Product details
Overview
P6SMB62AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 53.0 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1 mA test current, 85.0 V maximum clamping voltage (VC) at 7.1 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive-grade ECU protection, industrial sensor interfaces, and DC power rail surge suppression.
For engineers reviewing the P6SMB62AHE3_B/I datasheet, P6SMB62AHE3_B/I pinout, P6SMB62AHE3_B/I application, or P6SMB62AHE3_B/I equivalent, key selection considerations include its AEC-Q101 qualification, SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates as a fast-acting shunt protector, responding to transient overvoltages by entering avalanche breakdown before downstream components are stressed. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low incremental surge resistance, enabling consistent clamping performance across repetitive 10/1000 μs pulses at 0.01% duty cycle.
The device is rated for -65 °C to +150 °C operating junction temperature, meets J-STD-020 MSL Level 1 (peak reflow 260 °C), and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards - confirming suitability for high-reliability automated SMT assembly in automotive and industrial environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-E3/5B | Same SMB package, 60 V VWM, 66.7–73.7 V VBR, 96.8 V VC at 6.2 A - higher clamping voltage, no AEC-Q101 qualification. | Commercial-grade only; not validated for automotive temperature cycling or humidity testing. | Select when AEC-Q101 is unnecessary and higher clamping margin is acceptable for less sensitive loads. |
| 1.5SMC62A | Same 62 V nominal rating, but in larger SMC (DO-214AB) package (2.54 mm height vs. SMB's 2.2 mm); RθJA ≈ 70 °C/W - better thermal performance but requires more board area. | Preferred where higher power derating or extended pulse handling is needed beyond 600 W single-shot. | Choose when thermal management is critical and PCB space allows larger footprint; not drop-in compatible due to different pad layout. |

FAQ
What is the clamping voltage of the P6SMB62AHE3_B/I under a 10/1000 μs transient?
The P6SMB62AHE3_B/I has a maximum clamping voltage (VC) of 85.0 V at a peak pulse current (IPPM) of 7.1 A with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P6SMB62AHE3_B/I qualified for automotive applications?
Yes, the P6SMB62AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3_B", where "_B" denotes AEC-Q101 qualification for the P6SMB6.8A to P6SMB220A voltage range. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling - validating its use in engine control units, body electronics, and ADAS sensor modules.
What does the "HE3_B/I" suffix mean in P6SMB62AHE3_B/I?
In P6SMB62AHE3_B/I, "HE3" indicates RoHS-compliant, AEC-Q101-qualified construction; "_B" specifies AEC-Q101 qualification level for this voltage range; and "/I" denotes packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This full suffix confirms both automotive-grade reliability and high-volume SMT-ready delivery format - distinct from commercial-grade "E3" or halogen-free "HM3" variants.
How does the P6SMB62AHE3_B/I compare to bidirectional TVS diodes like P6SMB62CA?
The P6SMB62AHE3_B/I is unidirectional, meaning it protects against positive transients only (cathode to anode), with a defined polarity band. In contrast, P6SMB62CA is bidirectional and symmetrical - suitable for AC lines or differential signals. The unidirectional P6SMB62AHE3_B/I offers lower leakage (<1.0 μA at 53.0 V) and tighter VBR tolerance than its bidirectional counterpart, making it preferred for DC power rail protection where polarity is fixed and leakage sensitivity matters.
What is the thermal resistance and recommended PCB layout for the P6SMB62AHE3_B/I?
The P6SMB62AHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Vishay specifies this pad layout in the datasheet (Document Number 88370, page 5) - using smaller pads increases thermal impedance and risks exceeding TJ max. of +150 °C during repetitive surges.
