Product details
Overview
P6SMB62CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 53.0 V standoff voltage (VWM), 65.1 V maximum breakdown voltage (VBR), 85.0 V clamping voltage (VC) at 7.1 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the P6SMB62CAHE3/5B datasheet, P6SMB62CAHE3/5B pinout, P6SMB62CAHE3/5B application, or P6SMB62CAHE3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMB (DO-214AA) package dimensions, thermal resistance data, and real-world design implications for transient immunity planning.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping behavior during positive and negative transients. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables rapid energy diversion without voltage overshoot beyond VC = 85.0 V.
The device is rated for TJ = –65 °C to +150 °C operation and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its RθJA = 100 °C/W and RθJL = 20 °C/W define thermal limits under pulsed conditions, requiring PCB copper pad area (0.2" × 0.2") for full 600 W rating compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe working margin below breakdown. |
| VBR (min/max) | 58.9 V / 65.1 V - Measured at 1.0 mA IT; ensures predictable turn-on threshold across production lot and temperature range. |
| VC @ IPPM | 85.0 V at 7.1 A - Clamped voltage during 10/1000 μs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and sealed industrial enclosures. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64CA | Same SMB package, 64 V VWM, 71.1 V VBR, 103 V VC @ 5.8 A; lower PPPM (400 W); no AEC-Q101 option. | Limited to commercial-grade industrial use; insufficient for automotive under-hood surge requirements. | Select when cost sensitivity outweighs automotive qualification and 600 W headroom. |
| SMCJ64CA | Higher-power SMC package (DO-214AB), same 64 V VWM, 71.1 V VBR, but 103 V VC @ 32.4 A; 1500 W PPPM; AEC-Q101 available. | Requires larger PCB area (0.325" × 0.260"); suited for main power rail protection rather than signal-line placement. | Choose for higher-energy surge zones where board space permits and clamping voltage margin allows. |
Compared with SMAJ64CA, P6SMB62CAHE3/5B delivers 50 % higher peak pulse power and automotive qualification; versus SMCJ64CA, it trades 2.5× PCB area for tighter layout integration in space-constrained sensor modules.

FAQ
What does the "CA" suffix indicate in P6SMB62CAHE3/5B?
The "CA" suffix denotes a bidirectional configuration: P6SMB62CAHE3/5B provides symmetrical clamping for both positive and negative voltage transients, unlike unidirectional "A" variants. This eliminates polarity concerns during PCB layout and enables protection of AC-coupled or floating signal paths without external diode pairing. The device functions identically in either direction, with matched VBR, VC, and IPPM values.
Is P6SMB62CAHE3/5B qualified for automotive applications?
Yes, P6SMB62CAHE3/5B is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure ("HE3" suffix) and documentation. It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D. This qualification supports deployment in engine control units, body electronics, and ADAS sensor modules where reliability under thermal and electrical stress is mandatory.
What is the clamping voltage of P6SMB62CAHE3/5B and why does it matter?
The clamping voltage (VC) of P6SMB62CAHE3/5B is 85.0 V at 7.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value defines the maximum voltage seen by downstream circuitry during a surge event. A lower VC relative to VBR (clamping ratio ≈ 1.30) minimizes overvoltage stress on protected ICs - essential for safeguarding 24 V system interfaces connected to 3.3 V or 5 V logic devices.
How does the SMB (DO-214AA) package of P6SMB62CAHE3/5B affect thermal performance?
The SMB package of P6SMB62CAHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W. To achieve full 600 W pulse rating, the device must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Smaller pads or insufficient copper reduce power handling and risk thermal runaway during repetitive surges.
Can P6SMB62CAHE3/5B replace P6SMB62AHE3/5B in a design?
No - P6SMB62CAHE3/5B is bidirectional, while P6SMB62AHE3/5B is unidirectional. Substituting them requires verifying circuit polarity: unidirectional types require correct cathode orientation and cannot protect against reverse-polarity transients. Bidirectional operation is mandatory for AC signals, floating grounds, or dual-rail systems. Layout changes and functional validation are required before interchange.
