Product details
Overview
PZU7.5B2L from NXP Semiconductors is a precision Zener diode optimized for voltage regulation and reference applications, featuring a nominal Zener voltage of 7.5 V with ±2 % tolerance, differential resistance of 60 Ω at 5 mA, and low reverse current of 10 nA at 5 V, used in automotive power supply monitoring and sensor biasing circuits.
For engineers reviewing the PZU7.5B2L datasheet, PZU7.5B2L pinout, PZU7.5B2L application, or PZU7.5B2L equivalent, key selection criteria include tight voltage tolerance, AEC-Q101 qualification, SOD882 ultra-small footprint compatibility, and thermal performance under transient surge conditions.
Technical Context
The PZU7.5B2L operates as a single-terminal voltage reference device with cathode-anode polarity defined by a top-side marking bar. Its Zener breakdown mechanism delivers stable regulation at 7.5 V with temperature coefficient of +4.0 mV/K at 5 mA, enabling predictable drift compensation in analog front-ends.
Designed for reflow-only assembly on FR4 PCBs, it supports non-repetitive peak reverse power dissipation up to 40 W (100 µs square wave) and total power dissipation of 250 mW at ambient ≤25 °C, with junction-to-ambient thermal resistance of 500 K/W in free air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.28 V to 7.60 V at IZ = 5 mA - ensures ±2 % regulation accuracy across production lots |
| Differential Resistance (rdif) | 60 Ω max at IZ = 5 mA - maintains low output impedance for stable reference under load variation |
| Reverse Current (IR) | 10 nA max at VR = 5 V - enables ultra-low leakage in battery-powered sensor nodes |
| Temperature Coefficient (SZ) | +4.0 mV/K typical at IZ = 5 mA - allows predictable voltage drift compensation in automotive ambient ranges |
| Non-repetitive Peak Reverse Current (IZSM) | 3.5 A at tp = 100 µs - supports transient overvoltage clamping without failure |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - defines continuous DC power handling on standard FR4 layout |
| Junction Temperature (Tj) | 150 °C max - enables operation in under-hood automotive environments |

FAQ
What is the Zener voltage tolerance of PZU7.5B2L?
The PZU7.5B2L has a nominal Zener voltage of 7.5 V with a tolerance of ±2 %, corresponding to a guaranteed range of 7.28 V to 7.60 V at 5 mA test current. This B2-series tolerance is tighter than the ±5 % option (PZU7.5BL), making PZU7.5B2L suitable for applications demanding higher reference accuracy without post-production calibration.
Is PZU7.5B2L qualified for automotive use?
Yes, the PZU7.5B2L is AEC-Q101 qualified per the Automotive Electronics Council standard for discrete semiconductors. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life-confirming its suitability for under-hood and cabin-mounted automotive electronics where reliability under thermal and vibration stress is critical.
What package type does PZU7.5B2L use and how is polarity marked?
The PZU7.5B2L uses the SOD882 leadless ultra-small plastic package measuring 1.0 × 0.6 × 0.5 mm. Polarity is indicated by a marking bar on the top surface, which identifies Pin 1 as the cathode. The anode is Pin 2, located opposite the bar-this orientation must be observed during PCB layout and placement to ensure correct shunt regulation behavior.
What is the maximum non-repetitive peak reverse current for PZU7.5B2L?
The PZU7.5B2L supports a non-repetitive peak reverse current (IZSM) of 3.5 A under 100 µs square-wave pulse conditions at Tj = 25 °C prior to surge. This value is derived from its 40 W non-repetitive peak reverse power dissipation rating and enables effective transient suppression in 12 V automotive systems experiencing load dump or ESD events.
Can PZU7.5B2L be hand-soldered or is reflow required?
Reflow soldering is the only recommended soldering method for PZU7.5B2L, as specified in the official NXP datasheet. Hand soldering-including hot-air or iron-based techniques-is not qualified and may compromise thermal integrity, intermetallic formation, or mechanical reliability due to the SOD882 package's leadless construction and small pad geometry.
