Product details
Overview
BZX84C2V4S from Diodes Incorporated is a dual 200 mW surface-mount Zener diode in SOT-363 package, rated for 2.4 V nominal Zener voltage (2.2–2.6 V range at 5 mA), with 100 Ω max Zener impedance at test current and −3.5 to 0 mV/°C temperature coefficient. It provides precision voltage reference and overvoltage clamping in compact power management circuits.
For engineers reviewing the BZX84C2V4S datasheet, BZX84C2V4S pinout, BZX84C2V4S application, or BZX84C2V4S equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (625 °C/W), reverse leakage (<50 µA at 1.0 V), low-capacitance clamping behavior, and RoHS-compliant lead-free construction for space-constrained PCBs.
Technical Context
This dual-Zener device integrates two independent 2.4 V Zener junctions in a single SOT-363 package, enabling bidirectional voltage regulation or symmetrical clamping without external pairing. Its planar die construction ensures stable breakdown characteristics across −65 °C to +150 °C operating range.
The device operates with 5 mA test current (IZT), delivers 100 Ω dynamic impedance (ZZT) at 1 kHz, and exhibits ultra-low reverse leakage (≤50 µA at VR = 1.0 V), making it suitable for low-power biasing and signal-level protection where thermal drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Nom/Min/Max) | 2.4 V / 2.2 V / 2.6 V at 5 mA - defines tight regulation window for reference stability |

| Zener Impedance | 100 Ω max at 5 mA, 1 kHz - ensures minimal voltage shift under load variation |
| Reverse Leakage Current | ≤50 µA at 1.0 V - enables low-quiescent-current bias networks |
| Temp. Coefficient | −3.5 to 0 mV/°C - supports predictable drift compensation in temperature-sensitive references |
| Thermal Resistance | 625 °C/W - requires careful pad layout per AP02001 for safe derating above 25 °C |
| Package | SOT-363 - 6-pin ultra-small outline with dual anode-cathode pairs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS | Single 2.4 V Zener, SOT-323, 350 mW rating, 25 Ω ZZT | Higher power but no dual-junction capability; requires two devices for bidirectional use | Select when higher pulse energy handling is needed and board space allows discrete placement |
| BZX84C2V4LT1G | Same 2.4 V spec, SOT-23 package, single Zener, 350 mW, 100 Ω ZZT | Lacks dual-channel functionality; incompatible for symmetrical clamping topologies | Choose only for single-rail reference where SOT-23 footprint is preferred and dual operation is unnecessary |
Compared with MMBZ5221BS and BZX84C2V4LT1G, the BZX84C2V4S uniquely delivers dual 2.4 V Zeners in one SOT-363, reducing component count and layout complexity for bidirectional protection or split-bias circuits-critical in miniaturized industrial and automotive modules.

FAQ
What is the maximum reverse voltage this device can withstand before breakdown?
The BZX84C2V4S has a nominal Zener voltage of 2.4 V with a guaranteed breakdown range of 2.2 V to 2.6 V at 5 mA test current. It does not specify a separate "maximum reverse voltage" rating-operation beyond 2.6 V under regulated conditions risks exceeding its 200 mW power limit and thermal derating curve.
Can this part replace a single 2.4 V Zener in a circuit?
Yes, but only one of its two Zener junctions should be used-C1/A1 or C2/A2-with the other junction left unconnected. The unused channel must not be shorted or loaded, as it remains electrically isolated but shares thermal mass and package parasitics.
Is the SOT-363 package compatible with standard reflow profiles?
Yes-the SOT-363 package is qualified for lead-free reflow per J-STD-020D Level 1 moisture sensitivity, supporting peak temperatures up to 260 °C. Diodes Inc. recommends following their AP02007 packaging guide and using recommended pad layout from AP02001 for optimal thermal performance.
How does temperature affect its Zener voltage stability?
Its temperature coefficient ranges from −3.5 to 0 mV/°C at 5 mA, meaning voltage decreases slightly with rising temperature. At 100 °C ambient, the 2.4 V nominal may drop by up to ~0.26 V relative to 25 °C-within the 2.2–2.6 V initial tolerance band, preserving functional margin in most bias applications.
