Diodes Incorporated BZX84C5V6S-7-F

Overview

BZX84C5V6S-7-F from Diodes Incorporated is a dual 200 mW surface-mount Zener diode in SOT-363 package, rated for nominal zener voltage 5.6 V (min 5.2 V, max 6.0 V) at 5 mA test current, with zener impedance of 40 Ω at I_ZT and 400 Ω at I_ZK, used for precision voltage regulation and reference in low-power analog circuits.

For engineers reviewing the BZX84C5V6S-7-F datasheet, BZX84C5V6S-7-F pinout, BZX84C5V6S-7-F application, or BZX84C5V6S-7-F equivalent, key selection criteria include zener voltage tolerance (±0.4 V), low dynamic impedance, thermal resistance (625 °C/W), RoHS-compliant lead-free plating, and SOT-363 footprint compatibility with space-constrained PCB layouts.

Technical Context

This dual Zener diode integrates two independent 5.6 V zener elements in a single ultra-small SOT-363 package, sharing no internal connection - each anode-cathode pair operates independently. It uses planar die construction for stable breakdown characteristics and low leakage.

Designed for DC voltage regulation and reference, it delivers specified zener voltage at 5 mA test current with temperature coefficient of –2.0 to –2.5 mV/°C, and supports reverse current as low as 1.0 µA at 2.0 V, enabling low-quiescent monitoring functions.

FAQ

What is the maximum reverse voltage (V_R) this Zener can withstand before breakdown?

The BZX84C5V6S-7-F has a nominal zener voltage of 5.6 V, with guaranteed breakdown occurring between 5.2 V and 6.0 V at 5 mA test current. Its maximum reverse voltage prior to conduction is not defined as a standalone parameter - instead, it begins regulating at V_Z; operation below 5.2 V results in <1.0 µA leakage at 2.0 V, per datasheet specifications.

Can both Zener elements be used simultaneously with shared cathodes or anodes?

No - pins 1 and 6 are NC, and the two Zener elements (C1/A1 and C2/A2) are fully isolated. There is no internal connection between them. Each must be biased independently; shared cathode or anode configurations require external wiring and are not supported by the internal structure.

Is this part suitable for use in automotive under-hood applications?

It operates across –65 °C to +150 °C, meeting extended temperature requirements, but is not AEC-Q200 qualified. For non-safety-critical under-hood subsystems (e.g., cabin sensors or lighting controls), it may be used with appropriate system-level validation; however, AEC-Q200-qualified alternatives are recommended for safety-relevant modules.

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

The SOT-363 has higher thermal resistance (625 °C/W vs. ~300–400 °C/W for typical SOT-23 Zeners) due to its smaller pad area and dual-die layout. To maintain 200 mW dissipation, it requires strict adherence to Diodes' recommended FR4 pad layout (AP02001) and avoids thermal vias under NC pins, which are not electrically connected.
