Product details
Overview
BZX84C24Q-13-F from Diodes Incorporated is a 24V, 350mW surface-mount Zener diode in SOT23 package, rated for 5mA test current with 22.8–25.6V zener voltage range, 70Ω dynamic impedance at 5mA, and 0.1µA maximum reverse leakage at 18.4V. It provides precision voltage regulation in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the BZX84C24Q-13-F datasheet, BZX84C24Q-13-F pinout, BZX84C24Q-13-F application, or BZX84C24Q-13-F equivalent, this page delivers verified electrical specs, automotive-grade qualification status, thermal derating behavior, and direct replacement guidance for board-level design and BOM validation.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its 24V nominal zener voltage is specified at 5mA test current (IZT), with ±5% tolerance (22.8–25.6V) and a negative temperature coefficient of −3.5mV/°C.
The device uses planar die construction and matte tin-plated alloy 42 leadframe for solderability and reliability. It is qualified to AEC-Q101 standards, moisture sensitivity level 1, and fully RoHS-compliant with halogen- and antimony-free green molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 24V nominal, 22.8–25.6V range at 5mA - defines regulated output voltage window under standard bias |
| Power Dissipation | 350mW at TA = +25°C - sets maximum continuous power handling on FR-4 PCB with recommended pad layout |
| Zener Impedance (ZZT) | 70Ω at 5mA - determines regulation stiffness and AC ripple rejection in reference applications |
| Reverse Leakage (IR) | 0.1µA max at VR = 18.4V - ensures minimal quiescent current in high-impedance bias networks |
| Thermal Resistance (RθJA) | 357°C/W - defines junction-to-ambient temperature rise per watt dissipated under ambient-terminal condition |
| Temperature Coefficient | −3.5mV/°C - quantifies voltage drift with temperature; enables compensation in precision references |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5248B-TP | 24V nominal, 500mW rating, 30Ω ZZT at 5mA, SOD-123 package | Larger thermal mass but incompatible SOT23 footprint; higher power handling | Select when board layout allows SOD-123 and >350mW surge capability is required |
| BZX84-C24,115 | Same 24V spec, 350mW, SOT23, but non-automotive grade (no AEC-Q101) | Lacks automotive qualification; not suitable for vehicular environments | Select for cost-sensitive industrial designs where AEC-Q101 is not mandated |

FAQ
What is the maximum power dissipation for BZX84C24Q-13-F at 85°C ambient?
At 85°C ambient, the device's power dissipation must be derated linearly from 350mW at 25°C using the 357°C/W RθJA value. The allowable power is 350mW × (1 − (85 − 25)/357) ≈ 252mW. This ensures junction temperature remains within −65°C to +150°C limits.
Is BZX84C24Q-13-F compatible with lead-free reflow profiles?
Yes. The device features matte tin plating over alloy 42 leadframe and is qualified for lead-free reflow per J-STD-020. Its moisture sensitivity level is 1, eliminating bake requirements prior to assembly. Peak reflow temperature up to 260°C is supported.
How does the −3.5mV/°C temperature coefficient affect long-term reference stability?
The negative TC causes the zener voltage to decrease by 3.5mV per °C rise. Over a −40°C to +125°C range, total drift is approximately 578mV (165°C × 3.5mV/°C), resulting in ~2.4% deviation from 24V nominal. For high-stability references, this requires external compensation or selection of TC-matched devices.
What distinguishes the "Q" suffix in BZX84C24Q-13-F from standard BZX84C24-13-F?
The "Q" denotes AEC-Q101 qualification and automotive-grade screening, including extended temperature cycling, high-temperature operating life, and biased HAST testing. Standard versions lack this qualification and are intended for industrial/commercial use only.
