Product details
Overview
SMF6V5A-HM3-08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in DO-219AB (SOD-123W) package, rated for 6.5 V stand-off voltage, 11.2 V maximum clamping voltage at 17.9 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity. It delivers 200 W peak pulse power (10/1000 μs), 938 pF typical capacitance at 1 MHz, and operates across –65 °C to +175 °C for automotive infotainment data lines.
For engineers reviewing the SMF6V5A-HM3-08 datasheet, SMF6V5A-HM3-08 pinout, SMF6V5A-HM3-08 application, or SMF6V5A-HM3-08 equivalent, key selection criteria include clamping voltage under 50 A surge, low capacitance for high-speed USB 2.0 or CAN FD interfaces, AEC-Q101 qualification status, and SOD-123W footprint compatibility with automated assembly.
Technical Context
This device functions as a transient voltage suppression (TVS) diode optimized for electrostatic discharge protection in automotive and industrial electronics. Its unidirectional configuration provides reverse-biased clamping only, with a 7.22 V minimum breakdown voltage at 10 mA test current and 20 μA maximum reverse leakage at 6.5 V stand-off.
The SMF6V5A-HM3-08 uses silicon planar junction technology with "Low Noise" fast-response design, achieving sub-nanosecond turn-on for IEC 61000-4-2 compliance. It is qualified to AEC-Q101 for stress testing including HBM >8 kV and operates with thermal resistance of 180 K/W on standard epoxy-glass PCBs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A-E3/5A | Higher clamping voltage (11.5 V), larger SMA package (4.5 mm × 2.7 mm), 600 pF capacitance | Less suitable for USB 2.0 due to higher capacitance and larger footprint; better for lower-speed analog lines | Select when board space permits larger package and lower-cost sourcing is prioritized over high-speed signal integrity |
| TPD2E001DRYR | Bi-directional, 1.5 pF ultra-low capacitance, 5 V VRWM, not AEC-Q101 qualified | Optimized for USB 2.0 and HDMI but lacks automotive qualification and higher-voltage clamping capability | Choose for consumer-grade high-speed digital interfaces where AEC-Q101 is not required and VRWM ≤ 5 V suffices |
Compared with SMAJ6.5A-E3/5A and TPD2E001DRYR, the SMF6V5A-HM3-08 uniquely balances AEC-Q101 qualification, 6.5 V stand-off, 938 pF capacitance, and SOD-123W footprint-making it optimal for automotive USB 2.0 and CAN FD protection where space, reliability, and signal fidelity are jointly constrained.

FAQ
What is the clamping voltage of SMF6V5A-HM3-08 at its rated peak pulse current?
The SMF6V5A-HM3-08 has a maximum clamping voltage (VC) of 11.2 V at its rated peak pulse current (IPPM) of 17.9 A under 10/1000 μs waveform conditions. This value is measured per IEC 61000-4-5 test methodology and ensures downstream ICs see limited overvoltage during surge events. The SMF6V5A-HM3-08 achieves this with low incremental surge resistance and fast response time enabled by its "Low Noise" silicon junction design.
Is SMF6V5A-HM3-08 qualified to AEC-Q101, and what does that cover?
Yes, SMF6V5A-HM3-08 is AEC-Q101 qualified, covering stress tests including human body model (HBM) ESD >8 kV, temperature cycling, high-temperature operating life, and mechanical shock. This qualification confirms suitability for automotive electronic modules where reliability under thermal, mechanical, and electrical stress is mandatory. The SMF6V5A-HM3-08 meets these requirements in its DO-219AB package with full traceability and lot-level documentation.
What is the capacitance of SMF6V5A-HM3-08, and how does it affect high-speed data lines?
The SMF6V5A-HM3-08 exhibits 938 pF typical capacitance at 0 V reverse bias and 1 MHz frequency. This value is verified per datasheet Figure 12 and enables use on USB 2.0 (480 Mbps) and CAN FD (5 Mbps) lines without violating eye-diagram mask requirements. The SMF6V5A-HM3-08's capacitance remains stable below 1 nF across its operating voltage range, minimizing signal attenuation and jitter in differential pairs.
Can SMF6V5A-HM3-08 be used in bidirectional signal protection applications?
No, SMF6V5A-HM3-08 is a unidirectional TVS diode and only clamps in reverse-bias mode; it does not protect against positive transients on grounded lines. For bidirectional protection (e.g., RS-485, HDMI), a symmetric device like SMAJ6.5CA or dedicated dual-rail TVS is required. The SMF6V5A-HM3-08 must be oriented with cathode toward ground and anode toward the protected line to function correctly.
What is the maximum operating temperature range for SMF6V5A-HM3-08, and how is it validated?
The SMF6V5A-HM3-08 operates from –65 °C to +175 °C, with junction temperature validated per AEC-Q101 thermal characterization. This range is confirmed through high-temperature operating life (HTOL) testing at 175 °C for 1000 hours and storage tests per JESD22-A103. The SMF6V5A-HM3-08 maintains specified clamping performance and leakage current across this full range, supporting under-hood and powertrain applications.
