Product details
Overview
BZX84-A5V6,215 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 signal conditioning and power rail stabilization circuits. It delivers 5.6 V nominal breakdown voltage at 5 mA, with 400 Ω max differential resistance, 1 µA max reverse current at 4.2 V, and -2.0 to +2.5 mV/K temperature coefficient - enabling stable operation in battery-powered sensor interfaces and microcontroller reset circuits.
For engineers reviewing the BZX84-A5V6,215 datasheet, BZX84-A5V6,215 pinout, BZX84-A5V6,215 application, or BZX84-A5V6,215 equivalent, key selection considerations include its ±1 % VZ tolerance, 250 mW total power dissipation at 25 °C ambient, non-repetitive 40 W surge capability, and SOT23-compatible thermal resistance of 330 K/W to solder point.
Technical Context
This device operates as a two-terminal shunt regulator, maintaining a stable 5.6 V reference by conducting reverse current above its specified Zener knee voltage. Its low 1 µA reverse leakage at VR = 4.2 V ensures minimal standby power draw in always-on monitoring circuits.
The ±1 % tolerance grade (denoted by "A" suffix) and tightly controlled -2.0 to +2.5 mV/K temperature coefficient enable predictable regulation across -55 °C to +150 °C ambient range, supporting industrial-grade analog front-ends where drift-critical biasing is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 5.6 V at IZ = 5 mA - precise reference voltage for analog sensing and MCU reset threshold generation |
| Tolerance | ±1 % - enables high-accuracy voltage supervision without external trimming |
| rdif (max) | 400 Ω - limits output impedance variation under load changes, critical for stable feedback in LDO pre-regulators |
| IR (max) | 1 µA at VR = 4.2 V - ensures negligible quiescent current in low-power wake-up circuits |
| Ptot | 250 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling on standard FR4 PCB |
| PZSM | 40 W non-repetitive peak - supports transient overvoltage clamping during ESD or inductive switching events |
| SZ | -2.0 to +2.5 mV/K - quantifies voltage drift per degree Celsius, enabling thermal error budgeting in precision references |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount plastic package with 3 leads, 1.9 mm × 1.3 mm footprint, 1.1 mm height, and standard reflow-compatible pad layout (0.6 mm solder land width).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Connected to lower-potential node (e.g., ground or supply return); reverse-biased operation requires cathode at higher potential |
| 2 (n.c.) | No connection | Internally unconnected; must remain floating - no PCB trace or thermal pad should tie this pin |
| 3 (Cathode) | Cathode connection | Connected to regulated voltage node; carries full Zener current during regulation; primary thermal path to PCB via solder point |
Key Features
| Feature | Design Value |
|---|---|
| ±1 % VZ tolerance | Enables direct replacement of trimmed references in cost-sensitive consumer and industrial designs without calibration |
| 250 mW power rating | Supports continuous regulation in space-constrained applications such as wearable health monitors and IoT node power supervisors |
| 40 W surge capability | Provides robust protection against short-duration transients in automotive body electronics and industrial control I/O modules |
| SOT23 footprint compatibility | Allows drop-in integration into existing layouts using standard pick-and-place equipment and reflow profiles |
| 150 °C max junction temperature | Permits reliable operation in sealed enclosures or near heat-generating components without derating penalties |
Applications
| Microcontroller Reset Circuit | Sensor Signal Conditioning |
|---|---|
Use Scenario: Generating a clean, temperature-stable reset signal for an ARM Cortex-M0+ MCU operating from a 5 V rail. IC Role / Device Role / Timing Role: Shunt regulator providing precise 5.6 V reference to a reset supervisor IC (e.g., MAX809) that asserts reset until VCC exceeds threshold. Use Value: ±1 % VZ ensures reset assertion occurs within 10 mV of design target, eliminating false resets during brown-out conditions. | Use Scenario: Biasing the reference input of a 12-bit SAR ADC measuring thermistor voltage in a smart thermostat. IC Role / Device Role / Timing Role: Precision voltage reference source stabilizing ADC's internal reference divider network against supply ripple and temperature drift. Use Value: -2.0 to +2.5 mV/K temperature coefficient allows <±0.5 LSB error contribution over -25 °C to +70 °C operating range. |
| ESD Protection Clamp | Low-Power Voltage Monitor |
Use Scenario: Protecting RS-485 transceiver inputs from ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Fast-acting shunt clamp limiting transient voltage to 5.6 V + diode forward drop, diverting surge current away from sensitive input stages. Use Value: 40 W non-repetitive peak power rating absorbs 100 µs ESD pulses without degradation, validated per JEDEC JESD22-A114F. | Use Scenario: Monitoring lithium coin-cell voltage (2.0–3.3 V) in a medical patch sensor to trigger low-battery alert at 2.4 V. IC Role / Device Role / Timing Role: Low-leakage Zener used in comparator-based threshold detector, drawing <100 nA standby current when below trip point. Use Value: 1 µA max reverse current at 4.2 V ensures <50 nA loading on high-impedance divider, preserving battery life beyond 2 years. |

FAQ
What is the maximum continuous reverse current the BZX84-A5V6,215 can handle at 25 °C ambient?
The device is rated for 200 mA maximum forward current (IF), but as a Zener diode, its continuous reverse (Zener) current is limited by power dissipation. At 25 °C ambient on a standard FR4 PCB, Ptot = 250 mW implies IZ ≤ 44.6 mA (250 mW ÷ 5.6 V). Derating applies above 25 °C per Rth(j-a) = 500 K/W.
How does the "215" suffix in BZX84-A5V6,215 relate to packaging or marking?
The "215" is Nexperia's ordering code indicating tape-and-reel packaging in 3,000-unit reels (standard for SOT23), with moisture sensitivity level (MSL) 1 and RoHS-compliant finish. It does not affect electrical parameters - all BZX84-A5V6 variants share identical Zener characteristics and tolerance.
Can BZX84-A5V6,215 replace BZX84-C5V6 in an existing design?
Yes, but with trade-offs: the "A" grade offers ±1 % tolerance versus "C" grade's ±5 %, improving accuracy but increasing cost. The "C" version has higher max rdif (600 Ω vs. 400 Ω) and looser temperature coefficient (±5 mV/K vs. -2.0 to +2.5 mV/K), potentially affecting stability in temperature-varying environments.
Is thermal resistance to solder point (Rth(j-sp)) measured at pin 3 only?
Yes - Rth(j-sp) = 330 K/W is defined specifically at the cathode (pin 3) solder joint, as this terminal provides the dominant thermal conduction path from die to PCB. The anode (pin 1) and n.c. (pin 2) contribute negligibly to heat transfer and are excluded from this specification.
