Product details
Overview
P6SMB22AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, featuring 22 V standoff voltage (VWM = 18.8 V), 30.6 V clamping voltage at 19.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed for overvoltage protection of MOSFETs and signal lines in automotive sensor units.
For engineers reviewing the P6SMB22AHE3_A/H datasheet, P6SMB22AHE3_A/H pinout, P6SMB22AHE3_A/H application, or P6SMB22AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and 150 °C maximum junction temperature for under-hood automotive environments.
Technical Context
This TVS diode operates as a clamping device that enters avalanche breakdown when reverse voltage exceeds its 20.9–23.1 V breakdown range (VBR at 1 mA), limiting transient-induced voltage spikes to ≤30.6 V while absorbing up to 600 W of surge energy. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns).
Designed for automated SMT assembly, it uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability requirements. The cathode band denotes polarity, and thermal resistance is 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads.

|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in engine control units. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp transients before they reach sensitive input pins. Use Value: Limits induced voltage to ≤30.6 V during 10/1000 μs surges, preventing latch-up or gate oxide damage in downstream ASICs. |
Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers exposed to relay coil flyback and EFT bursts. IC Role / Device Role / Timing Role: Standoff-rated TVS connected across input terminals to shunt surge current away from optocoupler inputs. Use Value: Withstands repetitive 600 W pulses at 0.01% duty cycle, ensuring long-term reliability in factory automation environments. |
| Consumer Power Adapter Protection | Telecom Line Interface Protection |
|
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for USB-C PD chargers subjected to lightning-induced surges on DC output rails. IC Role / Device Role / Timing Role: Unidirectional clamping device between +VOUT and GND, triggered only during reverse overvoltage events. Use Value: Fast <1 ns response captures sub-microsecond transients, preserving regulation integrity of synchronous buck controllers. |
Use Scenario: Front-end protection of Ethernet PHY interfaces and DSL line drivers against induced surges from nearby power lines or electrostatic discharge. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. <100 pF at 0 V) placed inline with differential pairs to avoid signal integrity degradation. Use Value: Clamps common-mode surges to ≤30.6 V while maintaining <0.1 dB insertion loss up to 100 MHz due to SMB package geometry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-E3/52 | Same VWM (18.8 V), identical SMB package, but rated for 400 W PPPM (vs. 600 W) | Limited to lower-energy transients (e.g., IEC 61000-4-4 EFT); not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and higher surge margin |
| 1.5SMC22A | Higher package thermal resistance (RθJA = 125 °C/W), same 600 W rating, but DO-214AB (SMC) footprint | Requires PCB redesign due to larger 7.11 mm × 6.22 mm body vs. SMB's 4.57 mm × 3.94 mm | Choose only if existing design uses SMC footprint and needs identical electrical specs |
Compared with SMAJ22A-E3/52 and 1.5SMC22A, P6SMB22AHE3_A/H delivers superior surge margin (600 W), automotive qualification, and compact SMB layout - making it optimal for space-constrained, high-reliability automotive and industrial edge nodes.

FAQ
What is the clamping voltage of P6SMB22AHE3_A/H at its rated peak pulse current?
The P6SMB22AHE3_A/H has a maximum clamping voltage (VC) of 30.6 V at 19.6 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB22AHE3_A/H maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C).
Is P6SMB22AHE3_A/H qualified for automotive applications?
Yes, P6SMB22AHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's ordering information table (page 3). It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D. This makes P6SMB22AHE3_A/H suitable for under-hood and cabin-mounted automotive electronics where zero-defect reliability is mandatory.
What does the "_A/H" suffix in P6SMB22AHE3_A/H indicate?
The "_A/H" suffix in P6SMB22AHE3_A/H specifies packaging and revision: "A" denotes the revision code per Vishay's internal documentation, and "H" indicates 7" diameter plastic tape-and-reel delivery (750 units per reel). This matches the ordering example on page 3 of datasheet 88370 and confirms the part ships in standard SMT-compatible format ready for pick-and-place assembly.
How does the thermal resistance of P6SMB22AHE3_A/H affect PCB layout?
P6SMB22AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under worst-case 5.0 W steady-state dissipation, designers must ensure adequate copper area and minimize trace length to ground planes. The SMB footprint allows direct use of IPC-7351B standard land patterns without thermal derating penalties.
Can P6SMB22AHE3_A/H be used in bidirectional configurations?
No, P6SMB22AHE3_A/H is unidirectional only, as indicated by the "A" suffix (e.g., P6SMB22A) and absence of "CA" in the part number. Bidirectional variants use the "CA" suffix (e.g., P6SMB22CA) and exhibit symmetrical clamping in both polarities. Using P6SMB22AHE3_A/H in reverse-biased signal paths would result in forward conduction and failure; always verify polarity marking (cathode band) during placement.
