor on field-side input traces, coordinated with series current-limiting resistors and filtering capacitors. Use Value: Absorbs 600 W surge energy without degradation, enabling >100,000 surge cycles per IEC 61000-4-5 compliance testing. |
| Consumer Power Adapter ESD Protection | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in USB-C PD adapters and AC/DC wall adapters exposed to human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Fast-response TVS placed across output rails (e.g., 5 V, 9 V, 15 V) to clamp ESD-induced overshoot before reaching USB controller or PMIC. Use Value: Sub-1 ns response time prevents latch-up in downstream silicon; 11.1 V VWM ensures no conduction during normal 13 V nominal output regulation. |
Use Scenario: Protection of Ethernet PHY or RS-485 transceivers connected to unshielded outdoor cabling susceptible to lightning-induced surges. IC Role / Device Role / Timing Role: First-line defense in hybrid protection circuits - paired with GDTs or polymer PTCs for multi-stage coordination. Use Value: Symmetrical clamping ensures equal protection for differential pairs; 18.2 V VC aligns with 24 V rail tolerance limits in telecom infrastructure equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VBR (12.4–13.7 V) and VC (18.2 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients (IEC 61000-4-2 ESD only); unsuitable for IEC 61000-4-5 surge in industrial environments | Select when board space is constrained and surge energy is <400 W; verify thermal margin with RθJA = 140 °C/W |
| 1.5KE13CA | Higher PPPM (1500 W), axial-leaded TO-204AE (DO-201AE) package; larger size, manual assembly only | Used in legacy through-hole designs or high-energy AC line protection; incompatible with automated SMT processes | Choose for prototyping or repair where SMT compatibility is not required and surge energy exceeds 600 W |
Compared with SMAJ13CA and 1.5KE13CA, the P6SMB13CAHE3_A/I delivers optimal balance of 600 W surge handling, AEC-Q101 qualification, and SMB-packaged SMT manufacturability - making it the preferred choice for volume automotive and industrial PCB designs requiring validated reliability and process compatibility.

FAQ
What is the breakdown voltage tolerance of the P6SMB13CAHE3_A/I?
The P6SMB13CAHE3_A/I has a specified breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, representing a ±5.4% tolerance around the nominal 13 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, directly supporting compliance with IEC 61000-4-5 surge immunity requirements for protected circuits. The P6SMB13CAHE3_A/I maintains this specification under full AEC-Q101 qualification testing.
Is the P6SMB13CAHE3_A/I suitable for automotive applications?
Yes, the P6SMB13CAHE3_A/I is explicitly AEC-Q101 qualified and carries the "HE3" suffix denoting RoHS-compliant, automotive-grade construction. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification per AEC standards. The P6SMB13CAHE3_A/I is deployed in automotive body control modules, sensor front-ends, and infotainment power supplies where sustained reliability under thermal and electrical stress is non-negotiable.
What is the maximum clamping voltage of the P6SMB13CAHE3_A/I during a 10/1000 μs surge?
The P6SMB13CAHE3_A/I exhibits a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 33.0 A under the standardized 10/1000 μs double-exponential waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events - critical for ensuring compatibility with 5 V or 12 V logic interfaces downstream of the P6SMB13CAHE3_A/I.
Does the P6SMB13CAHE3_A/I require polarity-aware PCB layout?
No, the P6SMB13CAHE3_A/I is a bidirectional TVS diode with symmetrical terminal construction and no cathode marking - both leads are functionally identical. This eliminates orientation constraints during PCB layout and automated placement, reducing assembly errors and simplifying routing for differential or AC-coupled signal paths. The P6SMB13CAHE3_A/I's bidirectional behavior is confirmed in Vishay's P6SMB series documentation under "DEVICES FOR BIDIRECTION APPLICATIONS".
What is the thermal resistance of the P6SMB13CAHE3_A/I and how does it affect power dissipation?
The P6SMB13CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads, and junction-to-lead resistance (RθJL) of 20 °C/W. These values determine steady-state power derating: at 50 °C ambient, its continuous power dissipation (PD) is limited to 5.0 W. For transient events, the 600 W PPPM rating applies only for short-duration 10/1000 μs pulses at ≤0.01% duty cycle - the P6SMB13CAHE3_A/I's thermal design ensures no cumulative heating under repetitive surge conditions.
