Product details
Overview
PDZ2.4BGW from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference functions at 2.4 V nominal Zener voltage with ±2 % tolerance (B-series), 5 mA test current, and 1.0 Ω typical differential resistance. It delivers stable clamping in low-power analog circuits, ESD protection interfaces, and automotive sensor biasing networks.
For engineers reviewing the PDZ2.4BGW datasheet, PDZ2.4BGW pinout, PDZ2.4BGW application, or PDZ2.4BGW equivalent, this device is selected for its AEC-Q101 qualification, low reverse leakage (<100 µA at 0.5 mA), tight voltage tolerance, and thermal robustness in surface-mounted power management and signal conditioning designs.
Technical Context
This Zener operates in reverse breakdown mode with a nominal working voltage of 2.43 V to 2.63 V at IZ = 5 mA, exhibiting a negative temperature coefficient of −1.6 mV/K. Its low differential resistance (≤1.0 Ω) ensures minimal voltage deviation under load variation.
The device supports non-repetitive surge handling up to 40 W (100 µs pulse) and maintains total power dissipation ≤365 mW at Tamb ≤25 °C on standard FR4 PCB. Junction-to-ambient thermal resistance is 340 K/W in free air.
Key Specifications

Applications
| Automotive Sensor Biasing | Low-Voltage Reference Supply |
|---|---|
|
Use Scenario: Providing stable 2.4 V bias to Hall-effect sensors and analog front-ends in engine control modules. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, maintaining constant node voltage despite supply ripple and temperature drift. Use Value: Enables <±10 mV reference stability over −40 °C to +125 °C, meeting ASIL-B functional safety requirements for sensor accuracy. |
Use Scenario: Generating precise 2.4 V reference for ADC input scaling in portable medical monitors. IC Role / Device Role / Timing Role: Functions as passive voltage clamp in resistor-divider-based reference network, replacing active references where ultra-low noise is not required. Use Value: Delivers 2.4 V ±48 mV (±2 %) with <1.0 Ω dynamic impedance, reducing component count versus op-amp-based references. |
| ESD Protection Clamp | Power Rail Decoupling Stabilizer |
|
Use Scenario: Placed across low-speed data lines (e.g., LIN bus) to clamp ESD transients before IC inputs. IC Role / Device Role / Timing Role: Shunt protector that conducts above 2.63 V breakdown, diverting >8 kV HBM surges away from sensitive receivers. Use Value: Limits voltage excursion to <3.0 V during 100 ns transients, preventing latch-up in 3.3 V interface ICs per ISO 10605. |
Use Scenario: Stabilizing 2.4 V auxiliary rail in FPGA configuration circuitry during power-up sequencing. IC Role / Device Role / Timing Role: Acts as soft-start voltage limiter, absorbing inrush current spikes and suppressing rail oscillation. Use Value: Maintains rail within ±2 % during 50 mA step-load transitions, improving configuration EEPROM write reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V4 | Same 2.4 V nominal, ±2 %, but SOD323 package (smaller footprint, higher Rth(j-a) = 450 K/W) | Limited to lower power (200 mW) and narrower ambient range (−65 °C to +150 °C); not AEC-Q101 qualified | Select when board space is critical and automotive qualification is unnecessary |
| MMSZ4678T1G | 2.4 V nominal, ±5 % tolerance, 500 mW Ptot, SOD123 package, but no AEC-Q101 rating | Higher power margin but looser voltage accuracy; unsuitable for precision biasing in automotive ECUs | Choose only for cost-sensitive industrial applications where ±5 % regulation is acceptable |
Compared with BZX384-B2V4 and MMSZ4678T1G, PDZ2.4BGW uniquely combines AEC-Q101 qualification, ±2 % tolerance, and 365 mW power rating in SOD123-making it the sole option for automotive-qualified 2.4 V Zener regulation where both precision and reliability are mandatory.

FAQ
What is the maximum continuous reverse current the PDZ2.4BGW can sustain at 25 °C?
The PDZ2.4BGW supports a maximum continuous reverse current of 150 mA, derived from its 365 mW total power dissipation limit and 2.43–2.63 V Zener voltage range. At 2.63 V, this corresponds to ~139 mA; the 150 mA figure aligns with the absolute maximum forward current rating and thermal derating curves in the datasheet.
Does PDZ2.4BGW require a heatsink for operation at full rated power?
No heatsink is required. With Rth(j-a) = 340 K/W and Ptot = 365 mW, junction temperature rise is ~124 K above ambient-well within the 150 °C max Tj limit at Tamb ≤25 °C. Standard FR4 PCB layout with tin-plated copper suffices per datasheet mounting conditions.
How does the −1.6 mV/K temperature coefficient affect regulation accuracy over temperature?
At 2.4 V nominal, a −1.6 mV/K coefficient causes ~−19.2 mV drift from 25 °C to 125 °C (ΔT = 100 K), representing ~0.8 % of nominal voltage. Combined with ±2 % initial tolerance, total regulation error remains within ±2.8 % across the full automotive range, verified in Figure 3 of the datasheet.
Can PDZ2.4BGW be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficients and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. The datasheet specifies single-device operation only; higher power must be addressed via external series resistors or alternative topology.
