Product details
Overview
BZX84-C5V1/DG,215 from Nexperia is a 5.1 V ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 250 mW total power dissipation at 25 °C ambient, with 480 Ω max differential resistance at 5 mA and 2 µA max reverse current at 3.8 V, used for precision low-power voltage reference and overvoltage clamping in sensor signal conditioning circuits.
For engineers reviewing the BZX84-C5V1/DG,215 datasheet, BZX84-C5V1/DG,215 pinout, BZX84-C5V1/DG,215 application, or BZX84-C5V1/DG,215 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (330 K/W junction-to-solder-point), non-repetitive peak reverse power (40 W), and cathode-anode polarity confirmation for PCB layout verification.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable output voltage across its cathode–anode terminals when reverse-biased above its nominal 5.1 V breakdown threshold. It exhibits a positive temperature coefficient of +1.2 mV/K at 5 mA, enabling predictable drift compensation in temperature-sensitive references.
Its SOT23 package features three terminals - anode (Pin 1), not-connected (Pin 2), and cathode (Pin 3) - with Pin 2 electrically isolated to reduce parasitic capacitance and improve high-frequency regulation stability in compact DC-DC feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.8 V to 5.4 V at IZ = 5 mA - defines usable regulation window under standard test conditions |
| Differential Resistance (rdif) | ≤480 Ω - determines output impedance and load regulation error sensitivity |
| Reverse Current (IR) | ≤2 µA at VR = 3.8 V - ensures low leakage in standby or battery-powered monitoring nodes |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling without derating |
| Non-repetitive Peak Reverse Power | 40 W for tp = 100 µs - supports transient surge suppression in ESD-critical I/O protection |
| Thermal Resistance (Rth(j-sp)) | 330 K/W - quantifies junction-to-solder-point heat transfer efficiency for thermal design margining |
| Temperature Coefficient (SZ) | +1.2 mV/K at IZ = 5 mA - enables predictable voltage drift modeling across –55 °C to +150 °C operating range |
Pinout & Package
The BZX84-C5V1/DG,215 is housed in a plastic SOT23 (TO-236AB) surface-mount package with standardized 3-lead footprint, 1.9 mm × 1.1 mm body size, and 0.95 mm height per Nexperia package outline Fig. 11.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Forward current entry point; connected to lower-potential node in shunt regulation configuration |
| 2 | Not Connected | Electrically isolated terminal; no internal bond wire; reduces stray capacitance and simplifies layout routing |
| 3 | Cathode | Reverse-bias voltage reference node; tied to regulated output or feedback divider in voltage reference designs |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is secondary to component count reduction |
| 250 mW power rating at 25 °C | Supports continuous operation in low-current analog front-ends without heatsinking or airflow |
| 40 W non-repetitive peak power | Provides robust transient immunity against ESD events up to IEC 61000-4-2 Level 4 (8 kV contact) |
| SOT23 package with NC pin | Minimizes board area while isolating unused terminal to suppress parasitic coupling in RF-adjacent layouts |
| +1.2 mV/K temperature coefficient | Allows predictable voltage shift compensation in industrial temperature ranges without external thermistors |
Applications
| Industrial Sensor Signal Conditioning | USB Port Overvoltage Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5221BS-7-F | Same 5.1 V nominal, ±5 % tolerance, but rated for 350 mW Ptot and uses SOT-23 package with standard pin 1–2–3 anode–cathode–NC mapping | Higher power rating allows use in higher-current bias networks; identical thermal resistance (330 K/W) | Select when >250 mW continuous dissipation is required without changing PCB layout |
| Vishay BZX84-C5V1-E3-08 | Identical 5.1 V ±5 % spec and SOT23 package, but marked with "Z2%" code and qualified to AEC-Q200 Grade 3 (–40 °C to +125 °C) | Approved for automotive body electronics; same electrical specs but extended reliability validation | Select for automotive-grade designs requiring qualification evidence beyond industrial temperature range |
Compared with MMBZ5221BS-7-F, BZX84-C5V1/DG,215 offers tighter production traceability via Nexperia's DG marking and optimized thermal path to solder point; versus BZX84-C5V1-E3-08, it lacks AEC-Q200 certification but provides identical regulation performance at lower unit cost for industrial applications.

FAQ
What is the maximum continuous forward current rating for BZX84-C5V1/DG,215?
The device is not rated for continuous forward conduction; its absolute maximum forward current is 200 mA per limiting values Table 5, but typical operation occurs in reverse-bias regulation mode. Forward voltage is specified at 10 mA pulse (≤100 µs), reaching ≤0.9 V - intended only for brief testing or fault-condition analysis, not steady-state use.
Does Pin 2 have any internal connection or function?
No - Pin 2 is explicitly designated "not connected" in Nexperia's pinning information (Table 2). It has no internal bond wire or silicon connection and serves solely as a mechanical lead for package symmetry and pick-and-place stability; it must remain unconnected in circuit layout.
How does the +1.2 mV/K temperature coefficient affect long-term voltage stability?
At 5 mA Zener current, the +1.2 mV/K coefficient means the breakdown voltage increases by 1.2 mV per degree Celsius rise in junction temperature. Over a 100 °C range (–25 °C to +75 °C), this yields a total shift of +120 mV - a +2.35 % deviation from 5.1 V nominal - which must be factored into system-level accuracy budgets for precision references.
Can BZX84-C5V1/DG,215 be used in automotive applications?
No - per Nexperia's revision history (Section 13), the BZX84 series was changed to non-automotive qualification in Rev. 7 (2023). It lacks AEC-Q200 stress testing and automotive-grade process controls; for automotive use, select the BZX84-C5V1-Q variant or Vishay's AEC-Q200-qualified BZX84-C5V1-E3-08 instead.
