Product details
Overview
PDZ12BGW115 from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications with nominal Zener voltage of 12 V at 5 mA, ±2 % tolerance (B-series), 80 Ω maximum differential resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDZ12BGW115 datasheet, PDZ12BGW115 pinout, PDZ12BGW115 application, or PDZ12BGW115 equivalent, this device supports stable low-power voltage clamping, overvoltage protection in sensor interfaces, and biasing in automotive control modules where tight voltage tolerance and thermal reliability are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 11.74 V to 12.24 V at IZ = 5 mA, exhibiting a temperature coefficient of +8.4 mV/K - indicating positive drift with junction temperature rise. Its low reverse current (≤0.1 μA at VR = 9.0 V) ensures minimal leakage in standby circuits.
The device delivers non-repetitive peak reverse power dissipation up to 40 W (tp = 100 μs), supported by a thermal resistance from junction to solder point of 50 K/W when mounted on an FR4 PCB with 1 cm² cathode pad, enabling robust transient suppression in compact layouts.

Applications
| Automotive Sensor Biasing | Microcontroller Voltage Reference |
|---|---|
Use Scenario: Providing stable 12 V reference for analog front-ends in wheel speed or pressure sensors within engine compartments. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, maintaining constant bias voltage despite supply ripple and temperature variation. Use Value: ±2 % tolerance and +8.4 mV/K TC ensure <±30 mV total drift across −40 °C to +125 °C, meeting ASIL-B sensor accuracy requirements. |
Use Scenario: Generating precise 12 V reference for ADC input scaling in automotive body control modules (BCMs). IC Role / Device Role / Timing Role: Functions as passive voltage clamp and reference source for internal ADC reference divider networks. Use Value: Low 0.1 μA reverse leakage prevents loading of high-impedance reference dividers, preserving measurement linearity. |
| Overvoltage Protection Clamp | Power Supply Rail Stabilization |
Use Scenario: Clamping transients on 12 V power rails feeding infotainment head units during load-dump events. IC Role / Device Role / Timing Role: Shunt element that conducts excess energy above 12.24 V to ground during short-duration surges. Use Value: 40 W non-repetitive peak power rating handles ISO 7637-2 Pulse 5a waveforms without failure when paired with series impedance. |

IC Role / Device Role / Timing Role: Maintains regulated voltage for low-noise LDO input stages during dynamic load changes. Use Value: 80 Ω differential resistance limits output voltage deviation to <0.8 V under 10 mA load step, improving downstream regulator PSRR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C12 | ±5 % tolerance, SOT23 package, 350 mW Ptot, no AEC-Q101 qualification | Lower cost for non-automotive consumer applications; lacks automotive reliability validation | Select when AEC-Q101 is not required and board space permits larger SOT23 footprint |
| MMSZ4687T1G | ±5 % tolerance, SOD123 package, 500 mW Ptot, no AEC-Q101 qualification | Higher power rating but wider voltage tolerance; suitable for industrial power supplies | Choose for higher continuous dissipation needs where ±2 % is not critical and automotive qualification is unnecessary |
Compared with BZX84-C12 and MMSZ4687T1G, PDZ12BGW115 uniquely combines AEC-Q101 qualification, ±2 % tolerance, and SOD123 form factor - making it the only option qualified for safety-critical automotive voltage reference functions without derating or additional validation.

FAQ
What is the maximum continuous reverse current the PDZ12BGW115 can sustain at 12 V?
The PDZ12BGW115 is rated for a maximum reverse current of 0.1 μA at VR = 9.0 V (Table 8). At exactly 12 V, it operates in full Zener breakdown; sustained current is limited by thermal design - with Ptot = 365 mW, the absolute maximum continuous Zener current is ~30 mA at 12 V, assuming adequate PCB heat sinking per the 50 K/W Rth(j-sp) specification.
Is the PDZ12BGW115 suitable for bidirectional transient voltage suppression?
No - PDZ12BGW115 is a unidirectional Zener diode configured for reverse-bias operation only. It does not provide forward conduction protection like a TVS diode. For bidirectional surge suppression, a dedicated bidirectional TVS (e.g., PESD5V0S1BA) must be used; this part serves strictly as a shunt voltage reference or unidirectional clamp.
How does the +8.4 mV/K temperature coefficient affect regulation accuracy over temperature?
At IZ = 5 mA, the +8.4 mV/K coefficient means VZ increases by ~0.84 V over a 100 K rise (e.g., −40 °C to +60 °C ambient). Combined with initial ±2 % tolerance (±240 mV), total VZ variation is ±1.08 V across that range - acceptable for non-precision biasing but requires compensation in high-accuracy references.
Can PDZ12BGW115 replace PDZ12B in legacy designs?
Yes - PDZ12BGW115 is the updated SOD123 variant of the legacy PDZ12B (SOD323), sharing identical electrical specs (VZ, tolerance, rdif) and AEC-Q101 qualification. The SOD123 package offers higher power handling (365 mW vs. 300 mW) and improved thermal performance, making it a direct drop-in upgrade with enhanced robustness.
