Product details
Overview
BZX79-B7V5,113 from Nexperia is a ±2% tolerance Zener voltage regulator diode in a hermetically sealed SOD27 (DO-35) glass package, rated for 7.5 V nominal Zener voltage at 5 mA test current, 30 Ω typical differential resistance, and 500 mW total power dissipation at 50 °C ambient. It serves as a precision low-power voltage reference in analog sensor signal conditioning circuits.
For engineers reviewing the BZX79-B7V5,113 datasheet, BZX79-B7V5,113 pinout, BZX79-B7V5,113 application, or BZX79-B7V5,113 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal coefficient (+2.5 to +5.3 mV/K), reverse leakage (<1 μA at 5 V), junction-to-ambient thermal resistance (380 K/W), and non-repetitive surge capability (150 A peak reverse current).
Technical Context
This device operates in reverse-biased Zener breakdown mode with tightly controlled voltage regulation across 1 mA to 20 mA operating current range. Its 7.5 V nominal Zener voltage exhibits a positive temperature coefficient of +4.0 mV/K at 5 mA, enabling stable reference performance over −65 °C to +200 °C junction temperature range.
The SOD27 package provides hermetic glass sealing and axial leads optimized for through-hole mounting on PCBs without metallization pads. Thermal design relies on junction-to-tie-point resistance (300 K/W) and junction-to-ambient resistance (380 K/W) under defined lead length constraints (≤8 mm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.35 V to 7.65 V at IZ = 5 mA - ensures ±2% regulation accuracy for precision reference designs |
| Differential Resistance (rdif) | 30 Ω typical at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Leakage Current (IR) | <1 μA at VR = 5 V - minimizes quiescent power loss in battery-powered references |
| Total Power Dissipation (Ptot) | 500 mW at Tamb = 50 °C - defines maximum continuous DC power handling under standard PCB mounting |
| Non-repetitive Peak Reverse Current (IZSM) | 150 A at tp = 100 μs - supports transient overvoltage clamping in ESD-protected interfaces |
| Temperature Coefficient (SZ) | +4.0 mV/K typical at IZ = 5 mA - enables predictable drift compensation in temperature-critical references |
| Junction-to-Ambient Thermal Resistance (Rth j-a) | 380 K/W - sets thermal rise per watt under standard lead-length mounting conditions |

FAQ
What is the maximum continuous forward current rating for BZX79-B7V5,113?
The BZX79-B7V5,113 has a maximum continuous forward current (IF) of 250 mA at Tamb = 25 °C. This rating applies only when operated in forward conduction mode-not during normal Zener regulation-and must be derated linearly above 25 °C ambient per the thermal resistance specification.
Can BZX79-B7V5,113 be used in surface-mount designs?
No-BZX79-B7V5,113 uses the axial-leaded SOD27 (DO-35) glass package designed exclusively for through-hole mounting. It lacks solder pads or terminations compatible with reflow or wave soldering processes. For SMT alternatives, consider Nexperia's PZM series or similar SOD-123 packaged Zeners.
What is the non-repetitive peak reverse power dissipation for this diode?
The BZX79-B7V5,113 supports up to 40 W of non-repetitive peak reverse power dissipation (PZSM) for pulse durations of 100 μs at Tj = 25 °C prior to surge. This capability is validated per Figure 3 in the datasheet and enables transient overvoltage suppression in low-energy surge events.
How does the temperature coefficient affect voltage regulation accuracy?
With a typical temperature coefficient of +4.0 mV/K at 5 mA, the BZX79-B7V5,113's Zener voltage increases by ~0.3 V over a 75 °C temperature span (e.g., −25 °C to +50 °C). Designers must account for this drift in applications requiring sub-1% reference stability across operating temperature ranges.
