Product details
Overview
BZX884-B24,315 from Nexperia is a ±2% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 24 V nominal Zener voltage at 5 mA, 250 mW total power dissipation, and 60 Ω typical differential resistance at IZ = 5 mA - used for precision voltage regulation and ESD protection in space-constrained DC power rails.
For engineers reviewing the BZX884-B24,315 datasheet, BZX884-B24,315 pinout, BZX884-B24,315 application, or BZX884-B24,315 equivalent, this page delivers verified Zener voltage tolerance, thermal resistance, reverse leakage at 16.8 V, junction temperature limit, and AEC-Q101 qualification status - critical for automotive and industrial power rail stabilization design.
Technical Context
This Zener diode operates in reverse breakdown with a nominal 24 V regulation point at 5 mA test current, exhibiting a +20.4 mV/K temperature coefficient and 55 pF capacitance at 1 MHz/0 V bias. Its ultra-small DFN1006-2 footprint enables high-density PCB layouts while maintaining stable regulation under transient load conditions.
The device supports non-repetitive peak reverse current up to 1.25 A (100 µs pulse), withstands ambient temperatures from −55 °C to +150 °C, and achieves 500 K/W junction-to-ambient thermal resistance on standard FR4 PCB - enabling reliable operation in thermally demanding environments without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 23.52 V to 24.48 V at IZ = 5 mA - ensures tight 2% regulation window for stable reference in feedback loops. |
| Differential Resistance (rdiff) | 60 Ω max at IZ = 5 mA - limits output voltage deviation under varying load currents. |
| Reverse Leakage (IR) | 100 nA max at VR = 16.8 V - minimizes standby power loss in low-current bias networks. |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling on standard PCB layout. |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive and industrial control environments. |
| AEC-Q101 Qualified | Validated for automotive-grade reliability - required for use in safety-critical vehicle subsystems. |
| Package | SOD882 (DFN1006-2), 1.0 × 0.6 × 0.5 mm - enables 0201-class board area usage with solderable side terminals. |
Pinout & Package
SOD882 (DFN1006-2) is a leadless, surface-mount plastic package with two terminals and a transparent top view; the cathode is marked by a bar on the package body.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5249BS-7-F | ±5% tolerance, 24 V nominal, SOT-323 package (2.1 × 1.3 mm), 350 mW Ptot | Larger footprint, higher power, looser tolerance - suitable where board space is less constrained and tighter regulation not required. | Select when needing higher surge margin and accepting ±5% VZ variation in cost-sensitive industrial designs. |
| BZX84-C24,215 | ±5% tolerance, same SOD882 package, identical 250 mW rating, 24 V nominal | Same form factor but wider voltage spread (22.8–25.2 V); higher reverse leakage (200 nA at 16.8 V) | Choose for non-automotive applications where AEC-Q101 is unnecessary and ±5% regulation suffices. |
Compared with BZX884-B24,315, MMBZ5249BS-7-F offers higher power but sacrifices precision and miniaturization, while BZX84-C24,215 matches size and power but trades AEC-Q101 compliance and tighter tolerance for lower cost - making the BZX884-B24,315 optimal for space-limited, automotive-grade 24 V regulation.

FAQ
What is the maximum reverse voltage the BZX884-B24,315 can safely clamp?
The BZX884-B24,315 is rated for non-repetitive peak reverse voltage up to 1.25 A at 100 µs pulse width (per Table 8), corresponding to a peak clamping voltage of approximately 27.5 V under surge conditions. Continuous reverse operation must remain within its 24 V ±2% Zener range to avoid thermal runaway.
Does the SOD882 package require special reflow profile considerations?
Yes - the SOD882 package requires strict adherence to Nexperia's recommended reflow profile (documented in Figure 12), with peak temperature limited to 260 °C for ≤10 seconds and ramp rates controlled to prevent solder voiding or die attach delamination. Standard lead-free reflow is supported, but wave soldering is not recommended.
How does the +20.4 mV/K temperature coefficient affect regulation stability?
The +20.4 mV/K coefficient means VZ increases by ~20.4 mV per 1 °C rise in junction temperature. At full 150 °C Tj, this adds ~2.5 V to the nominal 24 V rating - a known, linear drift that must be compensated in high-accuracy references via circuit design or calibration, not a failure mode.
Is the BZX884-B24,315 suitable for bidirectional ESD protection?
No - it is a unidirectional Zener diode configured for reverse-bias regulation only. For bidirectional ESD suppression (e.g., USB data lines), a dedicated TVS array like PESD5V0S1BA should be used; this part functions solely as a cathode-grounded voltage clamp in DC power rails.
