Diodes Incorporated BZX84C6V2-7

Overview

BZX84C6V2-7 from Diodes Incorporated is a 350 mW surface-mount Zener diode with nominal zener voltage 6.2 V, ±5% tolerance (5.8–6.6 V), 10 Ω dynamic impedance at 5 mA test current, and 4.0 µA maximum reverse leakage at 4.0 V. It operates in SOT23 package and serves as precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.

For engineers reviewing the BZX84C6V2-7 datasheet, BZX84C6V2-7 pinout, BZX84C6V2-7 application, or BZX84C6V2-7 equivalent, key selection criteria include zener voltage accuracy, thermal resistance (357 °C/W), power derating above +25°C, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This Zener diode uses planar die construction to ensure stable breakdown characteristics and low temperature coefficient (+0.4 mV/°C). Its 350 mW power rating is valid only when terminals are held at ambient temperature; derating begins at +25°C per Figure 1.

The device exhibits 10 Ω zener impedance at I_ZT = 5 mA and 150 Ω at I_ZK = 1.0 mA, enabling stable regulation across moderate load variations. Reverse leakage remains ≤3.0 µA at VR = 4.0 V, supporting low-quiescent-current bias networks.

FAQ

What is the maximum reverse voltage this diode can withstand before breakdown?

The BZX84C6V2-7 has a nominal zener voltage of 6.2 V with a guaranteed range of 5.8 V to 6.6 V at 5 mA test current. Breakdown occurs within this range under reverse bias; operation above 6.6 V risks exceeding power limits unless current is strictly limited by external series resistance.

Is this part suitable for automotive applications?

Yes - BZX84C6V2-7 is qualified to AEC-Q101 standards, confirming its suitability for automotive applications including engine control, body electronics, and ADAS sensor interfaces where reliability under thermal cycling and humidity stress is required.

How does thermal derating affect its power handling capability?

Power dissipation must be linearly derated above +25°C ambient: from 350 mW at 25°C down to 0 mW at approximately +150°C, based on a thermal resistance of 357 °C/W. Derating follows the curve in Figure 1 of DS18001 Rev. 33-2.

What is the significance of the "-7" suffix in the part number?

The "-7" denotes standard-compliance SOT23 packaging in 3,000-piece tape-and-reel format (per ordering information table). It distinguishes this variant from "-13" (10,000-piece reel) and "Q-" prefixed automotive versions, with identical electrical and thermal specifications.
