Diodes Incorporated BZX84C16Q-13-F

Overview

BZX84C16Q-13-F from Diodes Incorporated is a 16V, 350mW surface-mount Zener diode in SOT23 package, rated for 5mA test current with ±6.25% voltage tolerance (15.3V–17.1V), 40Ω dynamic impedance at 5mA, and 0.1µA maximum reverse leakage at 11.2V. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.

For engineers reviewing the BZX84C16Q-13-F datasheet, BZX84C16Q-13-F pinout, BZX84C16Q-13-F application, or BZX84C16Q-13-F equivalent, key selection criteria include Zener voltage accuracy at 5mA, thermal resistance (357°C/W), automotive-grade qualification (AEC-Q101), RoHS/Green compliance, and SOT23 footprint compatibility with automated assembly.

Technical Context

This device operates in reverse-bias breakdown mode to maintain stable voltage across its terminals under varying load or supply conditions. Its planar die construction ensures consistent Zener characteristics and low temperature coefficient (±0.4 mV/°C typical near 16V), enabling reliable regulation in ambient temperatures from –65°C to +150°C.

The SOT23 package supports high-density PCB layouts and reflow soldering per J-STD-020 Level 1 moisture sensitivity. Terminal plating uses matte tin over Alloy 42 leadframe, ensuring MIL-STD-202-compliant solderability without lead or halogen content.

FAQ

What is the maximum reverse voltage (V_R) before significant leakage occurs?

The BZX84C16Q-13-F exhibits ≤0.1µA reverse current at 11.2V (70% of nominal Zener voltage). At 14.0V (87.5% of nominal), leakage remains ≤1.0µA per datasheet Figure 2, confirming stable operation below breakdown threshold.

Is this part suitable for use in high-humidity environments?

Yes. The SOT23 package meets J-STD-020 Moisture Sensitivity Level 1, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. Its UL 94V-0 molded plastic body provides inherent moisture resistance for IPC Class 2/3 assemblies.

How does the "Q" suffix affect specifications compared to non-Q versions?

"Q" denotes automotive qualification per AEC-Q101, including additional stress testing (HTOL, TCT, UHAST), tighter parametric screening, and lot-level traceability. Electrical specs (V_Z, Z_ZT, I_R) remain identical to standard BZX84C16-13-F, but failure rate is statistically validated for automotive lifetimes.

Can this Zener diode replace a 15V or 18V variant in an existing design?

No. The 16V nominal value falls outside the ±5% overlap zone of 15V (14.25–15.75V) and 18V (17.1–18.9V) parts. Substituting would shift reference/clamp voltage beyond acceptable tolerance bands in precision circuits, risking ADC errors or insufficient overvoltage protection.
