Product details
Overview
BZT52C7V5-13 from Diodes Incorporated is a surface-mount Zener diode with nominal 7.5 V zener voltage, 5 mA test current, and ±0.5 V tolerance (7.0–7.9 V), rated for 500 mW power dissipation at TL = +75°C and packaged in SOD123. It provides precise voltage regulation in low-power supply rails, overvoltage protection circuits, and reference voltage generation for analog sensors and ADC biasing.
For engineers reviewing the BZT52C7V5-13 datasheet, BZT52C7V5-13 pinout, BZT52C7V5-13 application, or BZT52C7V5-13 equivalent, key selection criteria include zener voltage accuracy at 5 mA, low dynamic impedance (15 Ω @ 5 mA), temperature coefficient (+2.5 mV/°C), reverse leakage (≤0.1 µA @ 5.3 V), and automotive-grade AEC-Q101 qualification.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its planar die construction ensures consistent breakdown characteristics and long-term stability, while the SOD123 package supports automated placement and reflow soldering.
The device exhibits a positive temperature coefficient of +2.5 mV/°C, enabling predictable drift compensation in multi-diode reference networks. With 15 Ω zener impedance at 5 mA and ≤0.1 µA reverse current at 5.3 V, it delivers tight regulation for precision analog front-ends and low-current sensing interfaces.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5227BS-7-F | Zener voltage 3.0 V, 200 mW PD, SOT-23 package, 100 Ω ZZT | Lower voltage, lower power, higher impedance - suited for logic-level clamping, not precision 7.5 V reference | Select only if 3.0 V regulation and SOT-23 footprint are required; not drop-in for BZT52C7V5-13's 7.5 V function |
| BZX84-C7V5-7-F | 7.5 V nominal, 350 mW PD, SOT-23, 30 Ω ZZT, no AEC-Q101 qualification | Same voltage but lower power rating and unqualified for automotive use; higher impedance than BZT52C7V5-13 | Acceptable for commercial-grade 7.5 V reference where AEC-Q101 and 500 mW are not mandatory |
Compared with MMBZ5227BS-7-F and BZX84-C7V5-7-F, BZT52C7V5-13 offers superior voltage accuracy, higher power handling, lower impedance, and automotive qualification - making it the preferred choice for safety-critical and thermally demanding regulation tasks.

FAQ
What is the maximum reverse voltage (VR) that BZT52C7V5-13 can withstand before breakdown?
The BZT52C7V5-13 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; the device is not rated for continuous operation above 7.9 V in reverse bias. Its reverse leakage remains ≤0.1 µA at 5.3 V, confirming sharp knee behavior near nominal VZ.
Is BZT52C7V5-13 suitable for use in automotive applications?
Yes - BZT52C7V5-13 is explicitly qualified to AEC-Q101 standards, with operating temperature range of –65°C to +150°C and validation for high-reliability automotive subsystems including body electronics, lighting controls, and sensor interfaces.
How does the SOD123 package affect thermal performance compared to larger packages?
The SOD123 package delivers RθJA = 338°C/W on FR-4 with 1-inch copper pad, limiting ambient-rated power to 370 mW at +25°C. However, its RθJL = 150°C/W enables 500 mW operation when lead temperature is held at +75°C - making thermal design dependent on PCB copper area and airflow, not just ambient conditions.
Can BZT52C7V5-13 replace older Zener diodes like 1N4733A in new designs?
No - the 1N4733A is a through-hole 5 W device in DO-41 package with 5.1 V rating and different thermal profile. BZT52C7V5-13 is a 7.5 V, surface-mount, 500 mW AEC-Q101-qualified part. Direct replacement requires verifying voltage match, power margin, PCB layout compatibility, and qualification requirements for the target application.
