Product details
Overview
BZT52C10TQ-7-F from Diodes Incorporated is a surface-mount Zener diode with nominal 10 V zener voltage (9.4–10.6 V range at 5 mA), 300 mW power dissipation, 20 Ω maximum zener impedance at 5 mA, and SOD523 package. It provides precision voltage regulation and overvoltage protection in low-power analog rails, sensor biasing, and reference circuits for automotive and industrial control modules.
For engineers reviewing the BZT52C10TQ-7-F datasheet, BZT52C10TQ-7-F pinout, BZT52C10TQ-7-F application, or BZT52C10TQ-7-F equivalent, key selection criteria include zener voltage tolerance (±6%), thermal resistance (417 °C/W), reverse leakage (0.2 µA @ 7.0 V), cathode band polarity marking, and AEC-Q200-compatibility readiness via Q-suffix qualification path.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp or regulate voltage across its terminals. Its behavior is defined by a stable 10 V nominal zener voltage at 5 mA test current, with temperature coefficient of +4.5 mV/°C and typical capacitance of ~15 pF at 1 V reverse bias.
The SOD523 package enables high-density PCB layouts while maintaining thermal performance under 300 mW continuous dissipation. Its flat-lead construction supports automated assembly and meets JEDEC reliability standards for high-reliability applications including automotive body electronics and industrial sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240B-7-F | Same 10 V nominal zener, but SOT-23 package (larger footprint, 350 mW PD) and 30 Ω ZZT | Higher power handling suits higher-current biasing; less suitable for ultra-thin modules | Select when thermal margin >50 mW is required and board space permits 3.0 × 1.4 mm footprint |
| BZX84-C10-7-F | 10 V zener in SOT-23, 350 mW PD, but 30 Ω ZZT and 0.5 µA IR @ 7 V | Higher leakage reduces accuracy in low-current sensor references | Prefer for general-purpose clamping where leakage sensitivity is not critical |
Compared with MMBZ5240B-7-F and BZX84-C10-7-F, BZT52C10TQ-7-F offers tighter voltage tolerance (±6% vs ±10%), lower leakage (0.2 µA vs ≥0.5 µA), and smaller SOD523 footprint - making it optimal for space- and precision-constrained automotive and industrial sensing nodes.

FAQ
What is the maximum reverse voltage before breakdown for BZT52C10TQ-7-F?
The device exhibits sharp reverse breakdown at 10 V nominal, with guaranteed range of 9.4–10.6 V at 5 mA test current. Below 7.0 V, reverse leakage remains ≤0.2 µA; no defined "maximum non-breakdown voltage" is specified - operation above 10.6 V initiates controlled conduction per zener characteristic.
Is BZT52C10TQ-7-F qualified to AEC-Q200?
The Q-suffix indicates qualification readiness: Diodes offers automotive-grade variants (e.g., BZT52C10TQ-7-F) manufactured in IATF 16949-certified facilities and PPAP-capable. While this specific part number is not individually listed in AEC-Q200 reports, its Q-suffix family meets AEC-Q200 stress test requirements per Diodes' automotive product definitions.
Can BZT52C10TQ-7-F replace through-hole 1N4740A in PCB redesigns?
No - 1N4740A is a 10 V, 1 W through-hole Zener in DO-41 package. BZT52C10TQ-7-F delivers only 300 mW in SOD523. Direct replacement requires verifying power dissipation, thermal layout, and current capability; it is suitable only for low-power signal-level applications, not power rail regulation.
What does the "Q-7-F" suffix indicate in BZT52C10TQ-7-F?
"Q" denotes automotive qualification readiness per AEC-Q200, "7" specifies 3,000-unit tape-and-reel packaging, and "F" indicates halogen- and antimony-free "Green" compliance per Diodes' definition (<900 ppm Br/Cl, <1000 ppm Sb). The full suffix confirms JEDEC-compliant, RoHS 3–compliant, auto-qualified packaging format.
