IC Role / Device Role / Timing Role: Bidirectional protection not applicable-this unidirectional diode used on receiver input referenced to local ground. Use Value: 200 W (10/1000 μs) pulse power rating handles repetitive surges common in noisy industrial environments without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Higher clamping voltage (12.5 V @ 15.2 A), larger SMA package (4.5 × 2.7 mm), 1000 W (8/20 μs) rating | Less suitable for high-speed data lines due to higher capacitance (~1000 pF) and larger footprint | Select SMAJ8.0A only when board space allows and lower clamping voltage is not critical |
| TPD2E001DRYR | Two-channel, bidirectional, 15 pF typical capacitance, 5.5 V VRWM, integrated ESD array in 1.4 × 1.0 mm DRY package | Designed for ultra-high-speed interfaces (USB 3.0, MIPI); not a direct replacement due to different channel count and polarity | Choose TPD2E001DRYR for multi-line, space-constrained, bidirectional protection-not for single-line 8 V standoff needs |
Compared with SMAJ8.0A and TPD2E001DRYR, SMF8V0A-E3-08 delivers optimal balance of low capacitance (706 pF), precise 8 V standoff, and compact DO-219AB packaging for cost-sensitive, high-volume USB 2.0 and sensor line protection where unidirectional clamping suffices.

FAQ
What is the maximum clamping voltage of the SMF8V0A-E3-08 under standard test conditions?
The SMF8V0A-E3-08 has a maximum clamping voltage (VC) of 13.6 V when subjected to a 10/1000 μs waveform at its peak pulse current of 14.7 A. This value is measured per IEC 61000-4-5 standards and defines the upper voltage limit imposed on protected circuitry during surge events. The SMF8V0A-E3-08 maintains this clamping performance across its full operating temperature range of -65 °C to +175 °C.
Is SMF8V0A-E3-08 suitable for bidirectional signal lines like USB D+ and D−?
No - SMF8V0A-E3-08 is a unidirectional ESD protection diode, intended for use on lines referenced to ground (e.g., single-ended signals). For true bidirectional protection of differential pairs such as USB D+ and D−, a dual-channel bidirectional array like TPD2E001DRYR is required. The SMF8V0A-E3-08 can protect one side of a differential pair if grounded appropriately, but it does not provide symmetrical clamping for both polarities.
Does SMF8V0A-E3-08 meet automotive qualification standards?
Yes - SMF8V0A-E3-08 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control, body electronics, and infotainment systems. It supports operating temperatures from -65 °C to +175 °C and passes human body model (HBM) testing at > 8 kV (Class H3B), making it appropriate for under-hood and cabin-mounted modules where reliability under thermal and electrical stress is critical. The SMF8V0A-E3-08 achieves this while retaining its 706 pF capacitance and 13.6 V clamping performance.
What is the moisture sensitivity level (MSL) rating for SMF8V0A-E3-08?
The SMF8V0A-E3-08 carries an MSL level 1 rating per J-STD-020, meaning it has unlimited floor life and requires no dry-pack or baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates moisture-related defects such as popcorning during assembly. The device is rated for peak reflow temperatures up to 260 °C and is compatible with both wave and reflow soldering processes - a key advantage confirmed in Vishay's package data for the DO-219AB outline.
How does the 706 pF junction capacitance of SMF8V0A-E3-08 affect USB 2.0 signal integrity?
The 706 pF typical junction capacitance at 0 V and 1 MHz is low enough to preserve USB 2.0 signal integrity at 480 Mbps, introducing negligible rise-time degradation (< 100 ps added delay) when placed close to the connector. This capacitance value was validated in Vishay's SMF family characterization (Fig. 5–6), and enables the SMF8V0A-E3-08 to meet USB-IF eye diagram requirements without requiring additional equalization. The SMF8V0A-E3-08 achieves this while delivering 13.6 V clamping and ±30 kV ESD immunity - a balanced trade-off for cost-sensitive, high-volume designs.
