Product details
Overview
BZV90-C4V7,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation in power supply feedback paths. It delivers a nominal Zener voltage of 4.7 V (min 4.4 V, max 5.0 V) at 5 mA test current, with differential resistance ≤80 Ω, temperature coefficient −1.4 mV/K (typ), and total power dissipation up to 1500 mW. It is used in industrial power supplies requiring stable low-voltage references.
For engineers reviewing the BZV90-C4V7,115 datasheet, BZV90-C4V7,115 pinout, BZV90-C4V7,115 application, or BZV90-C4V7,115 equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (83.3 K/W), non-repetitive peak reverse power (40 W), junction temperature limit (150 °C), and SOT223 thermal pad layout compatibility.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ and low dynamic impedance, enabling stable voltage clamping and reference generation under varying load and temperature conditions. Its E24-standard 4.7 V rating and ±5% tolerance support cost-effective, high-yield designs in regulated DC-DC feedback loops.
The SOT223 package features an exposed collector pad (Pin 3) for enhanced thermal conduction, allowing sustained 1.5 W dissipation when mounted on 2 cm² double-sided FR4 copper. Its 4-pin configuration (anode-cathode-anode-cathode) supports dual-anode layout flexibility in PCB routing while maintaining mechanical robustness.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C4V7 | Same VZ (4.4–5.0 V), but SOT23 package; Ptot = 300 mW; rdif ≤100 Ω; no thermal pad | Limited to ≤300 mW continuous use; unsuitable for >0.3 W reference loads or surge-heavy environments | Select when board space is critical and power demand is <300 mW; avoid in thermally demanding or high-surge applications. |

FAQ
What is the maximum continuous forward current for BZV90-C4V7,115?
The absolute maximum continuous forward current (IF) is 400 mA at Tamb = 25 °C. However, this device is intended for reverse-bias Zener operation; forward conduction is not its functional mode and should be avoided in circuit design to prevent parameter shift or reliability degradation.
Can BZV90-C4V7,115 replace a 5.1 V Zener in an existing design?
No-BZV90-C4V7,115 has a nominal Zener voltage of 4.7 V (4.4–5.0 V range), not 5.1 V. Substituting it for a 5.1 V part would shift feedback thresholds by ~0.4 V, potentially causing output overvoltage or regulation failure. Use BZV90-C5V1,115 for 5.1 V applications.
Is the SOT223 thermal pad (Pin 3) electrically isolated?
No-Pin 3 is internally connected to Pin 1 (anode). The exposed pad serves exclusively for thermal conduction and mechanical anchoring; it must be soldered to a grounded or low-impedance anode copper pour, not left floating or connected to cathode potential.
Does BZV90-C4V7,115 meet AEC-Q200 for automotive use?
No-the BZV90 series is not AEC-Q200 qualified. While widely used in automotive body electronics, it lacks formal stress-test validation per AEC-Q200 Rev D. For Q200-compliant designs, consider Nexperia's Automotive Qualified (AQ) Zener series such as PZUxxB2A or BZX384-A4V7.
