Product details
Overview
PDZ2.7BGW from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications at 2.7 V nominal Zener voltage with ±2 % tolerance (B-series), 20 μA max reverse current at 1 V, 1.0 Ω typical differential resistance at 5 mA, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the PDZ2.7BGW datasheet, PDZ2.7BGW pinout, PDZ2.7BGW application, or PDZ2.7BGW equivalent, this device is selected for low-voltage rail clamping, ESD-protected biasing, and stable reference generation where tight voltage tolerance, low thermal drift, and surface-mount reliability are critical.
Technical Context
This Zener operates in reverse breakdown mode with a nominal working voltage of 2.7 V at IZ = 5 mA, exhibiting a negative temperature coefficient of −2.0 mV/K - enabling predictable thermal behavior in ambient ranges from −55 °C to +150 °C. Its low 1.0 Ω dynamic impedance ensures minimal voltage deviation under load transients.
The device supports non-repetitive surge handling up to 40 W (100 μs pulse) and continuous power dissipation of 365 mW on standard FR4 PCB, with junction-to-ambient thermal resistance of 340 K/W in free air - confirming suitability for compact, thermally constrained layouts without heatsinking.
Key Specifications

|---|---|
| Zener Voltage VZ | 2.69 V to 2.91 V at IZ = 5 mA - defines precise clamping threshold for 2.7 V rails |
| Tolerance | ±2 % (B-series) - enables accurate voltage referencing without post-calibration |
| Differential Resistance rdif | ≤1.0 Ω at IZ = 5 mA - ensures <10 mV output shift per 10 mA load change |
| Reverse Current IR | ≤20 μA at VR = 1 V - guarantees low leakage in standby-biased circuits |
| Power Dissipation Ptot | 365 mW at Tamb ≤ 25 °C - supports continuous operation on standard SMD footprints |
| Temperature Coefficient SZ | −2.0 mV/K at IZ = 5 mA - allows predictable compensation in temperature-sensitive references |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V7 | Same 2.7 V nominal, ±2 %, but SOD323 package (smaller, higher thermal resistance: 450 K/W) | Limited to lower-power (<200 mW) or space-constrained designs; not AEC-Q101 qualified | Select when board area is critical and automotive qualification is unnecessary |
| MMSZ4678T1G | 2.7 V nominal, ±5 % tolerance, SOD123 package, 500 mW Ptot, no AEC-Q101 | Higher tolerance increases reference uncertainty; higher power rating suits higher-current clamping | Select when cost sensitivity outweighs precision and automotive compliance requirements |
Compared with BZX384-B2V7 and MMSZ4678T1G, PDZ2.7BGW uniquely combines AEC-Q101 qualification, ±2 % tolerance, and SOD123 thermal performance - making it the only choice for automotive-qualified, precision low-voltage regulation where reliability and accuracy are jointly mandated.

FAQ
What is the maximum reverse voltage (VR) that PDZ2.7BGW can block before breakdown?
PDZ2.7BGW begins controlled Zener conduction at its specified nominal voltage range of 2.69 V to 2.91 V when tested at IZ = 5 mA. Below 1.0 V reverse bias, its leakage remains ≤20 μA - meaning it reliably blocks up to 1.0 V without significant conduction. Operation above 2.91 V enters the designed breakdown region, not blocking but regulating.
Can PDZ2.7BGW be used in parallel for higher power dissipation?
No - Zener diodes exhibit manufacturing variations in VZ and dynamic impedance, causing current imbalance when paralleled. Even two PDZ2.7BGW units will not share current equally due to ±2 % tolerance and differing rdif; one device will dominate conduction and likely overheat. Use a single higher-rated Zener or external current-sharing resistors if increased power handling is required.
Is the SOD123 package lead-free and RoHS compliant?
Yes - PDZ2.7BGW is manufactured using lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The SOD123 package uses matte tin plating over nickel barrier, qualified for standard lead-free reflow profiles (JEDEC J-STD-020).
How does the −2.0 mV/K temperature coefficient affect circuit design?
The negative temperature coefficient means VZ decreases by approximately 2.0 mV per Kelvin rise in junction temperature. At 125 °C ambient (with self-heating), VZ may drop ~200 mV from its 25 °C value - requiring derating in high-temp applications or pairing with positive-TC components (e.g., forward-biased diodes) for compensation in precision references.
