Product details
Overview
BZX84-C36,215 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 36 V nominal breakdown voltage at 2 mA, 350 Ω maximum differential resistance, and 90 µA reverse current at 28.8 V. It delivers stable reference voltage in low-power power supply regulation and overvoltage protection circuits for industrial sensor interfaces and embedded microcontroller I/O clamping.
For engineers reviewing the BZX84-C36,215 datasheet, BZX84-C36,215 pinout, BZX84-C36,215 application, or BZX84-C36,215 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 SOT23 footprint compatibility with automated PCB assembly.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 36 V reference across its cathode–anode terminals under controlled current conditions. Its temperature coefficient of +0.05 mV/K at IZ = 2 mA ensures minimal drift over ambient range (−55 °C to +150 °C).
The device supports transient suppression via 40 W non-repetitive peak reverse power dissipation (tp = 100 µs), while its 250 mW total power rating at Tamb ≤ 25 °C defines steady-state thermal limits on FR4 PCBs with standard single-sided copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34.0 V to 38.0 V at IZ = 2 mA - defines usable regulation window for precision reference design |
| Differential Resistance (rdif) | ≤350 Ω - determines output impedance and load regulation error under varying current |
| Reverse Current (IR) | ≤90 µA at VR = 28.8 V - specifies leakage level below breakdown, critical for low-power standby circuits |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - enables short-duration surge clamping without thermal runaway |
| Junction-to-Solder-Point Rth | 330 K/W - quantifies thermal path efficiency from die to PCB copper, guiding layout for reliability |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with 1.9 mm × 1.3 mm footprint and 1.1 mm height; optimized for reflow and wave soldering per Nexperia's recommended land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in regulation circuit |
| 2 | Not Connected (n.c.) | Internal die pad with no electrical connection; must remain unconnected on PCB |
| 3 | Cathode (K) | Reverse-biased terminal; connects to higher-potential node and serves as voltage reference output |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage reference where tight regulation is not required, e.g., supply rail monitoring |
| 250 mW total power rating | Supports continuous operation in space-constrained consumer and industrial PCBs without heatsinking |
| 40 W non-repetitive peak power | Provides transient overvoltage protection for I/O lines without external TVS cascading |
| SOT23 package compatibility | Ensures drop-in placement in high-volume automated assembly lines using standard pick-and-place tooling |
| −55 °C to +150 °C operating range | Validates use in extended-temperature environments such as automotive under-hood modules (non-automotive qualified) |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller I/O Clamping |
|---|---|
|
Use Scenario: Stabilizing reference voltage for analog front-end amplifiers in 4–20 mA loop-powered sensors. IC Role / Device Role / Timing Role: Zener diode provides fixed 36 V rail for op-amp biasing and ADC reference scaling. Use Value: Maintains <±1 % output stability over −40 °C to +85 °C ambient, reducing calibration frequency. |
Use Scenario: Protecting GPIO pins of ARM Cortex-M microcontrollers against ESD-induced overvoltage. IC Role / Device Role / Timing Role: Acts as bidirectional clamp between I/O line and 3.3 V rail, sinking transients above 36 V. Use Value: Limits pin voltage to safe levels during 8 kV HBM ESD events without degrading signal integrity. |
| Low-Power AC/DC Auxiliary Supply | Programmable Logic Controller Input Protection |
|
Use Scenario: Regulating unregulated 48 V DC auxiliary supply down to 36 V for isolated gate driver biasing. IC Role / Device Role / Timing Role: Functions as shunt regulator in series with current-limiting resistor to deliver stable bias voltage. Use Value: Delivers 5 mA regulated current with <2 % line regulation across 45–52 V input variation. |
Use Scenario: Guarding 24 V digital input channels in PLC backplanes against field-wiring surges. IC Role / Device Role / Timing Role: Placed between input terminal and ground to clamp induced transients before optocoupler input. Use Value: Withstands 1 kV/µs fast-rising surges per IEC 61000-4-4, preventing false triggering. |
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 MMBZ5226BS-7-F | 36 V nominal, ±5 %, 200 mW Ptot, SOT23 package | Lower power rating reduces surge handling margin; requires tighter current limiting | Select when board-level power budget is constrained below 200 mW and thermal mass is limited |
| Vishay BZX84-C36-TP | 36 V nominal, ±5 %, 300 mW Ptot, same SOT23 footprint | Higher power rating allows greater steady-state current but increases thermal footprint demand | Prefer for designs requiring >250 mW continuous dissipation or extended ambient temperature margins |
Compared with BZX84-C36,215, the ON Semiconductor part trades 50 mW power headroom for tighter supply-chain availability in North America, while the Vishay part offers enhanced thermal robustness at the cost of higher junction temperature rise under identical PCB layout.

FAQ
What is the maximum continuous forward current for BZX84-C36,215?
The absolute maximum forward current is 200 mA per the limiting values table. However, this rating applies only under pulsed conditions with strict duty cycle control. In normal Zener operation, the device is reverse-biased; forward conduction is avoided except during transient events or test conditions.
Can BZX84-C36,215 be used in automotive applications?
No - this part is explicitly marked as non-automotive qualified per Nexperia's revision history. It lacks AEC-Q101 qualification, automotive-grade screening, and guaranteed performance across −40 °C to +125 °C extended temperature ranges required for automotive ECUs or body electronics.
How does the "215" suffix in BZX84-C36,215 relate to marking or packaging?
The "215" denotes the specific tape-and-reel packaging variant per Nexperia's ordering system: it indicates 3,000 units per reel in 8 mm carrier tape with embossed pockets, compatible with standard SMT feeders. The device marking on the package is "%T7", per Table 4 of the datasheet.
Is pin 2 truly unconnected, or can it be grounded for thermal improvement?
Pin 2 is internally not connected - no bond wire or die attachment exists. Grounding it provides no thermal benefit and risks solder bridging or unintended parasitic coupling. Nexperia's thermal characterization (Rth(j-sp)) assumes pin 2 is left floating, and PCB layout must follow the specified solder land pattern without modifying pin 2 connectivity.
