Product details
Overview
BZX84-C7V5,215 from Nexperia is a ±5 % 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 a nominal 7.5 V breakdown voltage at 5 mA, with 80 Ω differential resistance, 1 μA reverse current at 5.6 V, +2.5 mV/K temperature coefficient, and 150 pF capacitance at 1 MHz.
For engineers reviewing the BZX84-C7V5,215 datasheet, BZX84-C7V5,215 pinout, BZX84-C7V5,215 application, or BZX84-C7V5,215 equivalent, this page provides verified Zener parameters, thermal limits, SOT23 terminal mapping, and direct alternatives for voltage reference design, overvoltage clamping, and analog signal conditioning in industrial control, power supply feedback, and sensor interface circuits.
Technical Context
This Zener diode operates in reverse-biased avalanche mode to maintain stable DC voltage under varying load and temperature conditions. Its ±5 % tolerance (C-grade), 7.0–7.9 V working range at IZ = 5 mA, and +2.5 mV/K positive temperature coefficient enable predictable drift compensation in multi-diode references.
Designed for surface-mount use on FR4 PCBs with single-sided 70 µm copper, it supports pulsed operation up to 40 W (100 µs, square wave) and continuous dissipation of 250 mW at Tamb ≤ 25 °C, with junction temperature limited to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 7.0 V to 7.9 V at IZ = 5 mA - defines usable regulation window for 7.5 V nominal reference |
| Differential Resistance rdif | 80 Ω max - determines output impedance and load regulation error in shunt regulator topologies |
| Reverse Current IR | 1 μA max at VR = 5.6 V - ensures low leakage in high-impedance bias networks |
| Temperature Coefficient SZ | +2.5 mV/K - enables predictable voltage drift tracking for temperature-compensated designs |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard PCB layout |
| Non-repetitive Peak Power | 40 W for 100 µs pulses - supports transient overvoltage suppression without failure |
| Junction-to-Ambient Rth(j-a) | 500 K/W - informs thermal derating requirements for ambient temperatures above 25 °C |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; compact footprint (2.9 mm × 1.3 mm × 1.0 mm) optimized for automated assembly and space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential node in reverse-bias configuration; carries forward current during conduction |
| 2 | Not Connected (n.c.) | Internally unconnected lead - must remain floating; no PCB trace or solder pad required |
| 3 | Cathode (K) | Connected to higher-potential node; defines Zener breakdown polarity and voltage reference point |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % voltage tolerance (C-grade) | Enables cost-effective selection for non-critical regulation where tighter tolerances are unnecessary |
| 250 mW total power dissipation | Supports stable operation in low-current bias networks without heatsinking on standard FR4 PCBs |
| 150 pF diode capacitance at 1 MHz | Limits high-frequency noise coupling in RF-adjacent or fast-switching applications |
| +2.5 mV/K temperature coefficient | Allows predictable voltage shift across -55 °C to +150 °C ambient range for thermal modeling |
| 40 W non-repetitive peak power rating | Provides robust transient suppression capability against ESD or surge events in input protection stages |
Applications
| Power Supply Feedback | Sensor Bias Reference |
|---|---|
Use Scenario: Stabilizing output voltage in isolated flyback or buck converter feedback loops using optocoupler-coupled TL431 alternatives. IC Role / Device Role / Timing Role: Shunt voltage reference providing precise 7.5 V threshold for error amplifier comparison. Use Value: Maintains ±5 % output regulation accuracy across line/load variations without active IC overhead. |
Use Scenario: Supplying stable excitation voltage to resistive temperature detectors (RTDs) or bridge-based pressure sensors. IC Role / Device Role / Timing Role: Low-noise, low-drift DC bias source replacing higher-cost precision references in analog front-ends. Use Value: Delivers <1 μA leakage and +2.5 mV/K drift for sub-0.1 % full-scale measurement stability over industrial temperature range. |
| Overvoltage Clamp | Logic-Level Translation |
Use Scenario: Protecting microcontroller GPIO pins or ADC inputs from transient surges exceeding 7.5 V. IC Role / Device Role / Timing Role: Fast-acting crowbar element diverting excess energy to ground when reverse voltage exceeds VZ. Use Value: Limits clamp response time to <10 ns with 40 W pulse handling, preventing latch-up or damage in 3.3 V/5 V systems. |
Use Scenario: Level-shifting 3.3 V logic signals to 7.5 V interface rails in mixed-voltage digital subsystems. IC Role / Device Role / Timing Role: Passive bidirectional translator using forward conduction (0.9 V drop) and reverse breakdown (7.5 V clamp).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5236BS-7-F | 7.5 V ±5 %, 225 mW Ptot, 100 Ω rdif, -2 mV/K tempco | Negative tempco requires opposite drift compensation; lower power rating reduces margin in warm environments | Select when negative tempco aligns with complementary diode stacking or legacy BOM compatibility is required |
| Vishay NZX7V5B,113 | 7.5 V ±2 %, 500 mW Ptot, 70 Ω rdif, +2.0 mV/K tempco, DO-35 axial package | Higher power and tighter tolerance suit higher-current references; through-hole mounting limits SMT scalability | Choose for prototyping or high-reliability linear supplies where axial packaging and 2 % tolerance justify manual assembly |
Compared with MMBZ5236BS-7-F, BZX84-C7V5,215 offers superior thermal resistance control in SMT layouts and more predictable positive drift; versus NZX7V5B,113, it trades 2 % tolerance and 500 mW rating for SOT23 miniaturization and automated manufacturability.

FAQ
What is the maximum continuous forward current for BZX84-C7V5,215?
The absolute maximum forward current is 200 mA per the limiting values table. However, sustained forward conduction is not its intended operating mode; typical forward voltage is 0.9 V at 10 mA, and continuous forward bias should be avoided to prevent degradation of Zener characteristics and thermal overstress.
Can BZX84-C7V5,215 be used in parallel for higher power dissipation?
No - Zener diodes exhibit manufacturing spread in breakdown voltage, causing current hogging and thermal runaway when paralleled. For higher power, use a single higher-rated device like the 500 mW NZX7V5B or implement active regulation with a transistor pass element.
How does the "215" suffix in BZX84-C7V5,215 affect specifications?
The "215" is a Nexperia internal package variant code indicating tape-and-reel packaging in 3,000-unit reels with standard SOT23 orientation and moisture sensitivity level (MSL) 1 - it does not alter electrical or thermal specifications, which are fully defined by the BZX84-C7V5 base type.
Is BZX84-C7V5,215 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-grade alternatives include the BZX84-Q series (e.g., BZX84-C7V5-Q), which undergo extended temperature testing and AEC-Q200 qualification.
