Product details
Overview
P6SMB47CH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 42.3–51.7 V, clamping voltage of 67.8 V at 9.2 A peak pulse current, and DO-214AA (SMB) package. It provides robust ESD and electrical fast transient protection for automotive lighting control modules, power supply input stages, and industrial sensor interfaces.
For engineers reviewing the P6SMB47CH datasheet, P6SMB47CH pinout, P6SMB47CH application, or P6SMB47CH equivalent, key selection criteria include standoff voltage (38.1 V), low leakage (<1 µA @ VWM), AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and thermal resistance (RθJA = 55 °C/W).
Technical Context
The P6SMB47CH uses a glass-passivated silicon junction to achieve fast response time (<1.0 ps from 0 V to VBR(min)) and stable clamping performance under repetitive surge stress. Its unidirectional configuration enables asymmetric protection in DC-biased circuits while maintaining low forward voltage (VF = 3.5 V @ 50 A).
Designed for automotive-grade reliability, it operates across –55 °C to +150 °C junction temperature, meets JESD201 Class 2 whisker resistance, and features matte tin-plated leads compliant with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 42.3 V / 51.7 V - Ensures reliable triggering above system operating voltage with margin against tolerance drift |
| VWM | 38.1 V - Maximum continuous reverse working voltage without significant leakage |
| VC @ IPPM | 67.8 V @ 9.2 A - Clamped voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPPSM | 600 W - Peak pulse power handling per single 10/1000 µs waveform |
| IR @ VWM | <1 µA - Minimal standby power loss and signal integrity impact in high-impedance nodes |
| TJ(max) | +150 °C - Enables operation in under-hood automotive environments and enclosed industrial enclosures |
| RθJA | 55 °C/W - Predictable thermal rise on standard FR-4 PCB with recommended pad layout |

Applications
| Automotive Lighting Control | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting LED driver ICs and microcontrollers from load-dump and inductive kickback in headlight and taillight modules. IC Role / Device Role: Primary overvoltage clamp on 12/24 V supply rail upstream of DC-DC converters and gate drivers. Use Value: Limits transient voltage to ≤67.8 V, preventing latch-up or permanent damage to 40 V-rated logic and power devices. | Use Scenario: Safeguarding analog front-end amplifiers and ADC inputs in 4–20 mA loop-powered sensors exposed to field wiring surges. IC Role / Device Role: Input-stage TVS placed before precision shunt regulators and op-amps. Use Value: Sub-1 µA leakage preserves measurement accuracy; 600 W rating absorbs multiple 1 kV/50 Ω transients per IEC 61000-4-5. |
| Power Supply Input Protection | Motor Drive Gate Driver Protection |
Use Scenario: Secondary surge suppression on AC/DC or DC/DC converter inputs subjected to lightning-induced surges and switching noise. IC Role / Device Role: Final-line defense after bulk MOV or GDT, providing precise clamping before rectifier and controller ICs. Use Value: Tight VBR tolerance (±11%) and low VC/VBR ratio (1.60) minimize stress on downstream 60 V MOSFETs and controllers. | Use Scenario: Protecting high-side and low-side gate drivers in BLDC motor inverters from Miller-induced voltage spikes and shoot-through transients. IC Role / Device Role: Localized clamp on gate drive supply rails (e.g., 15 V bias) near driver IC outputs. Use Value: Fast <1 ps response prevents gate oxide breakdown; DO-214AA footprint allows placement within 5 mm of driver output pins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ47CA | Bidirectional variant; symmetric VBR (42.3–51.7 V) in both polarities; same PPPSM, VC, and package | Required where AC-coupled or floating lines need protection without polarity dependency (e.g., RS-485 bus) | Select P6SMB47CH for DC-biased rails with ground-referenced clamping; choose SMBJ47CA only if bidirectional behavior is explicitly needed |
| 1.5SMC47A | Same VBR range but larger DO-214AB (SMC) package; higher RθJA (40 °C/W), lower IPPM (9.0 A), identical VC (67.8 V) | Used where board space permits larger footprint and higher thermal mass is beneficial (e.g., high-ambient industrial power supplies) | P6SMB47CH offers superior density and AEC-Q101 qualification; 1.5SMC47A may be considered only if existing SMC land pattern must be reused |
Compared with SMBJ47CA and 1.5SMC47A, the P6SMB47CH delivers AEC-Q101 assurance in the smallest qualified SMB outline, enabling compact, automotive-compliant designs without sacrificing clamping precision or surge capacity.

FAQ
What is the polarity configuration of the P6SMB47CH?
The P6SMB47CH is a unidirectional TVS diode with cathode band marking. It conducts only during reverse-bias overvoltage events and blocks forward current up to its rated VF (3.5 V @ 50 A). This configuration is optimized for DC supply rail protection where polarity is fixed, unlike bidirectional variants such as P6SMB47CA.
Does the P6SMB47CH meet automotive qualification standards?
Yes, the P6SMB47CH is AEC-Q101 qualified and tested per ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms. It also satisfies JESD201 Class 2 whisker resistance, J-STD-020 moisture sensitivity level 1, and RoHS/halogen-free compliance - all documented in Taiwan Semiconductor's official A2102 specification release.
What is the maximum clamping voltage of the P6SMB47CH under surge conditions?
The P6SMB47CH has a maximum clamping voltage (VC) of 67.8 V at 9.2 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is guaranteed across temperature and lifetime, ensuring downstream components see no more than 67.8 V during worst-case transients.
Can the P6SMB47CH be used in bidirectional signal lines like CAN or RS-485?
No - the P6SMB47CH is unidirectional and unsuitable for AC or floating bidirectional lines. For such applications, use the bidirectional P6SMB47CA variant, which provides symmetrical clamping in both directions and is explicitly rated for ISO 11898-2 (CAN) and TIA-485-A (RS-485) transient immunity.
What is the thermal resistance and how does it affect PCB layout for the P6SMB47CH?
The P6SMB47CH has RθJA = 55 °C/W and RθJC = 10 °C/W. To maintain TJ ≤ 150 °C under 600 W pulses, ensure ≥25 mm² copper pour on both anode and cathode pads per Taiwan Semiconductor's suggested pad layout. Avoid narrow traces or thermal isolation that would impede heat dissipation.
