Product details
Overview
BZX84-B3V6,215 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, designed for precision low-power voltage reference and clamping in space-constrained PCBs. It delivers a nominal 3.6 V breakdown voltage at 5 mA, with 90 Ω typical differential resistance, 5 μA max reverse current at 1 V, and operates across –55 °C to +150 °C ambient.
For engineers reviewing the BZX84-B3V6,215 datasheet, BZX84-B3V6,215 pinout, BZX84-B3V6,215 application, or BZX84-B3V6,215 equivalent, this part supports stable biasing in analog sensor interfaces, overvoltage protection in microcontroller I/O rails, and reference generation in low-current power management circuits.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable voltage across its terminals under varying load and temperature conditions. Its ±2 % tolerance and low 90 Ω dynamic impedance ensure tight regulation accuracy for signal conditioning and reference applications.
The device features non-repetitive peak reverse power dissipation up to 40 W (100 μs pulse), junction-to-ambient thermal resistance of 500 K/W on FR4 PCB, and a negative temperature coefficient of –3.5 mV/K at 5 mA - enabling predictable drift compensation in temperature-sensitive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 3.53 V to 3.67 V at IZ = 5 mA - defines regulated output voltage window under standard test conditions |
| Differential Resistance (rdif) | 90 Ω typical - determines small-signal voltage variation per mA change in Zener current |
| Reverse Current (IR) | ≤5 μA at VR = 1 V - ensures minimal leakage in standby or high-impedance bias networks |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 μs pulses - enables transient overvoltage suppression without damage |
| Junction Temperature (Tj) | –55 °C to +150 °C - supports operation in industrial and automotive-adjacent environments |
| Package | SOT23 (TO-236AB) - surface-mount 3-pin footprint compatible with automated reflow assembly |
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 terminations for lead-free reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential node in reverse-bias configuration; carries forward current during fault or startup |
| 2 | Not Connected (n.c.) | Internal die bond wire stub; electrically isolated - must remain unconnected on PCB |
| 3 | Cathode (K) | Connected to higher-potential node; defines Zener voltage drop direction and polarity in regulation path |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % voltage tolerance | Enables tighter regulation than ±5 % variants (BZX84-C series), reducing calibration overhead in precision references |
| Low 90 Ω differential resistance | Minimizes output voltage shift under load variations - critical for stable biasing of op-amps and ADC references |
| 40 W non-repetitive surge rating | Withstands ESD and line transients without degradation when used with appropriate series limiting resistor |
| 150 °C max junction temperature | Supports reliable operation in thermally dense layouts near power converters or processors |
| SOT23 package compatibility | Matches industry-standard pick-and-place tooling and reflow profiles - no special assembly requirements |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller I/O Protection |

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 MMBZ5226BS-7-F | 3.6 V ±5 %, 200 mW Ptot, 100 Ω rdif | Looser tolerance and higher impedance reduce regulation accuracy in precision analog paths | Select when cost sensitivity outweighs voltage stability requirements and board space allows minor layout adjustment |
| Vishay BZX84-C3V6-7-F | 3.6 V ±5 %, same SOT23 package, 90 Ω rdif, 5 μA IR | Higher tolerance increases initial calibration burden but matches thermal and surge specs | Choose for non-critical biasing where ±5 % is acceptable and legacy BOM alignment is prioritized |
Compared with BZX84-B3V6,215, the MMBZ5226BS-7-F trades regulation precision for broader availability, while the BZX84-C3V6-7-F retains identical thermal and dynamic behavior but sacrifices 3× voltage accuracy - making the B-series optimal for designs requiring ±2 % stability without redesign.

FAQ
What is the maximum continuous Zener current for BZX84-B3V6,215?
The absolute maximum forward current is 200 mA per datasheet limiting values, but continuous Zener operation is constrained by power dissipation. At 25 °C ambient on FR4 PCB, 250 mW total power limits IZ to approximately 69 mA (250 mW ÷ 3.6 V). Derating is required above 25 °C using the 500 K/W thermal resistance.
Can BZX84-B3V6,215 replace BZX84-A3V6 in existing designs?
Yes, but with measurable impact on regulation accuracy: the A-series offers ±1 % tolerance (3.56–3.64 V) versus B-series ±2 % (3.53–3.67 V). Differential resistance and thermal characteristics are identical. Designers should verify whether the additional 14 mV worst-case voltage spread affects system-level calibration or margin.
Is pin 2 truly unused, or does it serve a mechanical function?
Pin 2 is electrically not connected (n.c.) per Nexperia's official pinning diagram and internal construction. It serves only as a mechanical support stub for die bonding and provides no electrical functionality - PCB footprints must leave it unconnected and un-routed to avoid unintended shorts or parasitic coupling.
How does temperature affect the 3.6 V regulation point?
The BZX84-B3V6,215 has a temperature coefficient of –3.5 mV/K at 5 mA, meaning its Zener voltage decreases by ~3.5 mV per 1 K rise in junction temperature. Over a 100 °C range (25 °C to 125 °C), this results in ~350 mV total drift - a key consideration when designing for wide-temperature operation without external compensation.
