Product details
Overview
BZT52C3V6Q-7-F from Diodes Incorporated is an AEC-Q101 qualified surface-mount Zener diode with nominal zener voltage 3.6 V (±5.6%), 500 mW power dissipation at TL = +75°C, and 90 Ω maximum zener impedance at 5 mA test current - used for precision voltage regulation and overvoltage protection in automotive sensor signal conditioning circuits.
For engineers reviewing the BZT52C3V6Q-7-F datasheet, BZT52C3V6Q-7-F pinout, BZT52C3V6Q-7-F application, or BZT52C3V6Q-7-F equivalent, key selection criteria include zener voltage tolerance, thermal resistance (RθJL = 150 °C/W), reverse leakage at VR = 1.0 V (≤5 µA), and SOD123 automotive-grade packaging compliance.
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 breakdown characteristics and low dynamic impedance across the 5 mA test current range.
The device exhibits a negative temperature coefficient of –3.5 mV/°C, enabling predictable drift compensation in bias networks. It is rated for operation from –65 °C to +150 °C and supports automated SMT assembly via matte tin–plated alloy 42 leadframe.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.6 V nominal, 3.4–3.8 V range at IZT = 5 mA - defines regulated output voltage tolerance in feedback or clamp circuits. |
| Power Dissipation | 500 mW at TL = +75°C - sets maximum continuous power handling on PCB with defined thermal pad layout. |
| Zener Impedance (ZZT) | 90 Ω max at f = 1 kHz, IZT = 5 mA - determines AC regulation stability and ripple rejection capability. |
| Reverse Leakage (IR) | ≤5 µA at VR = 1.0 V - ensures minimal quiescent current draw in low-power standby or sensing paths. |
| Thermal Resistance (RθJL) | 150 °C/W - quantifies junction-to-lead heat transfer efficiency for thermal design margining in automotive modules. |
| Operating Temperature | –65 °C to +150 °C - enables deployment in engine control units, transmission sensors, and under-hood electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4685-7-F | Zener voltage 3.6 V, but rated only for commercial grade (non-AEC-Q101); RθJA = 350 °C/W vs. 338 °C/W. | Lacks automotive qualification; unsuitable for under-hood or safety-critical modules. | Select when cost-sensitive consumer or industrial designs do not require AEC-Q101 validation. |
| BZX84-C3V6 | SOT-23 package (larger footprint), 300 mW PD at TA = 25°C, 100 Ω ZZT max - lower power and higher impedance than BZT52C3V6Q-7-F. | Higher thermal resistance limits use in thermally constrained layouts; less stable regulation at elevated temperatures. | Prefer where existing SOT-23 board space exists and 3.6 V regulation at ≤10 mA is sufficient. |
Compared with MMSZ4685-7-F and BZX84-C3V6, BZT52C3V6Q-7-F delivers superior thermal performance (RθJL = 150 °C/W), automotive qualification, and tighter zener impedance - making it optimal for high-reliability, space-constrained, and thermally demanding applications.

FAQ
What is the maximum reverse leakage current for BZT52C3V6Q-7-F at 1.0 V?
The maximum reverse leakage current (IR) is 5 µA when reverse voltage (VR) is applied at 1.0 V, measured at TA = +25°C. This value remains stable across the full operating temperature range and confirms suitability for ultra-low-power bias networks in battery-operated automotive modules.
Is BZT52C3V6Q-7-F compatible with lead-free reflow soldering profiles?
Yes - the device uses matte tin finish annealed over alloy 42 leadframe and is fully compatible with IPC/JEDEC J-STD-020D-compliant lead-free reflow profiles, including peak temperatures up to 260°C. Its moisture sensitivity level is rated Class 1, eliminating bake requirements prior to assembly.
How does the –3.5 mV/°C temperature coefficient affect circuit design?
The negative temperature coefficient means VZ decreases by 3.5 mV per degree Celsius rise. In precision references, this requires compensation via complementary positive-TC components or calibration algorithms - especially critical in engine control units operating from –40 °C to +150 °C.
Can BZT52C3V6Q-7-F be used as a substitute for BZT52C3V6-7-F in automotive designs?
No - the "Q" suffix denotes AEC-Q101 qualification, while the non-Q version lacks automotive stress testing and reliability validation. Substitution would violate functional safety requirements (e.g., ISO 26262) and invalidate qualification documentation for Tier-1 suppliers.
