Product details
Overview
PDZ2.7B,115 from Nexperia is a single Zener diode designed for low-power voltage regulation in space-constrained SMD applications, with a nominal Zener voltage of 2.7 V at 5 mA, ±2 % tolerance, 400 mW total power dissipation, and 20 Ω maximum differential resistance at IZ = 5 mA - deployed in precision reference and overvoltage clamp circuits on industrial sensor signal conditioning boards.
For engineers reviewing the PDZ2.7B,115 datasheet, PDZ2.7B,115 pinout, PDZ2.7B,115 application, or PDZ2.7B,115 equivalent, this device is selected for stable low-voltage reference generation where tight VZ tolerance, low leakage (<20 µA at VR = 2.0 V), and hard breakdown knee are required in 2.7 V rail protection schemes.
Technical Context
The PDZ2.7B,115 operates as a two-terminal voltage reference diode with reverse-biased Zener breakdown behavior. Its 2.7 V nominal working voltage is specified at IZ = 5 mA, with typical temperature coefficient of −2.0 mV/K and maximum dynamic impedance of 20 Ω under same conditions.
It exhibits hard breakdown characteristics and low leakage current (≤20 µA at VR = 2.0 V), enabling reliable clamping in low-current bias networks. Thermal resistance from junction to ambient is 340 K/W on standard FR4 PCB, limiting continuous power handling above +25 °C per the derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.69 V to 2.91 V at IZ = 5 mA - ensures ±2 % regulation accuracy for 2.7 V reference rails |
| Differential Resistance rdif | ≤20 Ω at IZ = 5 mA - maintains stable output under small load variations |
| Reverse Leakage IR | ≤20 µA at VR = 2.0 V - minimizes quiescent current in battery-powered bias networks |
| Total Power Dissipation Ptot | 400 mW at Tamb ≤ 25 °C - supports operation in compact SOD323 footprint without forced cooling |
| Forward Voltage VF | 0.9 V at IF = 10 mA - defines forward conduction threshold for bidirectional protection use cases |
| Thermal Resistance Rth(j-a) | 340 K/W on FR4 PCB - determines safe operating area under ambient temperature rise |
| Package | SOD323 (SC-76) - 1.35 mm × 0.85 mm footprint compatible with high-density reflow assembly |
Pinout & Package
PDZ2.7B,115 uses a 2-pin SOD323 surface-mount plastic package. The cathode is marked by a bar on the component body; anode and cathode terminals are arranged linearly with 0.95 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated voltage node; reverse-biased during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes Zener conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage Zener reference | 2.7 V nominal with ±2 % tolerance enables accurate 2.7 V rail stabilization in analog front-ends |
| Hard breakdown knee | Sharp transition from non-conduction to regulation improves noise immunity in sensing circuits |
| Low leakage current | ≤20 µA at 2.0 V reverse bias preserves battery life in always-on monitoring nodes |
| Small SMD package | SOD323 footprint (1.35 × 0.85 mm) allows placement near IC power pins for local decoupling |
| High surge capability | 8.0 A non-repetitive peak reverse current supports transient overvoltage suppression |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V7 | Same 2.7 V nominal, ±2 % tolerance, but SOD323 package with 300 mW Ptot rating | Limited to lower-power clamping due to 100 mW lower dissipation margin | Select when thermal budget is constrained and peak power < 300 mW suffices |
| MMSZ4678T1G | 2.7 V nominal, ±5 % tolerance, 500 mW Ptot, SOD123 package (larger footprint) | Looser tolerance increases reference uncertainty; higher Ptot supports higher surge duty cycles | Select when board layout permits larger SOD123 and ±5 % VZ is acceptable |
Compared with BZX384-B2V7 and MMSZ4678T1G, PDZ2.7B,115 delivers tighter tolerance and higher surge rating in the smallest SOD323 footprint, making it optimal for high-density, precision-clamp designs where thermal margin and space are jointly constrained.

FAQ
What is the maximum reverse current before breakdown for PDZ2.7B,115?
The PDZ2.7B,115 exhibits ≤20 µA reverse leakage current at VR = 2.0 V and Tj = 25 °C. Breakdown begins near 2.69 V (VZ min) at IZ = 5 mA, with no defined "pre-breakdown" threshold - it transitions sharply from leakage to regulation due to its hard knee characteristic.
Can PDZ2.7B,115 be used in forward-bias mode as a regular diode?
Yes - its forward voltage is 0.9 V at 10 mA and 1.1 V at 100 mA, matching typical silicon diode behavior. However, it is not optimized for rectification; its primary design intent and characterization are for reverse-biased Zener operation, and forward surge ratings are not specified beyond absolute maximum IF = 200 mA continuous.
How does temperature affect the Zener voltage of PDZ2.7B,115?
PDZ2.7B,115 has a negative temperature coefficient of −2.0 mV/K at IZ = 5 mA. This means VZ decreases by approximately 2 mV per Kelvin rise in junction temperature, resulting in ~−10 mV shift over a 50 °C rise - critical for precision references requiring thermal compensation.
Is PDZ2.7B,115 suitable for automotive applications?
No - PDZ2.7B,115 is not automotive-qualified. It is rated for industrial temperature range (−65 °C to +150 °C storage, max Tj = +150 °C), but lacks AEC-Q200 qualification, automotive-grade screening, or guaranteed PPAP documentation. Use only in non-safety-critical commercial or industrial systems.
