Product details
Overview
BZX84C13Q-7-F from Diodes Incorporated is an automotive-grade 13V Zener diode in SOT23 package, rated for 350mW power dissipation at 25°C ambient, with nominal Zener voltage 13V (12.4–14.1V range), 30Ω dynamic impedance at 5mA test current, and <0.1µA reverse leakage at 8V. It provides precision voltage regulation in low-power biasing and reference circuits for automotive control modules.
For engineers reviewing the BZX84C13Q-7-F datasheet, BZX84C13Q-7-F pinout, BZX84C13Q-7-F application, or BZX84C13Q-7-F equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (357°C/W), AEC-Q101 qualification, SOT23 footprint compatibility, and reverse leakage performance at VR = 8V.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown when biased above its specified Zener voltage. Its planar die construction ensures stable breakdown characteristics and low temperature coefficient (±7.0 mV/°C) across the operating range.
Designed for surface-mount automated assembly, it features matte tin-plated alloy 42 leads, UL 94V-0 molded plastic case, and moisture sensitivity level 1 - enabling reflow compatibility without preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13V nominal (12.4–14.1V range at IZT = 5mA); defines stable regulation point for reference/bias networks |
| Power Dissipation (PD) | 350mW at TA = 25°C; derates linearly above 25°C per 357°C/W thermal resistance |
| Zener Impedance (ZZT) | 30Ω max at IZT = 5mA; determines output voltage stability under varying load current |
| Reverse Leakage (IR) | ≤0.1µA at VR = 8V; ensures minimal quiescent current in high-impedance sensing paths |

Package: SOT23 - three-terminal plastic surface-mount package with cathode-marked lead (pin 1), anode (pin 2), and cathode (pin 3). Standard pin 1 orientation marked by beveled edge or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode Mark) | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| Pin 2 | Anode | Ground or low-side reference point; completes reverse-bias path for regulation |
| Pin 3 | Cathode (common with Pin 1) | Electrically tied to Pin 1 in standard SOT23 Zener configuration; dual-cathode layout for mechanical robustness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4687T1G | 13V nominal, 500mW rating, SOD-123 package, RθJA = 300°C/W, IR = 0.1µA @ 8V | Larger footprint; higher power handling but lower thermal efficiency in dense layouts | Select when higher surge energy absorption is required and board space permits SOD-123 |
| BZX84-C13-E3-08 | 13V nominal, 350mW, SOT23, AEC-Q101 not claimed, IR = 0.1µA @ 8V, same Zener impedance | Industrial-grade only; lacks automotive qualification and green compound compliance | Select for cost-sensitive non-automotive applications where AEC-Q101 is not mandated |
Compared with MMSZ4687T1G and BZX84-C13-E3-08, BZX84C13Q-7-F uniquely combines AEC-Q101 qualification, halogen-free packaging, and SOT23 footprint - making it the only option qualified for automotive underhood use with zero compromise on board area or environmental compliance.

FAQ
What is the maximum junction temperature for BZX84C13Q-7-F?
The absolute maximum junction temperature is +150°C, with continuous operation supported from −65°C to +150°C ambient. Derating begins at 25°C using RθJA = 357°C/W; at 85°C ambient, maximum allowable power drops to approximately 200mW.
Is BZX84C13Q-7-F compatible with lead-free reflow profiles?
Yes - it is fully RoHS 3 compliant and qualified for standard lead-free reflow (J-STD-020, Level 1), with matte tin-plated leads solderable per MIL-STD-202, Method 208. No preconditioning is required due to its moisture sensitivity level 1 rating.
How does the "Q" suffix in BZX84C13Q-7-F affect specifications?
The "Q" denotes AEC-Q101 qualification and green (halogen/antimony-free) molding compound. Electrically and thermally identical to non-Q variants, but subjected to additional stress testing (HTOL, TCT, ESD) and manufactured with environmentally compliant materials per Diodes' Green policy.
Can BZX84C13Q-7-F replace BZX84C12 or BZX84C15 in existing designs?
No - while pin-compatible, the 13V Zener voltage is specific to this variant. Substituting with 12V or 15V parts alters regulation setpoint by ≥1V, potentially violating system-level voltage margin requirements in automotive sensors or references. Always verify VZ tolerance and temperature coefficient alignment before substitution.
