Product details
Overview
BZT52C7V5S-7 from Diodes Incorporated is a surface-mount Zener diode with nominal 7.5 V zener voltage (±0.5 V tolerance), 5 mA test current, 15 Ω maximum zener impedance at 5 mA, 0.7 µA maximum reverse leakage at 5.0 V, and 200 mW power dissipation in SOD323 package. It provides precision voltage regulation in low-power analog monitoring and reference circuits.
For engineers reviewing the BZT52C7V5S-7 datasheet, BZT52C7V5S-7 pinout, BZT52C7V5S-7 application, or BZT52C7V5S-7 equivalent, key selection criteria include zener voltage stability over temperature (±2.5 mV/°C coefficient), low leakage at sub-breakdown bias, thermal resistance (625 °C/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and supply conditions. Its planar die construction ensures consistent breakdown characteristics, while the SOD323 package enables high-density PCB layouts and compatibility with automated reflow assembly.
The device exhibits a positive temperature coefficient of +2.5 mV/°C near 7.5 V, enabling predictable drift compensation in reference designs. With 15 Ω dynamic impedance at 5 mA and <0.7 µA IR at VR = 5.0 V, it delivers tight regulation for low-current biasing and sensing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.5 V nominal, 7.0–7.9 V range at IZT = 5 mA - defines regulated output voltage tolerance |
| Power Dissipation (PD) | 200 mW - limits continuous operating current to ~26 mA at 7.5 V |
| Zener Impedance (ZZT) | 15 Ω max at 1 kHz, 5 mA - determines regulation stiffness under load transients |
| Reverse Leakage (IR) | 0.7 µA max at VR = 5.0 V - ensures minimal error current in high-impedance reference nodes |
| Temperature Coefficient | +2.5 mV/°C - quantifies voltage drift per degree Celsius rise above 25 °C |
| Thermal Resistance (RθJA) | 625 °C/W - sets junction-to-ambient temperature rise per watt dissipated |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5227BS-7-F | Same SOD323 package, 3.0 V zener voltage, 100 Ω ZZT, higher leakage (150 µA @ 2.5 V) | Not suitable for 7.5 V reference; used in low-voltage logic clamping | Select only if system requires 3.0 V regulation and can tolerate higher impedance |
| BZX84-C7V5 | SOT23 package, same 7.5 V rating, 30 Ω ZZT, 1.0 µA leakage @ 5.0 V, non-AEC-Q101 | Larger footprint, lower thermal performance (RθJA = 350 °C/W), not automotive-qualified | Acceptable for commercial-grade designs where space and reliability requirements are less stringent |
Compared with MMBZ5227BS-7-F and BZX84-C7V5, BZT52C7V5S-7 offers optimal balance of 7.5 V precision, low 15 Ω impedance, AEC-Q101 compliance, and compact SOD323 form factor-making it preferred for automotive and high-accuracy industrial references.

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZT52C7V5S-7 has a nominal zener voltage of 7.5 V with a guaranteed range of 7.0–7.9 V at 5 mA test current. Breakdown occurs within this range; operation below 5.0 V reverse bias yields <0.7 µA leakage, confirming stable pre-breakdown behavior.
Is this part suitable for use in automotive applications?
Yes-BZT52C7V5S-7 is explicitly qualified to AEC-Q101 standards, including temperature cycling, humidity testing, and mechanical shock validation. Its SOD323 package and green material composition meet automotive environmental and reliability requirements.
How does thermal resistance affect its performance in a PCB layout?
With RθJA = 625 °C/W, dissipating 100 mW raises junction temperature by 62.5 °C above ambient. To stay within -65°C to +150°C operating range, keep ambient below +87.5°C or reduce power; recommended pad layout per Diodes' package outline minimizes thermal resistance.
Can this Zener diode replace a 7.5 V linear regulator in low-current applications?
No-it lacks current-limiting or regulation circuitry. While it maintains ~7.5 V across its terminals when reverse-biased above breakdown, it requires external series resistance to limit current and cannot source load current like a regulator. Use only as a shunt reference or clamp.
