Product details
Overview
P6SMB62CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 53.0 V standoff voltage (VWM), 62.0 V minimum breakdown voltage (VBR), 85.0 V maximum clamping voltage (VC) at 7.1 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6SMB62CAHE3_A/I datasheet, P6SMB62CAHE3_A/I pinout, P6SMB62CAHE3_A/I application, or P6SMB62CAHE3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, low thermal resistance (RθJL = 20 °C/W), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped surge protector using an avalanche junction structure, delivering symmetrical reverse/forward conduction for bidirectional transient suppression. Its glass-passivated chip junction ensures stable VBR tolerance (±5% min–max range: 58.9–65.1 V) and fast response time (<1 ns), with clamping performance validated under repetitive 0.01% duty-cycle 10/1000 μs pulses.
Thermally, it sustains operation from −65 °C to +150 °C junction temperature, with RθJA = 100 °C/W (on standard pad layout) and RθJL = 20 °C/W - enabling reliable energy dissipation during transient events without thermal runaway. The matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin below clamping threshold. |
| VBR (min) | 58.9 V at 1.0 mA test current - Minimum voltage at which avalanche conduction initiates; ensures predictable turn-on across temperature. |
| VC @ IPPM | 85.0 V at 7.1 A - Clamped voltage during 10/1000 μs surge; determines maximum stress imposed on protected downstream circuitry. |
| PPPM | 600 W - Peak pulse power handling capacity; enables robust protection against IEC 61000-4-5 Level 4 surges when properly mounted. |
| IPPM | 7.1 A - Peak pulse current corresponding to VC; used to size PCB trace width and verify thermal derating above 25 °C. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and high-ambient industrial settings. |
| MSL Level | Level 1 per J-STD-020 - No floor life limitation or bake requirement prior to reflow; simplifies SMT manufacturing flow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64CA | Same SMB package, 64 V VBR min, 100 V VC @ 6.4 A, 400 W PPPM, non-AEC-Q101 | Limited to commercial-grade industrial use; lacks automotive qualification and lower clamping ratio (VC/VBR = 1.56 vs. 1.36 for P6SMB62CAHE3_A/I) | Select when cost sensitivity outweighs automotive compliance and tighter clamping is not required. |
| 1.5KE68CA | DO-201 package, 68 V VBR min, 112 V VC @ 5.4 A, 1500 W PPPM, through-hole mounting | Higher power but incompatible with SMT assembly; larger footprint and higher inductance limits high-speed signal line use. | Choose only for legacy through-hole designs needing higher single-pulse energy absorption, not for new SMT layouts. |
Compared with SMAJ64CA and 1.5KE68CA, P6SMB62CAHE3_A/I delivers superior clamping efficiency (lower VC/VBR ratio), AEC-Q101 qualification for automotive deployment, and optimized thermal performance in compact SMB packaging - making it the preferred choice for space-constrained, high-reliability SMT applications.

FAQ
What is the clamping voltage of P6SMB62CAHE3_A/I at its rated peak pulse current?
The P6SMB62CAHE3_A/I has a maximum clamping voltage (VC) of 85.0 V at its specified peak pulse current (IPPM) of 7.1 A, measured under the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2. The P6SMB62CAHE3_A/I maintains this clamping performance across its full operating temperature range.
Is P6SMB62CAHE3_A/I qualified for automotive applications?
Yes, P6SMB62CAHE3_A/I is AEC-Q101 qualified - explicitly stated in the Vishay ordering information table (page 3) where "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified variants. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD, validating suitability for under-hood and chassis-mounted automotive electronics. The P6SMB62CAHE3_A/I meets these requirements without derating.
What does the "CA" suffix indicate in P6SMB62CAHE3_A/I?
The "CA" suffix in P6SMB62CAHE3_A/I designates a bidirectional configuration - meaning the device provides symmetrical transient suppression in both forward and reverse directions, with identical VWM, VBR, and VC characteristics across polarity. Unlike unidirectional "A" variants, P6SMB62CAHE3_A/I has no cathode marking and is used where AC-coupled or differential signal lines require equal protection regardless of voltage polarity.
What is the standoff voltage (VWM) of P6SMB62CAHE3_A/I and why does it matter?
The standoff voltage (VWM) of P6SMB62CAHE3_A/I is 53.0 V - the maximum DC or RMS voltage that can be continuously applied without triggering significant leakage current (>1.0 μA). This parameter ensures the P6SMB62CAHE3_A/I remains non-conductive during normal operation while providing sufficient margin below its 58.9 V minimum breakdown voltage, preventing false triggering on nominal 48 V or 24 V industrial and automotive power rails.
How is thermal performance characterized for P6SMB62CAHE3_A/I?
P6SMB62CAHE3_A/I is characterized with RθJL = 20 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads), enabling precise thermal modeling during surge events. These values confirm efficient heat transfer to the PCB leads and define safe operating area boundaries - critical for repetitive surge applications where cumulative heating could otherwise degrade long-term reliability of the P6SMB62CAHE3_A/I.
