Diodes Incorporated BZX84C6V2T-7-F

Overview

BZX84C6V2T-7-F from Diodes Incorporated is a 6.2 V, 150 mW surface-mount Zener diode in SOT-523 package, rated for ±0.4 V zener voltage tolerance at 5 mA test current, with 10 Ω maximum zener impedance and 3.0 µA maximum reverse leakage at 4.0 V, used for precision voltage regulation and reference in low-power analog circuits.

For engineers reviewing the BZX84C6V2T-7-F datasheet, BZX84C6V2T-7-F pinout, BZX84C6V2T-7-F application, or BZX84C6V2T-7-F equivalent, key selection criteria include zener voltage stability over temperature (±0.4 to +3.7 mV/°C), ultra-small footprint compatibility with high-density PCB layouts, and RoHS-compliant lead-free plating for automated assembly.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load or supply conditions. It features planar die construction for consistent parametric performance and low thermal resistance (833 °C/W) when mounted on FR-4 with recommended pad layout.

Its 150 mW power rating and 5 mA nominal test current define its regulation range, while the 10 Ω dynamic impedance at I_ZT ensures minimal voltage deviation under small-signal current variations. The device exhibits a positive temperature coefficient (+0.4 to +3.7 mV/°C) above 5 V, enabling predictable drift behavior in temperature-sensitive references.

FAQ

What is the maximum reverse voltage before breakdown for BZX84C6V2T-7-F?

The BZX84C6V2T-7-F begins controlled reverse breakdown at a nominal 6.2 V, with guaranteed regulation between 5.8 V (min) and 6.6 V (max) at 5 mA test current. Below 4.0 V reverse bias, leakage remains ≤3.0 µA; operation below 5.8 V does not achieve stable Zener conduction.

Can BZX84C6V2T-7-F be used in place of a 5.1 V Zener diode?

No - it is not a drop-in replacement for 5.1 V Zeners like BZX84C5V1T. Its 6.2 V nominal breakdown and 5.8–6.6 V tolerance range exceed the 4.8–5.4 V window of the 5.1 V part. Substituting would shift reference or clamp thresholds by >1 V, risking circuit malfunction.

Does BZX84C6V2T-7-F require a series current-limiting resistor?

Yes - a series resistor is mandatory to limit forward or reverse current to stay within the 150 mW power rating. For example, at 12 V supply and 6.2 V regulation, a minimum 390 Ω resistor limits current to ~15 mA, keeping dissipation at ~93 mW. Without it, instantaneous failure occurs.

Is the SOT-523 package compatible with standard pick-and-place equipment?

Yes - the SOT-523 package (1.6 mm × 0.8 mm, 0.5 mm pitch) is supported by Class II and III placement machines with 0201-capable nozzles and vision alignment. Diodes Incorporated provides recommended pad layout (AP02001.pdf) and tape-and-reel packaging (3000/reel, -7-F suffix) for automated assembly.
