Diodes Incorporated BZX84C6V2TS-7-F

Overview

BZX84C6V2TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 6.2 V (nominal) Zener elements in a single SOT-363 package, rated for 200 mW total power dissipation, 10 Ω typical Zener impedance at 5 mA, and operating across –65 °C to +150 °C - used for precision voltage reference and overvoltage protection in compact DC power rails.

For engineers reviewing the BZX84C6V2TS-7-F datasheet, BZX84C6V2TS-7-F pinout, BZX84C6V2TS-7-F application, or BZX84C6V2TS-7-F equivalent, key selection criteria include zener voltage tolerance (±0.4 V), low dynamic impedance, thermal stability (0.4 mV/°C tempco), and triple-diode isolation for multi-rail clamping without cross-coupling.

Technical Context

This device integrates three independent Zener diodes sharing only mechanical packaging - no internal electrical connection - enabling simultaneous regulation or clamping of three separate signal or supply lines. Each element exhibits sharp reverse breakdown at 6.2 V with 5 mA test current, and maintains stable operation under transient surges up to 150 Ω maximum impedance at knee current (1 mA).

The SOT-363 footprint supports high-density PCB layouts while delivering 625 °C/W junction-to-ambient thermal resistance on FR4 boards. Its RoHS-compliant matte tin plating and halogen-free molding compound meet industrial environmental compliance requirements without sacrificing electrical performance.

Key Specifications

Pinout & Package

SOT-363 package: six-terminal surface-mount plastic case with three anode-cathode pairs arranged as two outer diodes (C1/A1, C3/A3) and one center diode (C2/A2); terminals are solderable per MIL-STD-202 Method 208 and marked per Diodes Inc. layout diagram (C1–C3 cathodes, A1–A3 anodes).

FAQ

What is the maximum reverse current at 4.0 V for BZX84C6V2TS-7-F?

The maximum reverse current (I_R) is 3.0 µA at V_R = 4.0 V, measured at 25 °C ambient. This value reflects leakage behavior below the 5.8 V minimum Zener breakdown threshold and remains stable across the full operating temperature range (–65 °C to +150 °C), supporting low-power standby modes in battery-operated devices.

Can BZX84C6V2TS-7-F be used for bidirectional ESD protection?

No - it is a unidirectional Zener diode array optimized for reverse-bias clamping only. For bidirectional ESD protection, external series resistors and forward-path diodes (e.g., in a TVS + Zener hybrid network) are required. The device's forward voltage is 0.9 V at 10 mA, but its structure lacks symmetric avalanche characteristics for reliable positive-voltage transient handling.

How does the SOT-363 package affect thermal performance compared to SOT-23?

The SOT-363 package has a higher junction-to-ambient thermal resistance (625 °C/W) than typical SOT-23 variants (~400–500 °C/W) due to its smaller pad area and shared thermal mass among three die. However, its 200 mW power rating is validated for FR4 boards using Diodes Inc.'s recommended pad layout (AP02001), ensuring safe operation when layout guidelines are followed.

Is the 6.2 V Zener voltage specified at DC or pulsed conditions?

The 6.2 V nominal Zener voltage is specified under DC test conditions at I_ZT = 5 mA, with pulse duration short enough to limit self-heating (per Note 5). The datasheet confirms this value holds across continuous operation within the 200 mW power limit and thermal derating curve - no separate pulsed specification is defined, as the device is rated for steady-state regulation.
