Product details
Overview
P6SMB13AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 13 V breakdown voltage (VBR = 12.4–13.7 V at IT = 1.0 mA), 11.1 V stand-off voltage (VWM), and 18.2 V maximum clamping voltage (VC) at 33.0 A peak pulse current (IPPM). It delivers 600 W peak pulse power (10/1000 μs waveform) and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB13AHE3_A/H datasheet, P6SMB13AHE3_A/H pinout, P6SMB13AHE3_A/H application, or P6SMB13AHE3_A/H equivalent, this device serves as a robust, low-profile overvoltage clamp for DC power rails and signal lines in automotive ECUs, industrial sensor interfaces, and telecom front-end circuits where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.4), and MSL Level 1 reliability are required.
Technical Context
The P6SMB13AHE3_A/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<5.0 μA at VWM), while the SMB package enables automated placement and meets UL 94 V-0 flammability rating.
It features a low incremental surge resistance (Rdyn ≈ 0.21 Ω derived from ΔVC/ΔIPPM) and thermal resistance of 100 °C/W (junction-to-ambient), enabling reliable operation up to TJ = 150 °C. The cathode band marking confirms polarity, critical for correct orientation in series-connected protection schemes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche onset window for repeatable clamping behavior |
| VWM | 11.1 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 18.2 V at 33.0 A - clamped voltage seen by protected circuit during 10/1000 μs transient |
| PPPM | 600 W - peak transient energy absorption capability under standardized surge waveform |
| IFSM | 100 A - surge current handling for 8.3 ms half-sine wave, supporting inductive load switching events |
| TJ max. | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| Package | SMB (DO-214AA) - 0.220" × 0.130" footprint with matte tin-plated leads, J-STD-002 solderable |

IC Role / Device Role / Timing Role: Unidirectional TVS placed between input terminal and optocoupler anode, clamping reverse transients before isolation barrier. Use Value: Absorbs 33 A pulses without failure, maintaining input logic state fidelity and eliminating false triggering due to voltage spikes. |
| Telecom Power Supply Front-End | Consumer Appliance Motor Driver Interface |
Use Scenario: Shielding AC/DC adapter output and PoE interface circuits from lightning-induced surges (IEC 61000-4-5) and hot-swap transients. IC Role / Device Role / Timing Role: Secondary-level TVS after primary MOV, providing precise low-voltage clamping for downstream DC-DC converters. Use Value: Clamps to 18.2 V within <1 ns, protecting 20 V-rated buck controllers and avoiding overvoltage shutdown. |
Use Scenario: Suppressing back-EMF from brushed DC motors in washing machines and HVAC blowers connected to MCU GPIOs and driver ICs. IC Role / Device Role / Timing Role: Localized TVS across motor terminals and H-bridge high-side FET source-drain, referenced to system ground. Use Value: Handles repetitive 100 A surge currents (8.3 ms) from motor commutation, extending MOSFET lifetime and reducing EMI radiation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5B | Same VBR range (12.4–13.7 V), but SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-power or space-constrained designs; not AEC-Q101 qualified | Select when board area is critical and automotive qualification is unnecessary |
| 1.5SMC13A | Same electrical specs but SMC (DO-214AB) package (larger, 7.11 mm × 6.22 mm), higher IPPM (35.3 A) | Better thermal dissipation for high-duty-cycle surges; incompatible with SMB land pattern | Choose for industrial systems requiring >600 W margin or extended thermal endurance |
Compared with SMAJ13A-E3/5B and 1.5SMC13A, the P6SMB13AHE3_A/H uniquely balances AEC-Q101 compliance, SMB footprint compatibility, and 600 W surge capacity-making it the preferred choice for automotive and high-reliability industrial PCBs where qualification, layout reuse, and standardized assembly are mandatory.

FAQ
What is the exact breakdown voltage range for P6SMB13AHE3_A/H?
The P6SMB13AHE3_A/H has a guaranteed breakdown voltage (VBR) range of 12.4 V to 13.7 V at test current IT = 1.0 mA, measured per ANSI/IEEE C62.35. This tight ±5% tolerance ensures consistent clamping performance across production lots and supports precise overvoltage margin design in 12 V systems.
Is P6SMB13AHE3_A/H suitable for automotive applications?
Yes, P6SMB13AHE3_A/H is AEC-Q101 qualified and designated with the "HE3" suffix indicating RoHS-compliant and automotive-grade construction. It passes stress tests including temperature cycling, highly accelerated stress testing (HAST), and mechanical shock-making it approved for under-hood and cabin ECU use per ISO/TS 16949 requirements.
What is the maximum clamping voltage of P6SMB13AHE3_A/H under surge conditions?
The P6SMB13AHE3_A/H exhibits a maximum clamping voltage (VC) of 18.2 V at peak pulse current IPPM = 33.0 A, tested with a 10/1000 μs waveform. This value represents the worst-case voltage imposed on the protected circuit during standardized surge events and is critical for verifying safe operating margins of downstream ICs rated for ≤20 V absolute maximum.
Does P6SMB13AHE3_A/H have a bidirectional variant?
No, P6SMB13AHE3_A/H is strictly unidirectional. Bidirectional variants in the same series use the "CA" suffix (e.g., P6SMB13CA). The "A" suffix denotes unidirectional configuration with cathode band marking; using a unidirectional part in bidirectional signal paths risks catastrophic failure during negative transients.
What is the thermal resistance of P6SMB13AHE3_A/H and how does it affect layout?
P6SMB13AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. To maintain TJ ≤ 150 °C under 600 W pulses, designers must ensure adequate copper area and avoid thermal bottlenecks-reducing pad size below specification increases RθJA and risks thermal runaway during repetitive surges.
