Product details
Overview
BZX84C13W-7-F from Diodes Incorporated is a 13 V, 200 mW surface-mount Zener diode in SOT-323 package, rated for 5 mA test current with 12.4–14.1 V zener voltage tolerance, 30 Ω max zener impedance at IZT, and 0.1 µA max reverse leakage at 8.0 V. It provides precision voltage regulation in low-power biasing and reference circuits.
For engineers reviewing the BZX84C13W-7-F datasheet, BZX84C13W-7-F pinout, BZX84C13W-7-F application, or BZX84C13W-7-F equivalent, key selection criteria include zener voltage tolerance, dynamic impedance at 5 mA, thermal resistance (625 K/W), operating temperature range (–65 to +125 °C), and RoHS-compliant green molding compound construction.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load or supply conditions. Its planar die construction ensures consistent parametric performance and low leakage, while the SOT-323 package enables high-density PCB layouts in space-constrained applications.
The device exhibits a positive temperature coefficient of +7.0 to +11.0 mV/°C at 5 mA, enabling predictable drift behavior in temperature-sensitive references. It is characterized with short-duration pulse testing to minimize self-heating effects during parameter measurement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.0 V nominal, 12.4–14.1 V min/max at 5 mA - defines regulated output voltage window under standard test condition |
| Power Dissipation (PD) | 200 mW at TA = 25 °C - limits continuous power handling on FR4 board with recommended pad layout |
| Zener Impedance (ZZT) | ≤30 Ω at IZT = 5 mA - determines regulation stiffness and output voltage variation under load changes |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 8.0 V - ensures minimal parasitic current in standby or high-impedance bias networks |
| Thermal Resistance (RθJA) | 625 K/W - quantifies junction-to-ambient temperature rise per watt dissipated on standard FR4 layout |
| Operating Temperature | –65 to +125 °C - supports industrial and automotive under-hood environments without derating |
| Temperature Coefficient | +7.0 to +11.0 mV/°C at 5 mA - enables compensation design for ambient-induced voltage drift |
Pinout & Package
Package: SOT-323 - ultra-small plastic surface-mount case (2.0 × 1.25 × 0.9 mm), lead-free matte tin plating, UL 94V-0 flammability rating, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal / cathode reference ground path | Connected to lower-potential node in reverse-biased Zener configuration; polarity must match schematic symbol orientation |
| Cathode (Pin 2) | Zener breakdown terminal / regulated output node | Connected to higher-potential supply rail; voltage at this pin clamps to VZ when reverse current exceeds knee threshold |
| Case / Heat Slug (Pin 3) | Non-electrical mechanical tie | Internally connected to cathode in SOT-323 Zener variants - electrically identical to Pin 2; not isolated |
Key Features
| Feature | Design Value |
|---|---|
| Planar die construction | Ensures tight parametric distribution and repeatable breakdown characteristics across production lots |
| Green molding compound | Halogen-free, antimony-free encapsulation compliant with environmental directives and solder reflow safety |
| Ultra-small SOT-323 footprint | Enables placement in high-density portable electronics where board area is constrained below 2.5 mm² |
| Lead-free / RoHS-compliant plating | Matte tin finish over Alloy 42 leadframe meets JEDEC J-STD-020D reflow profile requirements |

FAQ
What is the maximum reverse current at 8.0 V for BZX84C13W-7-F?
The maximum reverse leakage current is 0.1 µA at VR = 8.0 V and TA = 25 °C, as specified in the Electrical Characteristics table. This low leakage ensures minimal loading on high-impedance bias nodes and preserves accuracy in precision reference circuits.
Is BZX84C13W-7-F compatible with lead-free reflow profiles?
Yes - it features matte tin plating over Alloy 42 leadframe and complies with JEDEC J-STD-020D Level 1 moisture sensitivity. Its construction supports standard Pb-free reflow profiles up to 260 °C peak temperature without delamination or parametric shift.
Does the SOT-323 package have an exposed thermal pad?
No - the SOT-323 package for BZX84C13W-7-F has no exposed thermal pad. Thermal dissipation relies solely on conduction through the two signal leads and case body to the PCB copper, with RθJA = 625 K/W measured on FR4 with recommended pad layout.
Can BZX84C13W-7-F be used in series for higher voltage references?
Yes - multiple units can be stacked in series to achieve higher reference voltages, provided current limiting resistors are sized to maintain ≥5 mA per device and total power dissipation remains within derated limits per the power derating curve (Fig. 1).
