Product details
Overview
BZX84-A7V5,215 from Nexperia is a ±1 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, designed for precision low-power voltage reference and clamping in biasing, protection, and regulation circuits. It delivers 7.5 V nominal breakdown voltage at 5 mA, with 80 Ω max differential resistance, 1 μA max reverse current at 5.3 V, and 2.5 mV/K temperature coefficient - deployed in power supply feedback loops and analog sensor signal conditioning.
For engineers reviewing the BZX84-A7V5,215 datasheet, BZX84-A7V5,215 pinout, BZX84-A7V5,215 application, or BZX84-A7V5,215 equivalent, this page provides verified electrical parameters, thermal behavior under PCB-mount conditions, SOT23 terminal mapping, real-world use cases in voltage stabilization and overvoltage protection, and validated alternative parts with documented tolerance and temperature coefficient differences.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable DC voltage across its terminals under varying load or input conditions. Its ±1 % tolerance and low 80 Ω dynamic impedance ensure tight regulation accuracy in feedback networks of linear regulators and op-amp references.
Thermal performance is defined by junction-to-ambient resistance of 500 K/W on FR4 PCB and junction-to-solder-point resistance of 330 K/W, enabling reliable operation up to 150 °C junction temperature with 250 mW steady-state dissipation and 40 W non-repetitive surge capability (100 μs pulse).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 7.42 V to 7.58 V at IZ = 5 mA - ensures ±1 % output stability in precision reference paths |
| Differential Resistance (rdif) | ≤80 Ω at IZ = 5 mA - minimizes output voltage variation under load current changes |
| Reverse Current (IR) | ≤1 μA at VR = 5.3 V - guarantees low leakage in high-impedance sensing and standby circuits |
| Temperature Coefficient (SZ) | +2.5 mV/K at IZ = 5 mA - enables predictable drift compensation in temperature-sensitive designs |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - defines maximum continuous DC power handling in standard layout |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs - supports transient overvoltage suppression without failure |
| Junction Temperature (Tj) | −55 °C to +150 °C - validates operation across industrial ambient ranges |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; compact 2.9 mm × 1.3 mm footprint, 1.1 mm height, and tin-plated copper terminations compatible with reflow and wave soldering per IPC-7095.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in Zener regulation configuration |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating - no PCB trace or component connection |
| 3 | Cathode (K) | Reverse-biased terminal; connects to higher-potential node and serves as regulated output reference point |
Key Features
| Feature | Design Value |
|---|---|
| ±1 % voltage tolerance | Enables direct replacement in circuits requiring tight reference accuracy without trimming resistors |
| Low 80 Ω dynamic impedance | Maintains <±10 mV output shift across 1–10 mA load current variation in feedback loops |
| +2.5 mV/K tempco | Allows predictable offset correction in temperature-compensated voltage references |
| 40 W surge rating (100 μs) | Clamps ESD and inductive spikes in I/O protection without degradation |
| 250 mW steady-state dissipation | Supports continuous regulation in space-constrained SMT designs without heatsinking |
Applications
| Power Supply Feedback Reference | Overvoltage Protection Clamp |
|---|---|
|
Use Scenario: Stabilizing output voltage in adjustable LDO or switching regulator feedback divider. IC Role / Device Role / Timing Role: Provides precise 7.5 V reference point for error amplifier comparison. Use Value: ±1 % tolerance eliminates need for external calibration; low rdif prevents loop instability under load transients. |
Use Scenario: Protecting microcontroller GPIO pins from 12 V rail coupling during hot-swap events. IC Role / Device Role / Timing Role: Shunts excess voltage above 7.5 V to ground before IC damage threshold is exceeded. Use Value: 40 W peak power rating absorbs 100 μs surges; 1 μA leakage avoids signal distortion in high-Z inputs. |
| Sensor Signal Conditioning | ADC Input Voltage Limiting |
|
Use Scenario: Biasing bridge-based pressure sensor with stable excitation voltage. IC Role / Device Role / Timing Role: Supplies regulated 7.5 V excitation to Wheatstone bridge while rejecting supply ripple. Use Value: +2.5 mV/K tempco matches typical silicon strain gauge drift, reducing net system error. |
Use Scenario: Preventing ADC input overload when interfacing with 10 V industrial sensors. IC Role / Device Role / Timing Role: Clamps input to 7.5 V + VF (≈0.9 V) to stay within 5.5 V absolute max rating. Use Value: 0.9 V forward drop at 10 mA ensures safe clamping at 8.4 V, well below destructive thresholds. |
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 MMBZ5227BS-7-F | 7.5 V ±5 % tolerance; 100 Ω rdif; −2 mV/K tempco | Higher tolerance and impedance reduce accuracy in precision feedback; negative tempco opposes sensor drift | Select only where cost sensitivity outweighs regulation accuracy and thermal tracking needs |
| Vishay BZX84-C7V5-TP | 7.5 V ±5 % tolerance; 150 Ω rdif; 5.3 mV/K tempco | Loose tolerance increases reference error; higher tempco degrades stability in wide-temperature environments | Acceptable for non-critical clamping where 7.5 V is nominal but not tightly enforced |
Compared with BZX84-A7V5,215, the MMBZ5227BS-7-F offers lower cost but sacrifices ±1 % accuracy and thermal predictability, while the BZX84-C7V5-TP trades tighter manufacturing control for broader tolerance - making the A-grade part essential for closed-loop regulation where <±10 mV deviation is unacceptable.

FAQ
What is the maximum continuous forward current for BZX84-A7V5,215?
The device is rated for 200 mA maximum forward current per Absolute Maximum Ratings. However, it is operated in reverse breakdown for regulation; forward conduction is limited to brief pulses (e.g., during power-up sequencing), and sustained forward bias exceeds design intent and risks thermal runaway.
Can BZX84-A7V5,215 be used in place of a 7.5 V TL431 shunt regulator?
No - the BZX84-A7V5,215 is a passive two-terminal Zener diode with fixed 7.5 V breakdown, whereas the TL431 is an active three-terminal programmable shunt regulator with adjustable output (2.5 V to 36 V), lower dynamic impedance (~0.2 Ω), and built-in error amplifier. They serve different functional roles and are not interchangeable without circuit redesign.
How does the "n.c." pin (Pin 2) affect PCB layout?
Pin 2 is internally unconnected and must remain electrically isolated on the PCB - no trace, pad, or via should contact it. Including it in a copper pour or routing a signal nearby may cause parasitic capacitance or contamination risk during assembly; best practice is to omit the pad or mask it entirely in the footprint.
Is BZX84-A7V5,215 qualified for automotive applications?
No - per Nexperia's revision history (Rev. 7, Jan 2023), the BZX84 series is explicitly designated as non-automotive qualified. Automotive alternatives (e.g., BZX84-Q series) undergo additional AEC-Q101 stress testing and have separate part numbering; using this part in automotive systems voids warranty and violates functional safety requirements.
