Product details
Overview
P6SMB62CAHE3/52 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 53.0 V standoff voltage (VWM), 62.0 V minimum breakdown voltage (VBR), 85.0 V maximum clamping voltage (VC) at 7.1 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 industrial and automotive electronics.
For engineers reviewing the P6SMB62CAHE3/52 datasheet, P6SMB62CAHE3/52 pinout, P6SMB62CAHE3/52 application, or P6SMB62CAHE3/52 equivalent, this device is selected for robust ESD and surge protection where bidirectional clamping, AEC-Q101 qualification, and SMB (DO-214AA) package compatibility are required in space-constrained PCB layouts.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping performance without polarity dependency. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), while low incremental surge resistance supports effective energy diversion during transient events.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its thermal resistance (RθJA = 100 °C/W) reflects standard SMB pad layout assumptions (0.2" × 0.2" copper pads), and it is qualified to AEC-Q101 for automotive under-hood and infotainment applications.
Key Specifications

| VWM | 53.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin below breakdown. |
| VBR (min) | 58.9 V - Minimum voltage at which device enters avalanche conduction at 1.0 mA test current; ensures reliable turn-on threshold. |
| VC @ IPPM | 85.0 V - Clamped voltage at 7.1 A peak pulse current; determines maximum stress imposed on protected circuitry. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; defines transient energy absorption capability. |

IC Role / Device Role / Timing Role: Primary transient suppression element on 24 V DC input lines, positioned before optocoupler or Schmitt-trigger input stage. Use Value: Limits transient voltage to ≤85 V during 1 kV/500 A surge events (IEC 61000-4-5, 2 Ω source impedance), enabling reliable operation without false triggering or component failure. |
| Telecom Power Rail Protection | Consumer Appliance Motor Control Board |
|
Use Scenario: Guarding 48 V PoE-powered Ethernet switch ports and base station RF front-end supplies against lightning-induced surges and AC line coupling. IC Role / Device Role / Timing Role: Secondary-level TVS on DC-DC converter input rails, coordinated with primary GDT or MOV stages for staged energy handling. Use Value: Clamps fast-rising transients (<1 ns rise time) to safe levels within 10/1000 μs waveform envelope, preserving isolation barrier integrity and preventing secondary-side regulator latch-up. |
Use Scenario: Shielding microcontroller GPIOs and gate drivers on washing machine or HVAC control boards from brush-commutator noise and relay bounce. IC Role / Device Role / Timing Role: Localized TVS at motor driver IC outputs and feedback sensing nodes to suppress commutation spikes up to 600 V. Use Value: Enables compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity requirements while maintaining <100 ns response time to prevent MCU reset or ADC corruption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64CA | Same SMB package, 64 V VBR min, 100 V VC @ 6.1 A, 400 W PPPM; lower power rating and higher clamping voltage. | Less suitable for high-energy surges (e.g., ISO 7637-2 Pulse 5a); better for cost-sensitive consumer designs with lower threat profiles. | Select SMAJ64CA only if system-level testing confirms 100 V clamping is acceptable and peak surge energy remains below 400 W capability. |
| SMCJ64CA | Same VBR/VC range but in larger SMC (DO-214AB) package; 1500 W PPPM, 23.3 A IPPM, RθJA = 35 °C/W. | Requires larger PCB area and higher thermal mass; preferred for high-repetition-rate surges or elevated ambient temperatures (>85 °C). | Choose SMCJ64CA when board layout allows SMC footprint and thermal management supports higher power dissipation without derating. |
Compared with SMAJ64CA and SMCJ64CA, P6SMB62CAHE3/52 delivers optimal balance of 600 W surge capacity, SMB footprint efficiency, and AEC-Q101 qualification - making it the preferred choice for automotive and industrial applications requiring validated reliability in compact form factors.

FAQ
What is the standoff voltage (VWM) of P6SMB62CAHE3/52?
The standoff voltage of P6SMB62CAHE3/52 is 53.0 V. This value represents the maximum continuous reverse voltage the device can withstand without entering avalanche conduction. It ensures compatibility with 48 V nominal systems and provides sufficient margin below the 58.9 V minimum breakdown voltage. The P6SMB62CAHE3/52 maintains leakage current below 1.0 μA at this voltage, supporting low-power standby operation in sensitive circuits.
Is P6SMB62CAHE3/52 bidirectional or unidirectional?
P6SMB62CAHE3/52 is a bidirectional TVS diode, indicated by the "CA" suffix in its part number. It provides symmetrical clamping in both directions, eliminating the need for polarity-aware placement on PCBs. Unlike unidirectional variants (e.g., P6SMB62A), the P6SMB62CAHE3/52 has no cathode band marking and delivers identical VBR, VC, and IPPM characteristics regardless of voltage polarity applied across its terminals.
Does P6SMB62CAHE3/52 meet AEC-Q101 qualification?
Yes, P6SMB62CAHE3/52 is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and surge endurance - validating suitability for automotive under-hood and infotainment applications. The P6SMB62CAHE3/52 is rated for operation from −65 °C to +150 °C junction temperature and complies with MSL Level 1 handling requirements.
What is the maximum clamping voltage (VC) of P6SMB62CAHE3/52 at peak pulse current?
The maximum clamping voltage of P6SMB62CAHE3/52 is 85.0 V at 7.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events. The low clamping ratio (VC/VBR ≈ 1.44) of the P6SMB62CAHE3/52 helps preserve margin for downstream 3.3 V, 5 V, or 24 V logic and interface ICs during surge conditions.
What package type does P6SMB62CAHE3/52 use?
P6SMB62CAHE3/52 uses the SMB (DO-214AA) surface-mount package, measuring 0.220" × 0.130" with a 0.060" lead pitch. This low-profile outline supports automated pick-and-place assembly and standard IR reflow profiles. The P6SMB62CAHE3/52's SMB footprint enables high-density PCB layouts while maintaining thermal performance via recommended 0.2" × 0.2" copper pads per terminal, yielding RθJA = 100 °C/W.
