Product details
Overview
P6SMB47AHE3_A/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 47 V breakdown voltage (VBR = 44.7–49.4 V at IT = 1.0 mA), 40.2 V stand-off voltage (VWM), 64.8 V maximum clamping voltage (VC) at 9.3 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB47AHE3_A/I datasheet, P6SMB47AHE3_A/I pinout, P6SMB47AHE3_A/I application, or P6SMB47AHE3_A/I equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compliance with J-STD-020 MSL level 1 reflow profile.
Technical Context
The P6SMB47AHE3_A/I operates as a silicon avalanche diode that enters breakdown when reverse voltage exceeds VWM = 40.2 V, limiting transient energy via low-clamp response (VC = 64.8 V @ 9.3 A). Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns).
Designed for automated SMT assembly, it meets JESD201 Class 2 whisker resistance, RoHS compliance, and UL 94 V-0 flammability rating. The matte tin-plated leads are solderable per J-STD-002 and JESD22-B102, with cathode indicated by a band on the SMB case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 44.7–49.4 V at 1.0 mA test current - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| Stand-off Voltage VWM | 40.2 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| Clamping Voltage VC | 64.8 V at 9.3 A IPPM - limits downstream voltage during 10/1000 μs surge, protecting 50 V-rated components |
| Peak Pulse Power PPPM | 600 W - sustains single 10/1000 μs transients without degradation under derated conditions |
| Thermal Resistance RθJA | 100 °C/W - determines junction temperature rise above ambient under 5.0 W steady-state dissipation |
| Operating Temperature Range | −65 °C to +150 °C - supports deployment in automotive engine bays and industrial control cabinets |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |

Use Scenario: Protecting 48 V DC-DC converter outputs against load dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between output rail and chassis ground to clamp transients before they reach downstream regulators and microcontrollers. Use Value: Limits voltage to ≤64.8 V during 100 A/100 ms load dump events, preserving 75 V-rated MOSFETs and PMICs. |
Use Scenario: Shielding analog sensor inputs (e.g., pressure, temperature) in PLC modules from ESD and inductive switching noise. IC Role / Device Role / Timing Role: TVS mounted directly at connector entry point to divert sub-100 ns ESD strikes away from precision op-amps and ADC front-ends. Use Value: Clamps 8 kV contact ESD (IEC 61000-4-2) to <65 V within <1 ns, preventing latch-up or parametric shift in 24-bit sigma-delta converters. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Input Stage |
|
Use Scenario: Safeguarding PoE-powered Ethernet PHYs and magnetics from lightning-induced surges on RJ45 ports. IC Role / Device Role / Timing Role: Paired unidirectional TVS devices on each differential pair, referenced to isolated ground plane. Use Value: Withstands 10/700 μs telecom surges up to 1 kV while maintaining <1 pF junction capacitance to avoid signal integrity degradation. |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters powering USB-C PD devices. IC Role / Device Role / Timing Role: TVS placed across 5–20 V output rails to absorb capacitor discharge transients during hot-plug events. Use Value: Absorbs 600 W peak energy without failure, ensuring no secondary-side voltage overshoot exceeds USB PD specification limits (≤21 V). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ47A-E3/52 (Vishay) | Same VBR range but SMA package (DO-214AC); RθJA = 125 °C/W; lower PPPM = 400 W | Limited to lower-power circuits due to reduced surge handling; not AEC-Q101 qualified | Select when board space allows larger SMA footprint and automotive qualification is unnecessary |
| 1.5SMC47A (ON Semiconductor) | Identical VBR, VWM, VC; same SMB package; AEC-Q101 qualified; RθJA = 100 °C/W | Drop-in replacement with identical thermal and electrical specs; different marking and reel packaging | Choose for dual-sourcing flexibility in automotive production; verify reel code (I vs. H) matches assembly line requirements |
Compared with SMAJ47A-E3/52, P6SMB47AHE3_A/I delivers 50 % higher surge power and automotive qualification; versus 1.5SMC47A, it offers identical performance but distinct traceability and logistics coding for Vishay-specific supply chain integration.

FAQ
What is the exact breakdown voltage range for P6SMB47AHE3_A/I?
The P6SMB47AHE3_A/I has a guaranteed breakdown voltage (VBR) range of 44.7 V to 49.4 V at a test current of 1.0 mA, measured per ANSI/IEEE C62.35. This range ensures consistent avalanche initiation across production lots and temperature extremes, critical for predictable clamping behavior in safety-critical automotive applications.
Is P6SMB47AHE3_A/I suitable for bidirectional transient protection?
No, P6SMB47AHE3_A/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional operation, Vishay specifies part numbers ending in "CA" (e.g., P6SMB47CA). Using P6SMB47AHE3_A/I in AC or floating-line applications risks forward conduction and improper clamping.
Does P6SMB47AHE3_A/I meet automotive reliability standards?
Yes, P6SMB47AHE3_A/I is AEC-Q101 qualified, as confirmed by its "HE3" suffix and documentation in Vishay's 88370 datasheet. It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D, making it suitable for under-hood and body-control module deployments.
What is the maximum clamping voltage of P6SMB47AHE3_A/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB47AHE3_A/I is 64.8 V at a peak pulse current (IPPM) of 9.3 A, tested with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events, enabling safe interface with 75 V-rated components.
How does the SMB package of P6SMB47AHE3_A/I affect thermal performance?
The SMB (DO-214AA) package of P6SMB47AHE3_A/I provides a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W on standard 0.2" × 0.2" copper pads. This enables reliable operation at 5.0 W steady-state dissipation up to +50 °C ambient, supporting compact layout without external heatsinking in most industrial applications.
