Product details
Overview
P6SMB15AHE3_A/I 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 12.8 V stand-off voltage (VWM), 14.3–15.8 V breakdown voltage (VBR) at 1 mA test current, 21.2 V maximum clamping voltage (VC) at 28.3 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 power supplies.
For engineers reviewing the P6SMB15AHE3_A/I datasheet, P6SMB15AHE3_A/I pinout, P6SMB15AHE3_A/I application, or P6SMB15AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below its 12.8 V stand-off voltage and rapidly transitions to low-impedance conduction above its 14.3–15.8 V breakdown threshold. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD and inductive switching spikes.
The device is rated for 600 W peak pulse power (10/1000 μs), supports 100 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits a +0.084 %/°C temperature coefficient of VBR. Its thermal resistance (RθJA = 100 °C/W) and MSL Level 1 moisture sensitivity support reflow-compatible assembly without preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 12.8 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping onset |
| VBR (Breakdown) | 14.3–15.8 V at 1 mA - Confirmed breakdown range ensuring reliable turn-on during transients |
| VC (Clamping) | 21.2 V at 28.3 A - Peak voltage seen by protected circuit under 600 W transient; limits stress on downstream components |

| Low profile SMB package | 0.220" × 0.130" footprint supports high-density routing and automated pick-and-place with JEDEC-standard tape-and-reel (I = 3200 pcs/reel) |
| Fast response time (<1.0 ns) | Clamps transients before sensitive CMOS inputs or gate drivers experience destructive overvoltage |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp positive-going spikes up to ±100 V. Use Value: Limits voltage seen by LDOs and microcontrollers to ≤21.2 V during 600 W surges, preventing latch-up or gate oxide damage. |
Use Scenario: Shielding analog output lines of pressure/temperature sensors from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance clamping element on 4–20 mA or 0–5 V signal paths to preserve signal integrity. Use Value: Sub-1 ns response prevents >12.8 V transients from propagating to ADC front-ends, maintaining measurement accuracy. |
| Consumer Power Adapter Input Stage | Telecom DC Feeder Line Protection |
Use Scenario: Safeguarding AC/DC adapter primary-side controllers from mains-borne surges and switching noise. IC Role / Device Role / Timing Role: Standoff-rated TVS across bulk capacitor input to absorb repetitive 10/1000 μs line transients. Use Value: 600 W rating sustains repeated surge events without degradation, extending adapter field life beyond 5 years. |
Use Scenario: Protecting PoE-powered equipment (e.g., IP cameras) from induced surges on 48 V DC feeder lines. IC Role / Device Role / Timing Role: Unidirectional suppressor on DC input rail referenced to chassis ground to handle differential-mode surges. Use Value: 21.2 V clamping ensures powered devices remain operational during 1 kV/0.5 J surges per IEC 61000-4-5. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/5B | Same VWM/VBR/VC specs but SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower ambient or pulsed-duty use due to reduced thermal mass; not AEC-Q101 qualified | Select when board space is constrained and automotive qualification is unnecessary |
| 1.5SMC15A | Same electrical specs but SMC (DO-214AB) package - larger footprint, lower RθJA = 75 °C/W, same AEC-Q101 option available | Better thermal performance for high-repetition surges; requires larger PCB area and different stencil design | Select when sustained surge duty cycle exceeds 0.01% or junction temperature margin is critical |
Compared with SMAJ15A-E3/5B, P6SMB15AHE3_A/I offers superior thermal reliability and automotive qualification in an industry-standard SMB footprint; versus 1.5SMC15A, it trades some thermal headroom for tighter layout integration while retaining AEC-Q101 compliance and tape-and-reel logistics compatibility.

FAQ
What is the polarity configuration of P6SMB15AHE3_A/I?
P6SMB15AHE3_A/I is a unidirectional TVS diode, with the cathode identified by a band on the SMB package body. This configuration allows clamping only of positive-going transients relative to ground, making it suitable for DC power rail protection where reverse voltage is not expected. The device does not conduct in reverse bias until breakdown occurs, ensuring minimal leakage under normal operation.
Does P6SMB15AHE3_A/I meet automotive qualification standards?
Yes, P6SMB15AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST), validating its suitability for under-hood and chassis-mounted automotive applications such as body control modules and power distribution units.
What is the maximum clamping voltage of P6SMB15AHE3_A/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB15AHE3_A/I is 21.2 V, measured at a peak pulse current (IPPM) of 28.3 A using the standardized 10/1000 μs waveform. This value represents the highest voltage imposed on the protected circuit during worst-case transient events and is critical for ensuring downstream ICs and MOSFETs remain within their absolute maximum ratings.
How does the SMB package of P6SMB15AHE3_A/I compare thermally to larger packages like SMC?
P6SMB15AHE3_A/I in the SMB (DO-214AA) package has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, compared to ~75 °C/W for the SMC (DO-214AB) variant. This means P6SMB15AHE3_A/I requires careful PCB layout - specifically 0.2" × 0.2" copper pads per terminal - to sustain repetitive 600 W pulses. It is optimized for single-event or low-duty-cycle protection rather than continuous high-power dissipation.
What is the meaning of the "_A/I" suffix in P6SMB15AHE3_A/I?
The "_A/I" suffix in P6SMB15AHE3_A/I indicates packaging format: "A" denotes the AEC-Q101 qualified version (HE3), and "I" specifies 13-inch diameter plastic tape-and-reel delivery containing 3200 units. This format supports high-volume SMT assembly and aligns with Vishay's ordering nomenclature for automotive-grade TVS diodes with extended reel quantities.
