Diodes Incorporated BZX84C9V1TS-7-F

Overview

BZX84C9V1TS-7-F from Diodes Incorporated is a triple-element, ultra-small surface-mount Zener diode array in SOT-363 package, rated for 9.1 V nominal zener voltage (±5.5% tolerance), 200 mW power dissipation, and 15 Ω maximum zener impedance at 5 mA test current. It provides three isolated, low-leakage (0.5 µA @ 6 V) voltage reference or clamping paths in one footprint, commonly used in precision analog supply rail stabilization and overvoltage protection circuits for portable instrumentation.

For engineers reviewing the BZX84C9V1TS-7-F datasheet, BZX84C9V1TS-7-F pinout, BZX84C9V1TS-7-F application, or BZX84C9V1TS-7-F equivalent, key selection criteria include zener voltage accuracy at 5 mA, thermal resistance (625 °C/W), reverse leakage at VR = 6.0 V, temperature coefficient (3.8 to 7.0 mV/°C), and SOT-363 terminal layout compatibility with high-density PCB routing.

Technical Context

This device integrates three independent Zener diodes sharing only mechanical packaging-not electrical connection-enabling simultaneous regulation of multiple voltage rails or redundant clamping paths. Each element exhibits sharp breakdown knee and stable dynamic impedance below 15 Ω at IZT = 5 mA, with minimal temperature drift across –65 °C to +150 °C operating range.

Designed for low-power signal conditioning and ESD-tolerant interface protection, it supports DC biasing and transient suppression without external series resistors in low-current (<10 mA) applications. Its 0.006 g mass and UL 94V-0 molded plastic case meet stringent requirements for handheld and automotive body electronics.

FAQ

What is the maximum reverse current at 6.0 V for BZX84C9V1TS-7-F?

The maximum reverse current is 0.5 µA at VR = 6.0 V, measured at TA = 25 °C. This low leakage ensures minimal loading on high-impedance sensor outputs and reference dividers, preserving signal integrity in precision analog circuits without requiring additional buffering stages.

Can BZX84C9V1TS-7-F be used in parallel configurations?

No-parallel connection of Zener elements is not recommended due to mismatched breakdown characteristics between individual diodes. Each of the three elements must be used independently with appropriate series limiting resistors to ensure current sharing remains within 200 mW total package dissipation.

Is the SOT-363 package compatible with standard reflow profiles?

Yes-the SOT-363 package is qualified for lead-free reflow per JEDEC J-STD-020D, with peak temperature up to 260 °C and moisture sensitivity level 1, eliminating bake requirements prior to assembly and supporting high-yield automated placement in Class II and III production lines.

How does temperature affect the 9.1 V zener voltage?

The temperature coefficient ranges from +3.8 to +7.0 mV/°C at IZT = 5 mA, indicating a predictable positive drift. At +85 °C, the nominal 9.1 V shifts by +0.36 to +0.63 V, which must be accounted for in wide-temperature-range reference designs using this device.
