Product details
Overview
BZX84J-B5V1,115 from Nexperia is a ±2 % tolerance Zener diode in SOD323F (SC-90) package, rated for 5.1 V nominal regulation at 5 mA test current, with 480 Ω typical differential resistance and 2 µA max reverse leakage at 3.8 V. It delivers stable voltage reference in low-power analog circuits and ESD-protected I/O clamping networks.
For engineers reviewing the BZX84J-B5V1,115 datasheet, BZX84J-B5V1,115 pinout, BZX84J-B5V1,115 application, or BZX84J-B5V1,115 equivalent, this device serves as a precision, AEC-Q101-qualified voltage regulator for automotive sensor interfaces, power rail monitoring, and microcontroller reset circuitry where tight tolerance and thermal stability are required.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 5.1 V reference across load variations, with temperature coefficient of −2.7 mV/K to +1.2 mV/K over 25–150 °C. Its low 480 Ω differential resistance ensures minimal output voltage drift under dynamic current changes.
Designed for surface-mount reliability, it supports non-repetitive surge handling up to 40 W (100 µs square wave, Tj = 25 °C), and sustains continuous 550 mW total dissipation on FR4 PCB with 1 cm² cathode pad - enabling robust operation in transient-prone automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 5.1 V at IZ = 5 mA - defines precise regulation point for reference and clamping functions |
| Tolerance | ±2 % - enables tighter system-level voltage margin control vs. ±5 % variants |
| Differential Resistance | 480 Ω max at IZ = 5 mA - determines regulation stiffness and load-induced voltage deviation |
| Reverse Leakage Current | 2 µA max at VR = 3.8 V - ensures low standby power loss in always-on monitoring circuits |
| Total Power Dissipation | 550 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 layout |
| Non-repetitive Peak Power | 40 W (100 µs, square wave) - defines surge immunity capability for ESD and load-dump transients |
| Junction Temperature Range | −55 °C to +150 °C - supports operation in under-hood automotive and industrial ambient conditions |
Pinout & Package
SOD323F (SC-90) plastic surface-mount package: ultra-compact 2.3 mm × 1.35 mm footprint with 0.65 mm height and gull-wing leads; optimized for high-density PCB assembly and automated reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - reverse-biased during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes bias path for controlled breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114 |
| Low differential resistance | 480 Ω max ensures <10 mV output shift per 20 mA load change - critical for precision references |
| Wide operating temperature range | −55 °C to +150 °C junction operation supports engine control units and ADAS modules |
| Small SOD323F package | 0.65 mm profile and 2.3 mm × 1.35 mm footprint enable placement near IC pins for local decoupling/clamping |
| Controlled temperature coefficient | −2.7 to +1.2 mV/K allows predictable drift compensation in temperature-sensitive analog designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1,115 | ±5 % tolerance, 600 Ω rdiff, same SOD323F package and 5.1 V nominal | Lower precision; suitable for non-critical biasing where cost is prioritized over regulation accuracy | Select when ±5 % voltage margin is acceptable and AEC-Q101 compliance is not required |
| MMSZ5222BS-7-F | ±5 % tolerance, 17 Ω rdiff, SOD-123 package, 5.1 V nominal, no AEC-Q101 | Higher regulation stiffness but larger footprint and unqualified for automotive use | Choose only for non-automotive consumer applications requiring ultra-low rdiff and higher continuous power |
Compared with BZX84J-B5V1,115, the ±2 % BZX84-C5V1,115 trades precision for cost, while MMSZ5222BS-7-F offers superior regulation but lacks automotive qualification and occupies more board area - making the BZX84J-B5V1,115 optimal for space-constrained, safety-critical automotive voltage references.

FAQ
What is the maximum continuous forward current for BZX84J-B5V1,115?
The absolute maximum forward current is 250 mA per Absolute Maximum Ratings (Table 5). However, sustained forward conduction is not intended in Zener operation; this rating ensures robustness during handling, testing, or fault conditions where anode-to-cathode polarity may be inadvertently applied.
How does the −2.7 to +1.2 mV/K temperature coefficient affect regulation accuracy over temperature?
This coefficient means the Zener voltage shifts by up to ±1.2 mV per °C rise above 25 °C, resulting in approximately ±102 mV drift over a 150 °C junction range. For systems requiring tighter stability, external compensation or selection of higher-voltage Zeners with near-zero TC is recommended.
Can BZX84J-B5V1,115 replace BZX84-C5V1,115 in existing designs?
Yes - both share identical SOD323F package, pinout, and 5.1 V nominal voltage. The BZX84J-B5V1,115 offers tighter ±2 % tolerance and AEC-Q101 qualification, so it upgrades performance and automotive suitability without layout changes, provided the design benefits from improved regulation accuracy.
What is the thermal resistance from junction to ambient (Rth(j-a)) under standard mounting conditions?
Rth(j-a) is 230 K/W when mounted on an FR4 PCB with single-sided 1 cm² copper pad on the cathode side (Table 6). This value assumes natural convection cooling and defines the temperature rise per watt of dissipated power - critical for thermal derating in enclosed enclosures.
