Product details
Overview
BZX84-C5V6/DG/B3:2 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 and 40 W non-repetitive peak reverse power, used for low-power voltage reference and overvoltage protection in signal conditioning and power rail stabilization circuits.
For engineers reviewing the BZX84-C5V6/DG/B3:2 datasheet, BZX84-C5V6/DG/B3:2 pinout, BZX84-C5V6/DG/B3:2 application, or BZX84-C5V6/DG/B3:2 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (400 Ω max at IZ = 5 mA), temperature coefficient (+2.5 mV/K), reverse current (≤1 μA at VR = 4.0 V), and thermal resistance (330 K/W junction-to-solder point).
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 5.6 V at 5 mA test current, exhibiting a positive temperature coefficient of +2.5 mV/K - indicating voltage increases with junction temperature. Its low 400 Ω maximum differential resistance ensures stable regulation under varying load currents.
Designed for surface-mount use on FR4 PCBs with standard SOT23 footprint, it supports pulse operation up to 40 W (tp = 100 μs) and continuous DC dissipation up to 250 mW at Tamb ≤ 25 °C, with thermal resistance from junction to solder point specified at 330 K/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.2 V to 6.0 V at IZ = 5 mA - defines regulation band for precision reference applications |
| Differential Resistance (rdif) | ≤400 Ω - low impedance ensures minimal output voltage shift under load variation |
| Reverse Current (IR) | ≤1 μA at VR = 4.0 V - guarantees low leakage in standby or sensing circuits |
| Temperature Coefficient (SZ) | +2.5 mV/K - predictable positive drift enables compensation in temperature-sensitive designs |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC operating limit on standard PCB |
| Non-repetitive Peak Power (PZSM) | 40 W (tp = 100 μs) - supports transient surge suppression without failure |
| Junction Temperature (Tj) | −55 °C to +150 °C - wide operating range suits industrial and automotive-adjacent environments |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with 1.9 mm × 1.1 mm body, 0.45 mm lead pitch, and standard reflow-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in regulation path |
| 2 | Not Connected (n.c.) | Internal die pad with no electrical connection - must remain unconnected in layout |
| 3 | Cathode (K) | Reverse-biased terminal; connects to higher-potential node and provides regulated output reference |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective regulation where tight voltage accuracy is not critical (e.g., supply rail clamping) |
| 250 mW DC power rating | Supports continuous operation in space-constrained, low-power embedded systems without heatsinking |
| 40 W peak pulse capability | Provides robust ESD and transient overvoltage protection per IEC 61000-4-2 Level 4 |
| SOT23 package compatibility | Ensures drop-in replacement in legacy designs using industry-standard pick-and-place and reflow processes |
| +2.5 mV/K temperature coefficient | Allows predictable voltage drift modeling for ambient-compensated reference circuits |
Applications
| Power Supply Rail Clamping | Signal-Level Voltage Reference |
|---|---|
Use Scenario: Clamp 5 V logic supply against overshoot during hot-plug or load dump events in microcontroller peripherals. IC Role / Device Role / Timing Role: Zener diode functions as shunt regulator, diverting excess current when rail exceeds 5.6 V. Use Value: Prevents latch-up or damage to downstream 5 V tolerant I/O pins without requiring active circuitry. | Use Scenario: Provide stable bias voltage for op-amp comparators in battery-powered sensor interfaces. IC Role / Device Role / Timing Role: Acts as passive reference source with known VZ and predictable TC for threshold setting. Use Value: Delivers <1 μA leakage and <400 Ω dynamic impedance, enabling accurate 5.6 V threshold with minimal quiescent current. |
| Overvoltage Protection Circuit | ADC Input Protection |
Use Scenario: Protect analog front-end inputs from accidental 12 V misconnection in industrial control modules. IC Role / Device Role / Timing Role: Shunt limiter activated above 5.6 V, limiting input voltage to safe level before series resistor. Use Value: Withstands 40 W transient surges (100 μs), absorbing energy that would otherwise damage precision amplifiers. | Use Scenario: Guard 3.3 V ADC inputs against ESD and transient coupling from adjacent high-voltage traces. IC Role / Device Role / Timing Role: Low-capacitance (300 pF) Zener clamps fast transients while maintaining signal integrity below 5.6 V. Use Value: Limits input voltage to ≤5.6 V without distorting sub-μs analog signals due to minimal junction capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5232BS-7-F | Same 5.6 V nominal, ±5 % tolerance, but rated for 225 mW Ptot and 30 W PZSM | Limited surge handling; less suitable for high-energy transient suppression | Select when board-level surge risk is low and tighter thermal budget exists |
| Vishay BZX84-C5V6-TP | Identical electrical specs and SOT23 package, but marked with "TP" suffix and RoHS-compliant matte tin finish | No functional difference; qualified for same industrial applications | Choose for alternate sourcing where Nexperia allocation is constrained |
Compared with MMBZ5232BS-7-F, BZX84-C5V6/DG/B3:2 offers 11 % higher continuous power and 33 % greater surge capacity; versus BZX84-C5V6-TP, it shares identical regulation performance but differs only in traceable manufacturing batch coding and packaging format.

FAQ
What is the maximum continuous forward current for BZX84-C5V6/DG/B3:2?
The device is not rated for continuous forward conduction; its absolute maximum forward current is 200 mA per limiting values table, but forward operation is not its intended function. It is designed exclusively for reverse-bias Zener regulation, and sustained forward bias may cause thermal runaway or parametric shift.
Can BZX84-C5V6/DG/B3:2 be used in place of a 5.1 V Zener diode?
No - its nominal Zener voltage is 5.6 V with a guaranteed range of 5.2 V to 6.0 V at 5 mA, making it unsuitable as a direct substitute for a 5.1 V part. Using it in a 5.1 V reference circuit would result in ~10 % higher output voltage and potential system malfunction.
Is pin 2 electrically connected internally?
No - pin 2 is explicitly designated "n.c." (not connected) in the official pinning diagram and must remain unconnected in PCB layout. Internal bonding wire is omitted; routing or soldering to this pin introduces risk of mechanical stress or unintended parasitic coupling.
Does BZX84-C5V6/DG/B3:2 meet automotive qualification standards?
No - per Nexperia's revision history (Rev. 7, Jan 2023), the BZX84 series is explicitly stated as non-automotive qualified. For automotive applications, Nexperia offers separate -Q qualified variants (e.g., BZX84-C5V6-Q); this part lacks AEC-Q101 testing and is intended for industrial and commercial use only.
