Product details
Overview
BZT52C7V5-7-F from Diodes Incorporated is a surface-mount 7.5 V Zener diode in SOD123 package, rated for 500 mW power dissipation at TL = +75°C and 370 mW at TA = +25°C, with 15 Ω typical Zener impedance at 5 mA test current and ±5% voltage tolerance (7.0–7.9 V), widely used for voltage regulation and overvoltage protection in DC power rails of industrial control modules.
For engineers reviewing the BZT52C7V5-7-F datasheet, BZT52C7V5-7-F pinout, BZT52C7V5-7-F application, or BZT52C7V5-7-F equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJA = 338 °C/W), reverse leakage at VR = 5.3 V (≤1.0 µA), temperature coefficient (+2.5 mV/°C), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its planar die construction ensures consistent electrical performance and high reliability across production lots.
The device exhibits low dynamic impedance (15 Ω @ 5 mA) and tight voltage tolerance (±5%), enabling precise clamping in feedback loops and analog reference circuits. Its SOD123 package supports automated pick-and-place assembly and provides adequate thermal dissipation for medium-current regulation tasks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.5 V nominal, 7.0–7.9 V range at 5 mA - defines clamping threshold for overvoltage protection |
| Power Dissipation (PD) | 370 mW @ TA = +25°C - limits continuous operation without heatsinking on standard FR-4 PCB |
| Zener Impedance (ZZT) | 15 Ω @ IZT = 5 mA - ensures minimal voltage deviation under load transients |
| Reverse Leakage (IR) | ≤1.0 µA @ VR = 5.3 V - guarantees low quiescent current in standby regulation |
| Temperature Coefficient | +2.5 mV/°C - indicates positive drift; critical for temperature-stable references |
| Thermal Resistance (RθJA) | 338 °C/W - determines junction temperature rise per watt on standard layout |
Pinout & Package
Package: SOD123 - surface-mount plastic case with cathode band marking, 0.010 g weight, UL 94V-0 flammability rating, and matte tin-plated Alloy 42 leadframe for reliable solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to lower-potential node; reverse-biased operation requires cathode at higher potential |
| Cathode | Zener breakdown terminal / voltage clamp output | Marked by band; connected to regulated rail or protection point; carries full Zener current during clamping |
Key Features
| Feature | Design Value |
|---|---|
| Planar die construction | Ensures repeatable Zener voltage distribution and long-term stability under thermal cycling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5227BS-7-F | Same 7.5 V nominal, but SOT-23 package; RθJA = 300 °C/W; 200 mW PD @ TA | Higher power density but lower absolute power handling; less suitable for sustained 370 mW loads | Select when board space is constrained and thermal management via copper pour is feasible |
| 1N4734A | Through-hole DO-41; 1 W PD; ±5% tolerance; 10 Ω ZZT; no AEC-Q101 qualification | Higher power capability but incompatible with SMT automation and automotive qualification requirements | Select only for prototyping or non-automated, non-automotive legacy designs |
Compared with MMBZ5227BS-7-F and 1N4734A, BZT52C7V5-7-F uniquely balances SMT compatibility, AEC-Q101 reliability, and 370 mW continuous regulation capacity in a low-profile SOD123 footprint-making it optimal for volume-manufactured automotive and industrial PCBs.

FAQ
What is the maximum reverse voltage (VR) at which leakage current is specified for BZT52C7V5-7-F?
The datasheet specifies IR ≤ 1.0 µA at VR = 5.3 V, which is 70% of the nominal Zener voltage (7.5 V). This test condition ensures the diode remains in pre-breakdown region while verifying low leakage essential for battery-powered systems.
Can BZT52C7V5-7-F be used in place of a 6.8 V Zener diode in an existing design?
No-replacing a 6.8 V Zener (e.g., BZT52C6V8) with BZT52C7V5-7-F shifts the clamping threshold by +0.7 V, potentially causing undervoltage lockout or incorrect regulation. The 7.5 V device is not a functional substitute unless circuit tolerances accommodate the higher voltage.
Is the SOD123 package of BZT52C7V5-7-F compatible with standard reflow profiles?
Yes-the SOD123 package is qualified for lead-free reflow per J-STD-020, with Moisture Sensitivity Level 1, meaning it can be placed directly into reflow ovens without baking, supporting standard IPC/JEDEC profiles including peak temperatures up to 260 °C.
Does BZT52C7V5-7-F meet automotive qualification standards?
Yes-this part is explicitly qualified to AEC-Q101 Rev. D for high-reliability automotive applications, including stress testing for temperature cycling, humidity bias, and mechanical shock, as confirmed in Diodes' DS18004 Rev. 38 documentation.
