It provides robust ESD and electrical fast transient protection for automotive lighting control modules, industrial power supply inputs, and CAN bus interface circuits.
For engineers reviewing the P6SMB150CH datasheet, P6SMB150CH pinout, P6SMB150CH application, or P6SMB150CH equivalent, this device delivers AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, <1 μA reverse leakage at 121 V, and sub-1 ps response time - critical for high-reliability 12 V/24 V automotive and industrial systems.
Technical Context
The P6SMB150CH is a unidirectional/bidirectional TVS diode configured as a single die in a glass-passivated junction structure. Its bidirectional operation (indicated by "CH" suffix) enables symmetrical clamping in both polarities, supporting protection of AC-coupled or floating signal lines without polarity dependency.
It operates across –55 °C to +150 °C junction temperature, with thermal resistance RθJC = 10 °C/W and RθJA = 55 °C/W. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, enabling compatibility with standard reflow profiles and automated SMT assembly.
Key Specifications

IC Role / Device Role: First-line transient suppression on 24 V supply lines entering isolated signal conditioning circuitry. Use Value: Clamps 1 kV/500 A 10/1000 µs surges to <215 V within <1 ps, preserving integrity of ±10 V ADC front-ends and optocoupler isolation barriers. |
| CAN Bus Interface Protection | AC-DC Adapter Surge Suppression |
Use Scenario: Shielding CAN transceivers in body control modules from coupled transients on shared vehicle power domains. IC Role / Device Role: Bidirectional shunt clamp between CAN_H/CAN_L differential pair and chassis ground. Use Value: Symmetric clamping prevents common-mode overvoltage exceeding transceiver absolute maximum ratings (±40 V), maintaining bus communication during battery disconnect events. | Use Scenario: Protecting secondary-side rectifier and controller ICs in universal-input AC-DC adapters subjected to line surges. IC Role / Device Role: Parallel-connected TVS across bulk capacitor output (e.g., 385 V DC link) to absorb residual surge energy after MOV stage. Use Value: Absorbs 600 W peak pulses without thermal runaway, extending capacitor life and preventing controller brownout or reset during EN 61000-4-5 Level 4 testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Same DO-214AA package, identical VBR (135–165 V), but rated at 600 W with slightly higher VC = 243 V @ 2.5 A. | Higher clamping voltage reduces margin for 150 V-rated downstream components; suitable where board-level layout allows tighter voltage tolerance. | Select SMBJ150CA only if existing design already uses SMBJ-series footprints and clamping margin permits 243 V peak. |
| 1.5KE150CA | Through-hole DO-201 package, same VBR/VC specs, but larger footprint and lower thermal efficiency (RθJA ≈ 100 °C/W). | Not suitable for high-density SMT designs; preferred in legacy through-hole power supplies or prototyping where reflow constraints exist. | Choose 1.5KE150CA only when DO-201 mounting is mandated or thermal derating can be accommodated via heatsinking. |
Compared with SMBJ150CA and 1.5KE150CA, the P6SMB150CH offers optimal balance of low-profile SMT compatibility, AEC-Q101 qualification, and tight 215 V clamping - making it the preferred choice for new automotive and industrial designs requiring validated reliability and space-efficient layout.

FAQ
What does the "CH" suffix indicate in P6SMB150CH?
The "CH" suffix denotes a bidirectional configuration - meaning the P6SMB150CH functions identically in both polarities, with symmetrical breakdown and clamping characteristics. This eliminates polarity concerns during PCB layout and makes it ideal for protecting AC-coupled signals or floating buses like CAN, unlike unidirectional "H" variants that require correct anode/cathode orientation. The P6SMB150CH is marked "NHJ" per TSC's ordering code table.
Is P6SMB150CH AEC-Q101 qualified?
Yes, the P6SMB150CH is explicitly AEC-Q101 qualified per the manufacturer's datasheet (Version A2102). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - confirming suitability for automotive under-hood and cabin applications where reliability under thermal and mechanical stress is mandatory. Aetrix Electronics provides full traceability documentation upon request for P6SMB150CH.
What is the maximum clamping voltage of P6SMB150CH and at what current?
The maximum clamping voltage (VC) of the P6SMB150CH is 215 V, measured at a peak pulse current (IPPM) of 2.9 A using the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream components remain within their absolute maximum voltage ratings. The P6SMB150CH achieves this with <1 ps response time.
Can P6SMB150CH replace P6SMB150AH in an existing design?
No - P6SMB150CH and P6SMB150AH are not interchangeable. P6SMB150AH is unidirectional (anode/cathode polarity matters), while P6SMB150CH is bidirectional. Swapping them requires verifying layout polarity, clamping symmetry requirements, and whether the application relies on forward conduction behavior. The P6SMB150CH has VBR = 135–165 V and VC = 215 V @ 2.9 A; P6SMB150AH shares identical electrical specs but lacks symmetrical conduction. Always validate with actual surge testing before substitution.
What is the moisture sensitivity level (MSL) and reflow profile compatibility of P6SMB150CH?
The P6SMB150CH has Moisture Sensitivity Level 1 per J-STD-020 - meaning it may be stored indefinitely at ≤30 °C/60% RH without baking prior to assembly. It is fully compatible with standard Pb-free reflow profiles (peak temperature ≤260 °C, 20–40 sec above 217 °C), supported by matte tin-plated leads meeting J-STD-002 solderability requirements. The DO-214AA package's low mass and thermal design ensure uniform heating during reflow, minimizing risk of tombstoning or voiding when used with recommended pad layouts.
