Product details
Overview
BZX884S-B7V5-QYL from Nexperia is a ±2 % tolerance Zener voltage regulator diode in a leadless DFN1006BD-2 (SOD882BD) package, delivering 7.35 V to 7.65 V nominal breakdown voltage at 5 mA, with 30 Ω typical differential resistance and 5.0 mV/K temperature coefficient - used for precision voltage reference and overvoltage protection in automotive power rails.
For engineers reviewing the BZX884S-B7V5-QYL datasheet, BZX884S-B7V5-QYL pinout, BZX884S-B7V5-QYL application, or BZX884S-B7V5-QYL equivalent, this page provides verified package dimensions, cathode/anode terminal mapping, thermal resistance (340 K/W), AEC-Q101 qualification status, and automotive-grade stability data - critical for ECU voltage monitoring, sensor biasing, and CAN transceiver clamp circuits.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with tightly controlled VZ = 7.5 V ±2 % at IZ = 5 mA, exhibiting low dynamic impedance (30 Ω typ.) and positive temperature coefficient (+2.5 to +5.3 mV/K) across its operating current range. Its side-wettable flanks enable automated optical inspection (AOI) of solder joints on FR4 PCBs.
Rated for continuous operation up to 150 °C junction temperature and qualified per AEC-Q101, it supports stable regulation under transient load conditions in automotive environments - with Ptot = 365 mW at Tamb = 25 °C on standard 70 μm copper PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 7.35 V to 7.65 V at IZ = 5 mA - defines precise clamping threshold for 7.5 V rail stabilization |
| Differential Resistance rdif | 30 Ω typical at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Temperature Coefficient SZ | +2.5 mV/K to +5.3 mV/K - enables predictable drift compensation in wide-temperature automotive systems |
| Total Power Dissipation Ptot | 365 mW at Tamb = 25 °C on FR4 - sets maximum steady-state power handling on standard PCB layout |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - confirms low-loss conduction during forward-biased fault conditions |
| Junction-to-Ambient Rth(j-a) | 340 K/W in free air - determines thermal rise under derated power, critical for under-hood placement |
| Reverse Current IR | ≤ 1 μA at VR = 5.0 V - guarantees high-impedance blocking below breakdown, minimizing standby leakage |
Pinout & Package
DFN1006BD-2 (SOD882BD) ultra-small leadless package: 1.0 mm × 0.6 mm × 0.47 mm body, 0.65 mm pitch, side-wettable flanks for AOI-compatible reflow soldering. Marking bar indicates cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; accepts reverse-bias current during Zener conduction |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes current path during voltage clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics - supports 15-year vehicle lifecycle requirements |
| Side-wettable flanks (SWF) | Enables automated optical inspection of solder joint integrity without X-ray - reduces post-solder defect escape |
| ±2 % VZ tolerance | Ensures tight voltage margin control in safety-critical bias networks where ±5 % parts would cause functional margin loss |
| Low rdif (30 Ω typ.) | Maintains <±15 mV output deviation across 1–10 mA load changes - critical for ADC reference stability |
| 150 °C max junction temperature | Permits direct placement near heat-generating components (e.g., DC-DC converters) in engine control units |
Applications
| Automotive ECU Voltage Monitoring | Industrial Sensor Biasing |
|---|---|
Use Scenario: Monitoring 12 V battery rail in engine control unit to detect overvoltage events above 13.5 V. IC Role / Device Role / Timing Role: Zener clamp referenced to microcontroller ADC input, providing analog flag for firmware-triggered shutdown. Use Value: Tight 7.5 V ±2 % threshold ensures detection occurs before downstream LDOs exceed safe input limits. |
Use Scenario: Providing stable 7.5 V bias to MEMS pressure sensor bridge in industrial process controller. IC Role / Device Role / Timing Role: Precision shunt reference replacing larger 3-pin IC regulator to save board space in compact sensor module. Use Value: 30 Ω rdif limits bias voltage drift to <±30 mV over 1–5 mA sensor current variation. |
| Automotive CAN Transceiver Clamp | Power Supply Overvoltage Protection |
Use Scenario: Protecting CAN_H line against load-dump transients in vehicle infotainment gateway. IC Role / Device Role / Timing Role: Fast-acting shunt clamp placed between CAN_H and ground, absorbing surge energy during ISO 7637-2 pulse 5a. Use Value: 365 mW Ptot rating allows sustained clamping at 7.5 V for ≥100 ms without thermal runaway. |
Use Scenario: Safeguarding 5 V logic supply from accidental 12 V backfeed in multi-rail embedded system. IC Role / Device Role / Timing Role: Reverse-biased Zener connected between 5 V rail and ground, conducting only when voltage exceeds 7.5 V. Use Value: ≤1 μA IR at 5 V ensures zero static current draw during normal operation - no impact on standby power budget. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C7V5-Q | ±5 % tolerance (7.0 V–7.9 V), higher rdif (up to 80 Ω), +2.5 to +5.3 mV/K SZ | Acceptable where tighter VZ margin is not required, e.g., non-safety-critical indicator circuits | Select for cost-sensitive designs where ±5 % regulation accuracy suffices and thermal drift matching is secondary |
| MMSZ5237B-7-F | ±5 % tolerance (7.14 V–7.86 V), 30 Ω rdif, −2.5 mV/K SZ, SOD-123 package (larger, no SWF) | Lacks AEC-Q101 qualification and side-wettable flanks - unsuitable for automotive AOI production lines | Choose only for non-automotive industrial use where legacy SOD-123 footprint compatibility is mandatory |
Compared with BZX884S-C7V5-Q and MMSZ5237B-7-F, the BZX884S-B7V5-QYL delivers superior voltage accuracy and automotive qualification in a smaller, AOI-ready package - making it the sole option for new AEC-Q101-compliant designs requiring ±2 % regulation at 7.5 V.

FAQ
What is the maximum reverse current at 5.0 V for BZX884S-B7V5-QYL?
The maximum reverse current IR is ≤1 μA at VR = 5.0 V and Tj = 25 °C, confirming negligible leakage during normal operation below breakdown - essential for low-power sensor biasing and battery-backed systems where standby current must remain sub-microampere.
Can BZX884S-B7V5-QYL be used in reflow soldering processes?
Yes - it uses the DFN1006BD-2 package with side-wettable flanks, designed exclusively for reflow soldering per Nexperia's recommended footprint (1.0 mm × 0.6 mm lands, 0.4 mm solder paste stencil). Wave soldering and hand soldering are not supported due to thermal stress risks and lack of leads.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With SZ = +2.5 to +5.3 mV/K, VZ increases by approximately 415 mV over a 125 °C span - meaning regulation shifts from ~7.3 V at −40 °C to ~7.7 V at +125 °C. This predictable positive drift enables firmware compensation in closed-loop systems.
Is BZX884S-B7V5-QYL compatible with lead-free PCB assembly standards?
Yes - it is RoHS-compliant and rated for peak reflow temperatures up to 260 °C per JEDEC J-STD-020, with moisture sensitivity level (MSL) 1. The side-wettable flanks ensure reliable solder joint formation using standard SAC305 paste and nitrogen-reflow profiles.
