Product details
Overview
BZT52C9V1-13-F from Diodes Incorporated is a surface-mount Zener diode with a nominal zener voltage of 9.1 V, ±5.5% tolerance (8.5–9.6 V), 500 mW power dissipation at TL = +75°C, 370 mW at TA = +25°C, and 15 Ω maximum zener impedance at 5 mA test current - used for precision voltage regulation and overvoltage protection in low-power DC rails.
For engineers reviewing the BZT52C9V1-13-F datasheet, BZT52C9V1-13-F pinout, BZT52C9V1-13-F application, or BZT52C9V1-13-F equivalent, key selection criteria include zener voltage accuracy, thermal resistance (RθJL = 150 °C/W), SOD123 package compatibility, reverse leakage (<0.5 µA @ 7.0 V), 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 breakdown characteristics, while the SOD123 package enables high-density PCB layouts and compatibility with automated reflow assembly.
It delivers regulated output across a 5 mA test current with <15 Ω dynamic impedance and exhibits a positive temperature coefficient of +3.8 mV/°C - enabling predictable drift compensation in multi-diode reference networks and low-drift analog sensing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.1 V nominal, 8.5–9.6 V range at 5 mA - defines precise clamping threshold for 9 V rail stabilization |
| Power Dissipation | 370 mW at +25°C ambient - sets max continuous power in standard FR-4 layout with 1-inch copper pad |
| Zener Impedance (ZZT) | ≤15 Ω at IZT = 5 mA - ensures minimal output voltage variation under load transients |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 7.0 V - guarantees low quiescent current in battery-powered voltage monitor circuits |
| Thermal Resistance (RθJL) | 150 °C/W - enables reliable operation up to +150°C junction temperature with proper lead heat sinking |
| Temperature Coefficient | +3.8 mV/°C - allows accurate prediction of voltage drift over industrial temperature range (−65°C to +150°C) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240B-7-F | Zener voltage 10 V (9.4–10.6 V), 350 mW PD at +25°C, RθJA = 357 °C/W | Higher VZ and lower power rating reduce margin in 9 V rail clamping; better suited for 10 V references | Select when 10 V regulation is required and thermal budget permits higher junction rise |
| BZX84-C9V1 | SOT-23 package, same 9.1 V VZ, but 300 mW PD, RθJA = 300 °C/W, no AEC-Q101 qualification | Larger thermal resistance and non-automotive qualification limit use in under-hood environments | Prefer for cost-sensitive consumer applications where AEC-Q101 and SOD123 board space are not required |
Compared with MMBZ5240B-7-F and BZX84-C9V1, BZT52C9V1-13-F offers tighter VZ tolerance, higher power derating capability, and automotive qualification - making it optimal for safety-critical 9 V rail regulation where thermal stability and reliability are prioritized over footprint size or unit cost.

FAQ
What is the maximum reverse leakage current for BZT52C9V1-13-F at 7.0 V?
The maximum reverse leakage current is 0.5 µA at VR = 7.0 V and TA = +25°C, as specified in the Electrical Characteristics table. This low leakage ensures minimal standby power loss in battery-backed circuits and maintains accuracy in high-impedance reference nodes.
Is BZT52C9V1-13-F qualified for automotive applications?
Yes - BZT52C9V1-13-F is qualified to AEC-Q101 standards, confirming its suitability for automotive applications including engine control units, infotainment power supplies, and ADAS sensor interfaces where reliability under thermal cycling and vibration is critical.
How does the SOD123 package affect thermal performance compared to SOT-23?
The SOD123 package provides lower thermal resistance (RθJL = 150 °C/W) than typical SOT-23 Zeners due to its larger leadframe cross-section and optimized copper pad layout - enabling 370 mW dissipation at +25°C versus ~300 mW for comparable SOT-23 devices.
Can BZT52C9V1-13-F be used in parallel for higher power handling?
No - Zener diodes should not be paralleled without individual ballast resistors due to mismatched breakdown voltages causing current hogging. For higher power, select a single higher-rated device like the 1 W BZX84-B9V1 or use active regulation instead.
