Product details
Overview
PZU24B2L,315 from NXP Semiconductors is a precision ±2 % tolerance Zener diode in SOD882 ultra-small surface-mount package, rated for 24 V nominal Zener voltage at 5 mA, 250 mW total power dissipation, and 40 W non-repetitive peak reverse power handling - used for voltage regulation and reference in space-constrained automotive and industrial PCBs.
For engineers reviewing the PZU24B2L,315 datasheet, PZU24B2L,315 pinout, PZU24B2L,315 application, or PZU24B2L,315 equivalent, key selection criteria include its AEC-Q101 qualification, low differential resistance (120 Ω), tight 2 % voltage tolerance, thermal resistance of 250 K/W on standard FR4, and reflow-only soldering compatibility.
Technical Context
This device operates as a single-terminal voltage reference with cathode-anode polarity, designed for stable DC voltage clamping and regulation under steady-state and transient surge conditions. Its Zener breakdown mechanism delivers predictable reverse conduction at 24 V with temperature coefficient of +1.3 mV/K and reverse current ≤30 nA at 19.2 V.
The SOD882 package enables high-density placement with minimal board area (1.0 × 0.6 mm footprint), while thermal performance is optimized for FR4 PCBs with single-sided copper and standard solder pads - supporting reliable operation up to 150 °C junction temperature.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 24 V nominal at IZ = 5 mA; ±2 % tolerance ensures precise regulation in feedback loops and reference circuits |
| Differential Resistance (rdif) | 120 Ω max at IZ = 5 mA; low impedance maintains stable output under load variation |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤25 °C; defines continuous DC power handling on standard FR4 layout |

| Reverse Current (IR) | ≤30 nA at VR = 19.2 V; enables low-leakage biasing and high-impedance sensing |
| Temperature Coefficient (SZ) | +1.3 mV/K at IZ = 5 mA; positive drift improves stability across automotive temperature range |
| Junction Temperature (Tj) | 150 °C maximum; allows operation in under-hood and industrial control environments |
Pinout & Package
SOD882 is a leadless ultra-small plastic surface-mount package measuring 1.0 × 0.6 × 0.5 mm, with cathode marked by a bar on the top surface. The device mounts directly onto FR4 PCBs using reflow soldering only, with recommended footprint per Figure 9 (NXP doc mbl872).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C24,215 | ±5 % tolerance (vs. ±2 %), SOT23 package (1.3 × 1.75 mm), 300 mW Ptot, higher rdif (150 Ω) | Less precise regulation; larger footprint limits high-density layouts; suitable for non-critical biasing | Select when cost sensitivity outweighs tolerance and size requirements |
| MMSZ4687T1G | ±5 % tolerance, SOD123 package (2.7 × 1.6 mm), 500 mW Ptot, 100 nA IR at 19.2 V | Higher power handling but larger size; higher leakage reduces suitability for ultra-low-power sensor nodes | Prefer where higher continuous power is needed and board space permits larger package |
Compared with BZX84-C24,215 and MMSZ4687T1G, PZU24B2L,315 offers superior voltage accuracy and smallest footprint - critical for automotive and portable medical designs where regulation precision and PCB area are constrained.

FAQ
What is the Zener voltage tolerance of PZU24B2L,315 and how does it impact circuit accuracy?
The PZU24B2L,315 has a ±2 % Zener voltage tolerance at 5 mA, meaning its actual breakdown voltage falls between 23.52 V and 24.48 V. This tight tolerance directly improves accuracy in voltage reference and feedback applications - for example, reducing ADC measurement error by up to 40 % compared to ±5 % Zeners in 24 V-scaled systems. The PZU24B2L,315 achieves this via laser-trimmed wafer-level process control.
Is PZU24B2L,315 suitable for automotive applications and what qualification does it hold?
Yes, PZU24B2L,315 is AEC-Q101 qualified for discrete semiconductors, having passed stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock. It is approved for use in automotive body control modules, lighting drivers, and infotainment power supplies. The PZU24B2L,315 meets all requirements for Grade 1 (−40 °C to +125 °C ambient) operation per AEC-Q101 Rev D.
What is the maximum non-repetitive peak reverse current (IZSM) for PZU24B2L,315 and under what conditions is it specified?
The PZU24B2L,315 supports a non-repetitive peak reverse current of 19 A at 100 µs pulse width, square wave, with junction temperature at 25 °C prior to surge. This value is derived from its 40 W PZSM rating and 24 V nominal Zener voltage (IZSM = PZSM/VZ). The PZU24B2L,315 uses this capability for transient suppression in 24 V supply lines subject to ISO 7637-2 pulses.
Can PZU24B2L,315 be hand-soldered or is reflow required?
Reflow soldering is the only recommended method for PZU24B2L,315 per NXP documentation - hand soldering is not advised due to thermal stress risks on the ultra-small SOD882 package. The PZU24B2L,315 requires strict adherence to J-STD-020 moisture sensitivity level (MSL) 1 profile, with peak reflow temperature of 260 °C for ≤30 seconds. Deviation may cause delamination or parametric shift.
How does the thermal resistance of PZU24B2L,315 compare between free air and PCB-mounted conditions?
The PZU24B2L,315 exhibits Rth(j-a) = 500 K/W in free air but drops to 250 K/W when mounted on an FR4 PCB with standard single-sided copper footprint - doubling its effective power handling. This 2× improvement is enabled by copper pad conduction; the PZU24B2L,315 datasheet specifies 1 cm² cathode pad area for the 250 K/W value, making thermal design highly layout-dependent.
