Product details
Overview
BZX84-C5V6/DG,215 from Nexperia is a 5.6 V ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 250 mW total power dissipation at 25 °C ambient, with 40 W non-repetitive peak reverse power capability and 1 μA maximum reverse current at 3.36 V. It serves as a precision reference or overvoltage clamp in low-power analog supply rails and sensor bias networks.
For engineers reviewing the BZX84-C5V6/DG,215 datasheet, BZX84-C5V6/DG,215 pinout, BZX84-C5V6/DG,215 application, or BZX84-C5V6/DG,215 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (400 Ω max at IZ = 5 mA), temperature coefficient (+2.5 mV/K), thermal resistance (500 K/W junction-to-ambient), and SOT23 footprint compatibility with automated assembly.
Technical Context
This device operates in reverse-biased Zener breakdown mode to maintain stable DC voltage across its cathode-anode terminals under varying load or input conditions. Its 5.6 V nominal regulation point is specified at 5 mA test current, with differential resistance ≤400 Ω ensuring minimal voltage shift under small-signal current variations.
The diode exhibits a positive temperature coefficient of +2.5 mV/K at IZ = 5 mA, indicating voltage increases linearly with junction temperature - a critical factor in thermally coupled reference designs. Its 1 μA reverse leakage at VR = 3.36 V enables low-quiescent-current operation in battery-powered circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.2 V to 6.0 V at IZ = 5 mA - defines usable regulation range under standard test condition |
| Differential Resistance (rdif) | ≤400 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | ≤1 μA at VR = 3.36 V - ensures minimal standby power loss in clamping applications |
| Temperature Coefficient (SZ) | +2.5 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling under standard mounting |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp ≤ 100 μs - supports transient surge suppression without failure |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - defines conduction threshold when used in forward-biased protection paths |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount plastic package with 3 leads, 1.3 mm height, 2.9 mm × 1.3 mm footprint, and standard reflow-compatible solder pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential node in Zener configuration; forward conduction path entry |
| 2 | Not Connected (n.c.) | Internally unconnected lead; must remain floating - no PCB trace or thermal pad connection |
| 3 | Cathode (K) | Connected to regulated output node; primary current return path during reverse breakdown |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is not required, e.g., power rail supervision |
| 250 mW steady-state power rating | Supports continuous regulation in sub-10 mA load applications without heatsinking on standard FR4 PCB |
| 40 W pulse power capability | Allows transient overvoltage clamping up to 40 W for 100 μs without degradation or failure |
| SOT23 package compatibility | Enables high-density placement and automated pick-and-place assembly in space-constrained consumer and industrial PCBs |
| +2.5 mV/K temperature coefficient | Provides predictable, linear voltage drift for temperature-compensated reference designs using complementary devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F (Diodes Inc.) | 5.6 V ±5 %, 225 mW Ptot, 300 Ω rdif at 20 mA - lower power rating and higher test current | Less suitable for sustained 5 mA regulation; better for pulsed reference use | Select when lower-cost dual-diode package or tighter batch consistency is prioritized over thermal margin |
| BZX84-C5V6-7-F (Diodes Inc.) | 5.6 V ±5 %, 300 mW Ptot, 400 Ω rdif at 5 mA - same regulation spec but higher power rating | Acceptable in identical footprints; requires verification of thermal derating above 25 °C | Choose for extended ambient temperature operation up to +105 °C with improved safety margin |
Compared with BZX84-C5V6/DG,215, MMBZ5232BS-7-F offers lower thermal mass and tighter lot-to-lot VZ distribution but reduced steady-state power headroom, while BZX84-C5V6-7-F provides higher continuous dissipation at identical Zener characteristics - enabling longer-duration regulation under elevated ambient conditions.

FAQ
What is the maximum continuous Zener current for BZX84-C5V6/DG,215 at 70 °C ambient?
At 70 °C ambient, derating applies: Ptot = 250 mW × (1 − (70 − 25)/150) = 175 mW. With VZ ≈ 5.6 V, maximum continuous Zener current is ~31 mA. This assumes FR4 PCB mounting with single-sided copper and standard footprint per datasheet conditions.
Can BZX84-C5V6/DG,215 be used in forward conduction mode?
Yes - its forward voltage is ≤0.9 V at 10 mA, making it suitable as a low-drop rectifier or polarity protection diode. However, its 200 mA absolute maximum forward current and lack of fast recovery optimization limit use to low-frequency, low-dV/dt applications.
Is Pin 2 electrically isolated or internally bonded?
Pin 2 is explicitly marked "n.c." (not connected) in the official Nexperia datasheet and confirmed in the simplified outline diagram. It is internally unconnected and must remain floating on the PCB - no solder mask opening, thermal pad, or trace connection is permitted.
How does the +2.5 mV/K temperature coefficient affect long-term stability in a 0–70 °C operating range?
Over 0–70 °C, the Zener voltage shifts by +2.5 mV/K × 70 K = +175 mV, resulting in a total range of 5.375 V to 5.775 V. This ±3.5 % drift is acceptable for non-critical biasing but requires compensation in precision references via matched TC components or calibration.
