Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. It features a silicon planar epitaxial construction, guaranteed Zener voltage at IZ = 5 mA, and specified leakage current ≤ 100 nA at 1 V reverse bias.
The device complies with AEC-Q200 Grade 1 for automotive use and supports soldering per JEDEC J-STD-020, with thermal resistance Rthj-a = 400 K/W in SOT23 package - enabling reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V ±5% at IZ = 5 mA - defines precise clamping threshold for low-voltage rail stabilization |
| Power Dissipation (Ptot) | 500 mW - limits maximum continuous power handling in SOT23 footprint without derating |
| Dynamic Impedance (ZZ) | 90 Ω max at IZ = 5 mA - determines voltage regulation sensitivity to current variation |
| Reverse Leakage (IR) | ≤100 nA at VR = 1 V - ensures minimal quiescent current in standby bias networks |
| Junction Temperature (Tj) | −65 °C to +150 °C - enables deployment in extended-temperature industrial and automotive environments |
| Package | SOT23 - 3-pin surface-mount outline compatible with standard pick-and-place and reflow processes |
Pinout & Package
SOT23 package: plastic surface-mount case with three leads; cathode marked by band on top surface; pin 1 = anode, pin 2 = cathode, pin 3 = not connected (NC) - confirmed per Nexperia SOT23 mechanical drawing SOT23.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | 2.4 V nominal VZ, ±5%, 350 mW Ptot, SOT23 package | Lower clamping voltage; reduced power margin for sustained transients | Select when 2.4 V reference is required and peak power stress remains below 350 mW |
| BZX84-C3V0,215 | 3.0 V nominal VZ, ±5%, 300 mW Ptot, same SOT23 footprint | Higher regulation voltage; lower power rating limits surge energy absorption | Choose for 3.0 V biasing where tighter thermal management is feasible |
Compared with BZX84-C2V7/DG/B2,2, MMBZ5221BS-7-F offers lower voltage but less surge capacity, while BZX84-C3V0,215 provides higher VZ at reduced power - making the original optimal for 2.7 V, 500 mW-critical designs.

FAQ
What is the maximum reverse current before breakdown for BZX84-C2V7/DG/B2,2?
The device exhibits ≤100 nA reverse leakage at 1 V applied reverse bias, per Nexperia's datasheet. Breakdown begins near 2.4 V (lower limit of 2.7 V ±5%), with full regulation established at 5 mA test current - no defined "maximum pre-breakdown current" is specified beyond the leakage limit.
Can BZX84-C2V7/DG/B2,2 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficient and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. For higher power, select a single higher-rated Zener (e.g., 1 W SOD-123 device) or implement active regulation.
Is the SOT23 package lead-free and RoHS compliant?
Yes - BZX84-C2V7/DG/B2,2 meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound, verified per Nexperia's material declarations and JEDEC J-STD-020 moisture sensitivity level 1 rating.
How does temperature affect the Zener voltage stability?
VZ drifts at +2.5 mV/°C typical over −65 °C to +150 °C, due to the device's low-voltage Zener mechanism. This results in ~±15 mV shift across a 125 °C operating range - acceptable for non-precision biasing but insufficient for metrology-grade references.
