Diodes Incorporated BZX84C11TS-7-F

Overview

BZX84C11TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 11 V (nominal) Zener elements in a single SOT-363 package, rated for 200 mW total power dissipation, 5 mA test current, and ±0.6 V zener voltage tolerance at 25°C - used for precision voltage clamping and reference in compact power management circuits.

For engineers reviewing the BZX84C11TS-7-F datasheet, BZX84C11TS-7-F pinout, BZX84C11TS-7-F application, or BZX84C11TS-7-F equivalent, key selection criteria include zener voltage accuracy (10.4–11.6 V), low reverse leakage (≤0.1 µA at 8 V), temperature coefficient (5.4 to 9.0 mV/°C), and ultra-small SOT-363 footprint for space-constrained PCB layouts.

Technical Context

This triple Zener array integrates three electrically isolated diodes sharing only mechanical packaging - no internal connection between anodes or cathodes. Each element operates independently with identical electrical specs: 11 V nominal zener voltage, 5 mA zener test current, and 200 mW total package power rating derated linearly above 25°C ambient.

The device uses alloy-42 leadframe with matte tin plating, complies with RoHS and Diodes Inc.'s "Green" policy (halogen-free molding compound for date codes UO and newer), and meets UL 94V-0 flammability rating with moisture sensitivity level 1 per J-STD-020D.

FAQ

What is the maximum power dissipation per Zener element in BZX84C11TS-7-F?

The device has a total package power rating of 200 mW - not per element. All three Zeners share this limit; simultaneous full-power operation of all three exceeds rating. Derating is required above 25°C ambient per Figure 1, and thermal design must account for cumulative junction heating.

Does BZX84C11TS-7-F have a common cathode or anode configuration?

No. BZX84C11TS-7-F features three fully isolated Zener diodes - no shared terminals. Each has its own dedicated anode (A1–A3) and cathode (C1–C3), enabling independent circuit connections without electrical coupling.

Is the temperature coefficient of BZX84C11TS-7-F positive or negative?

The temperature coefficient is positive: +5.4 to +9.0 mV/°C at 5 mA test current. This means zener voltage increases with rising junction temperature - critical for designs requiring predictable drift behavior in thermally variable environments.

Can BZX84C11TS-7-F be used in place of a single 11 V Zener diode?

Yes - any one pair (e.g., A1/C1) functions as a standalone 11 V Zener. The remaining two elements remain unused but do not affect performance. This flexibility supports design reuse and simplifies inventory by consolidating single- and multi-Zener requirements.
