Product details
Overview
BZX84C5V6W-7-F from Diodes Incorporated is a 5.6 V, 200 mW surface-mount Zener diode in SOT-323 package, rated for 5 mA test current with 40 Ω dynamic impedance and ±2.5 mV/°C temperature coefficient. It provides precision voltage regulation in low-power biasing, reference, and overvoltage protection circuits across industrial and consumer electronics.
For engineers reviewing the BZX84C5V6W-7-F datasheet, BZX84C5V6W-7-F pinout, BZX84C5V6W-7-F application, or BZX84C5V6W-7-F equivalent, key selection criteria include nominal Zener voltage tolerance (±0.4 V), low reverse leakage (≤1.0 µA at 2.0 V), thermal resistance (625 K/W), RoHS-compliant lead-free plating, and SOT-323 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage under varying load and temperature conditions. Its planar die construction ensures consistent Zener characteristics, while the ultra-small SOT-323 package supports compact power management and signal conditioning designs.
It delivers regulated output at 5.6 V with tight 5.2–6.0 V tolerance band at 5 mA, exhibits low 40 Ω impedance at test current, and maintains predictable voltage drift across –65 °C to +125 °C operating range due to its specified –2.0 to +2.5 mV/°C temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, 5.2–6.0 V min/max at IZT = 5 mA - defines stable regulation point for reference circuits |
| Power Dissipation (PD) | 200 mW - limits continuous power handling on FR4 board with recommended pad layout |
| Zener Impedance (ZZT) | 40 Ω at 5 mA - determines output voltage stability under small-signal load variations |
| Reverse Leakage (IR) | ≤1.0 µA at VR = 2.0 V - ensures minimal quiescent current in standby bias networks |
| Temp. Coefficient (αVZ) | –2.0 to +2.5 mV/°C at 5 mA - quantifies voltage drift over industrial temperature range |
| Package | SOT-323 - 2.2 mm × 1.35 mm footprint enabling high-density PCB integration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F | Same 5.6 V nominal, but 350 mW rating and SOT-363 package with dual diodes | Requires dual-diode layout; higher power enables higher surge tolerance | Select when needing redundant clamping or higher PD margin in same footprint family |
| 1SMA5919BT3G | 5.6 V, 1.5 W rating, DO-214AC package - significantly larger and higher power | Used in mains-connected or high-energy transient suppression where 200 mW is insufficient | Select only when thermal design requires >1 W dissipation or legacy through-hole replacement is needed |
Compared with MMBZ5232BS-7-F and 1SMA5919BT3G, BZX84C5V6W-7-F offers optimal balance of size, cost, and precision for low-power reference and clamping-its SOT-323 footprint and tight 5.2–6.0 V tolerance make it preferred for space-limited, battery-operated designs where 200 mW suffices.

FAQ
What is the maximum reverse voltage before breakdown for BZX84C5V6W-7-F?
The nominal Zener voltage is 5.6 V, with guaranteed breakdown occurring between 5.2 V and 6.0 V at 5 mA test current. Below 5.2 V, reverse leakage remains ≤1.0 µA at 2.0 V, confirming no significant conduction outside the specified Zener range.
Can BZX84C5V6W-7-F be used in place of a 5.1 V Zener diode?
No - its 5.6 V nominal rating and 5.2–6.0 V tolerance band differ from 5.1 V devices like BZX84C5V1W. Substituting would shift reference or clamp thresholds by ≥0.5 V, potentially violating system voltage margins or ADC input ranges.
Is the SOT-323 package thermally adequate for continuous 200 mW operation?
Yes, when mounted on FR4 with Diodes Incorporated's recommended pad layout (document AP02001), the 625 K/W junction-to-ambient thermal resistance allows safe operation at 25 °C ambient. Derating applies above 50 °C per Figure 1 in DS30066.
Does BZX84C5V6W-7-F have polarity marking on the device body?
Yes - a cathode band is printed on the top surface adjacent to pin 1 (cathode) per the SOT-323 top-view diagram in DS30066. The marking code "KR3" identifies the 5.6 V variant and appears next to the band.
