Diodes Incorporated BZX84C24TS-7-F

Overview

BZX84C24TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 24 V Zener elements in a single SOT-363 package, rated for 200 mW total power dissipation, 70 Ω maximum Zener impedance at 5 mA, and reverse current ≤0.1 µA at 16.8 V, used for precision voltage regulation and overvoltage protection in compact DC power rails.

For engineers reviewing the BZX84C24TS-7-F datasheet, BZX84C24TS-7-F pinout, BZX84C24TS-7-F application, or BZX84C24TS-7-F equivalent, key selection criteria include nominal Zener voltage (24.0 V), tolerance (±5%), thermal resistance (625 °C/W), low leakage (<0.1 µA), and triple-diode integration in ultra-small SOT-363 for space-constrained biasing and clamping circuits.

Technical Context

This device integrates three electrically isolated Zener diodes sharing only mechanical packaging-no internal connection-enabling independent voltage reference or clamping functions per element. Each diode exhibits a nominal Zener voltage of 24.0 V with ±5% tolerance (22.8–25.6 V) and temperature coefficient of +18.4 to +22.0 mV/°C.

It operates across –65 °C to +150 °C, delivers stable regulation at test current I_ZT = 5 mA, and maintains low dynamic impedance (Z_ZT ≤ 70 Ω) and knee impedance (Z_ZK ≤ 250 Ω) under specified conditions, supporting reliable performance in low-power analog monitoring and supply rail stabilization.

FAQ

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

The BZX84C24TS-7-F has a nominal Zener voltage of 24.0 V with a guaranteed range of 22.8 V to 25.6 V at 5 mA test current. Its breakdown is characterized by controlled avalanche conduction-not catastrophic failure-so it reliably regulates at voltages within this band when properly biased. It is not rated for sustained reverse voltage beyond its specified Zener range.

Can all three diodes be used simultaneously without thermal interaction?

Yes-the three Zener elements are fully isolated internally, sharing only the SOT-363 package substrate. Thermal coupling is minimal due to low individual power dissipation (≤200 mW total) and the package's 625 °C/W R_θJA. Simultaneous operation is supported provided total dissipated power remains within derated limits per ambient temperature.

Is this device suitable for ESD protection in high-speed data lines?

No-this is a general-purpose Zener diode array optimized for DC voltage regulation and low-frequency clamping, not ESD suppression. Its capacitance is not characterized for high-speed signals, and its response time is unsuitable for sub-nanosecond transients. Use dedicated TVS arrays like D3V3M1U2UP for USB or Ethernet ESD protection.

How does the temperature coefficient affect regulation accuracy over temperature?

The BZX84C24TS-7-F exhibits a positive temperature coefficient of +18.4 to +22.0 mV/°C. Over a 100 °C range (e.g., –25 °C to +75 °C), Zener voltage may shift up to ~2.2 V-requiring system-level compensation if <1% voltage stability is required. For tighter drift control, consider temperature-compensated references or feedback-based regulators.
