Product details
Overview
BZT52C2V4-13-F from Diodes Incorporated is a surface-mount Zener diode with a nominal zener voltage of 2.4 V, 500 mW power dissipation (at TL = +75°C), and 100 Ω maximum zener impedance at 5 mA test current. It features SOD123 package, cathode band polarity marking, and AEC-Q101 qualification for automotive-grade reliability - used for precision voltage reference and overvoltage protection in low-voltage power rails.
For engineers reviewing the BZT52C2V4-13-F datasheet, BZT52C2V4-13-F pinout, BZT52C2V4-13-F application, or BZT52C2V4-13-F equivalent, key selection criteria include its 2.2–2.6 V zener tolerance, -3.5 mV/°C temperature coefficient, 50 µA max reverse leakage at 1.0 V, 0.9 V forward voltage at 10 mA, and SOD123 thermal resistance profile for PCB-level thermal design.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation across varying load currents, with specified test conditions at 5 mA and thermal derating per Fig. 1. Its planar die construction ensures consistent breakdown characteristics and low leakage performance.
The device exhibits a negative temperature coefficient (-3.5 mV/°C) and is characterized up to 150°C junction temperature, supporting operation in automotive under-hood and industrial control environments where ambient temperatures exceed 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.4 V nominal, 2.2–2.6 V range at 5 mA - defines regulated output voltage tolerance in reference circuits |
| Power Dissipation | 500 mW at lead temperature 75°C - sets maximum continuous power handling with proper PCB copper pad layout |
| Zener Impedance (ZZT) | 100 Ω max at 5 mA - determines regulation stiffness and AC ripple rejection capability |
| Reverse Leakage (IR) | 50 µA max at 1.0 V reverse bias - impacts quiescent current in low-power voltage clamp designs |
| Forward Voltage (VF) | 0.9 V at 10 mA - defines conduction loss when used as ESD clamp or forward-biased protection element |
| Temperature Coefficient | -3.5 mV/°C - enables predictable drift compensation in temperature-sensitive analog references |
| Package | SOD123 - surface-mount footprint compatible with automated pick-and-place and reflow assembly |
Pinout & Package
Two-terminal SOD123 package with cathode band marking on the case. Terminals are anode (unmarked end) and cathode (band-marked end). Matte tin-plated alloy 42 leadframe ensures solderability per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal in forward bias; connected to lower-potential node in Zener regulation | Reference ground or return path for clamped current during overvoltage events |
| Cathode | Negative terminal in forward bias; higher-potential node in Zener regulation | Connected to regulated voltage rail or input node requiring voltage stabilization or transient suppression |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | Zener voltage 2.4 V, but rated at 225 mW (SOT-23); higher ZZT (150 Ω) and wider tolerance (2.2–2.6 V same) | Limited power handling restricts use in sustained clamp scenarios; better suited for low-current biasing | Select when board space is constrained and peak power <225 mW; avoid for automotive under-hood thermal cycling |
| BZX84-C2V4 | Same 2.4 V rating but SOT-23 package, 350 mW PD, higher leakage (100 µA @ 1 V), no AEC-Q101 qualification | Not qualified for automotive use; higher leakage increases error in precision reference designs | Acceptable for commercial-grade consumer electronics where cost and footprint are prioritized over reliability |
Compared with BZT52C2V4-13-F, MMBZ5221BS-7-F offers smaller size but sacrifices thermal robustness and automotive qualification, while BZX84-C2V4 trades qualification and leakage performance for broader distributor availability and lower unit cost.

FAQ
What is the maximum reverse voltage (VR) before significant leakage occurs in BZT52C2V4-13-F?
At 1.0 V reverse bias, the maximum reverse current is 50 µA per the datasheet's Electrical Characteristics table. This value rises to 150 µA at 2.0 V reverse bias, confirming that the device remains well within low-leakage operation up to its rated zener voltage of 2.4 V.
Can BZT52C2V4-13-F be used in place of a 2.5 V Zener diode?
No - its nominal zener voltage is 2.4 V with a guaranteed range of 2.2–2.6 V, making it unsuitable as a direct replacement for a true 2.5 V part like BZT52C2V5. The 0.1 V offset may cause functional errors in precision reference or threshold-detection circuits requiring exact 2.5 V regulation.
Is the SOD123 package of BZT52C2V4-13-F compatible with standard reflow profiles?
Yes - the device is rated for moisture sensitivity Level 1 per J-STD-020 and uses matte tin finish on alloy 42 leads, enabling compatibility with standard Pb-free reflow profiles (peak 260°C, 60-second duration) without pre-bake requirements or solderability degradation.
Does BZT52C2V4-13-F support bidirectional ESD protection?
No - it is a unidirectional Zener diode optimized for reverse-bias regulation and clamping. For bidirectional ESD protection, a dedicated TVS diode such as D3V3M1U2S-7 is required; this part lacks symmetric breakdown characteristics and has no specified positive-going surge rating.
