Product details
Overview
P6SMB62AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for robust overvoltage protection of sensitive electronics. It features a 53.0 V stand-off voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1.0 mA test current, and clamps transients to ≤85.0 V at 7.1 A peak pulse current (IPPM) under 10/1000 μs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P6SMB62AHE3_A/I datasheet, P6SMB62AHE3_A/I pinout, P6SMB62AHE3_A/I application, or P6SMB62AHE3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, 600 W peak pulse power rating, low 0.104 %/°C VBR temperature coefficient, and SMB (DO-214AA) package compatibility with automated SMT assembly.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to achieve fast response (<1 ns) and low incremental surge resistance. Its 600 W peak pulse power rating is specified per 10/1000 μs waveform at 0.01 % duty cycle, with thermal derating above 25 °C governed by RθJA = 100 °C/W.
The device is rated for -65 °C to +150 °C operating junction temperature, meets J-STD-020 MSL Level 1 (peak reflow 260 °C), and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Polarity is marked by a cathode band on the SMB package body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown |
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1.0 mA - tight breakdown tolerance ensures predictable turn-on across temperature and production lot |
| VC @ IPPM | ≤85.0 V at IPPM = 7.1 A - clamping voltage limits downstream IC stress during 10/1000 μs transients |
| PPPM | 600 W - peak pulse power handling capability enables protection against high-energy surges like ISO 7637-2 Pulse 1/2a/5a |
| TJ max | +150 °C - supports operation in under-hood automotive environments and high-ambient industrial settings |
| Package | SMB (DO-214AA) - standardized 2-pin surface-mount outline with 0.205" × 0.220" footprint and 0.077" height for high-density PCB layouts |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing per AEC specification |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity indicated by cathode band. Dimensions: 3.94 mm × 2.20 mm × 1.52 mm (L × W × H); recommended pad layout: 5.0 mm × 5.0 mm copper area per terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to circuit ground or lower-potential rail; conducts during forward surge events (e.g., reverse battery connection) |
| Cathode | Clamping node | Connected to protected line (e.g., 48 V supply rail); initiates avalanche breakdown when transient exceeds VWM |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables compliance with ISO 7637-2 and IEC 61000-4-5 surge immunity requirements without external current limiting |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control modules, ADAS sensors, and infotainment power supplies |
| Glass passivated junction | Ensures stable VBR and low leakage (<1.0 μA at VWM) over lifetime and temperature cycling |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow assembly without moisture sensitivity concerns or baking requirements |
| Low VBR tempco (0.104 %/°C) | Maintains consistent clamping threshold across -40 °C to +125 °C ambient, critical for precision power rail protection |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A | Same SMB package, 60 V VWM, 66.7–73.7 V VBR, 87.1 V VC @ 6.9 A; no AEC-Q101 qualification | Commercial-grade only; not suitable for automotive OEM designs requiring AEC validation | Select SMAJ60A only for cost-sensitive industrial or consumer applications where automotive qualification is unnecessary |
| 1.5SMC62A | Higher-power SMC package (7.11 mm × 6.22 mm), same 53.0 V VWM, but 93.6 V VC @ 6.4 A; AEC-Q101 available with HM3 suffix | Larger footprint and higher clamping voltage reduce suitability for space-constrained 48 V rail protection | Choose 1.5SMC62A when system-level surge energy exceeds 600 W or board layout allows larger SMC footprint |
Compared with SMAJ60A and 1.5SMC62A, P6SMB62AHE3_A/I uniquely combines AEC-Q101 qualification, SMB footprint compactness, and lowest clamping voltage (85.0 V) among 53 V-class TVS diodes - making it optimal for automotive and high-reliability industrial 48 V systems where board space and clamping performance are critical.

FAQ
What is the maximum clamping voltage of the P6SMB62AHE3_A/I under standard test conditions?
The P6SMB62AHE3_A/I has a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current (IPPM) of 7.1 A using the 10/1000 μs waveform. This value is measured at TA = 25 °C with devices mounted on 5.0 mm × 5.0 mm copper pads per terminal, and represents the upper limit of voltage seen by protected circuitry during surge events. The P6SMB62AHE3_A/I maintains this clamping performance across its full operating temperature range.
Is the P6SMB62AHE3_A/I qualified for automotive applications?
Yes, the P6SMB62AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's P6SMB datasheet (Document Number: 88370, Revision: 09-Jan-2024). It undergoes stress testing including high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and human-body-model ESD per AEC-Q101 Rev G. This qualification makes the P6SMB62AHE3_A/I suitable for use in automotive powertrain, chassis, and body electronics.
What does the "_A/I" suffix indicate in P6SMB62AHE3_A/I?
The "_A/I" suffix in P6SMB62AHE3_A/I denotes the packaging configuration: "A" indicates the base part is unidirectional, "I" specifies 13-inch diameter plastic tape-and-reel delivery with 3200 units per reel. This format aligns with Vishay's ordering convention where "H" would denote 7-inch reels (750 units), and "I" confirms the larger-volume industrial packaging option compatible with high-speed pick-and-place equipment.
How does the thermal resistance of the P6SMB62AHE3_A/I affect its surge handling capability?
The P6SMB62AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended pad layout. This value directly impacts its ability to sustain repetitive surges: as ambient temperature rises above 25 °C, the device's peak pulse power must be derated per Figure 2 in the datasheet. For example, at TA = 85 °C, the usable PPPM drops to ~420 W - meaning the P6SMB62AHE3_A/I requires careful thermal design in high-ambient environments to maintain full 600 W rating.
Can the P6SMB62AHE3_A/I be used in bidirectional configurations?
No, the P6SMB62AHE3_A/I is a unidirectional TVS diode, as indicated by the "A" (not "CA") in its part number and confirmed by its electrical characteristics table listing only VWM, VBR, and ID for unidirectional operation. Bidirectional variants in the P6SMB series use the "CA" suffix (e.g., P6SMB62CA). Using the P6SMB62AHE3_A/I in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit.
