Product details

Overview

BZX84C4V7TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 4.7 V (±0.3 V) Zener elements in a single SOT-363 package, rated for 200 mW total power dissipation, 80 Ω dynamic impedance at 5 mA test current, and operating across –65 °C to +150 °C. It serves as precision voltage reference and overvoltage clamp in compact DC power rail monitoring circuits.

For engineers reviewing the BZX84C4V7TS-7-F datasheet, BZX84C4V7TS-7-F pinout, BZX84C4V7TS-7-F application, or BZX84C4V7TS-7-F equivalent, key selection criteria include nominal Zener voltage tolerance (4.4–5.0 V), low reverse leakage (≤3.0 µA at 2.0 V), temperature coefficient (–3.5 to +0.2 mV/°C), and SOT-363 footprint compatibility with high-density PCB layouts.

Technical Context

This device integrates three independent Zener diodes sharing no internal connection-each functions as a standalone 4.7 V voltage reference or transient suppressor. All elements are characterized at I_ZT = 5 mA with guaranteed Zener voltage range (4.4–5.0 V) and maximum Zener impedance of 80 Ω at 1 kHz.

Thermal performance is defined by R_θJA = 625 °C/W on FR4 board with recommended pad layout, enabling stable regulation under pulsed loads up to 200 mW. The device exhibits a negative-to-slightly-positive temperature coefficient (–3.5 to +0.2 mV/°C), supporting predictable drift behavior in ambient-varying environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	4.7 V nominal, 4.4–5.0 V min/max at I_ZT = 5 mA - ensures tight regulation window for 5 V rail clamping
Power Dissipation (P_D)	200 mW - supports continuous operation in low-power sensing and bias networks
Zener Impedance (Z_ZT)	80 Ω max at 1 kHz - maintains stable output under small-signal AC ripple conditions
Reverse Leakage (I_R)	≤3.0 µA at V_R = 2.0 V - minimizes quiescent current draw in battery-backed circuits
Temp Coefficient (α_VZ)	–3.5 to +0.2 mV/°C - enables predictable voltage shift across industrial temperature range
Package	SOT-363 - 3-channel ultra-small footprint (2.2 × 1.35 × 0.9 mm) for space-constrained designs

Pinout & Package

SOT-363 package: 6-pin, dual-row surface-mount outline with three isolated anode-cathode pairs. Pin 1 (A1), Pin 2 (C1), Pin 3 (A2), Pin 4 (C2), Pin 5 (A3), Pin 6 (C3); A = anode, C = cathode per diode element.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode of Diode 1	Connects to lower-potential node when clamping or referencing 4.7 V
C1	Cathode of Diode 1	Connects to regulated 4.7 V node or protection target point
A2	Anode of Diode 2	Independent anode path-no internal coupling to Diode 1 or 3
C2	Cathode of Diode 2	Enables parallel or separate 4.7 V reference paths on same substrate
A3	Anode of Diode 3	Third isolated anode for multi-rail or redundancy use cases
C3	Cathode of Diode 3	Supports triple-rail monitoring without cross-talk or shared thermal path

Key Features

Feature	Design Value
Triple isolated Zener elements	Three independent 4.7 V references in one SOT-363 - reduces component count and layout area vs. discrete diodes

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode array applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBZ5225BS-7-F	Single 3.6 V Zener in SOT-363; 500 mW rating; higher leakage (5 µA @ 1 V)	Not triple-element; unsuitable for multi-rail clamping	Select only if single-channel 3.6 V reference suffices and higher power margin is needed
BZX84C4V7LT1G	Single 4.7 V Zener in SOT-23; 350 mW rating; identical V_Z tolerance but no channel isolation	Lacks integrated triple-diode architecture; requires three placements	Choose when board area allows discrete placement and thermal independence is not required

Compared with BZX84C4V7TS-7-F, MMBZ5225BS-7-F offers higher power but lacks multi-channel integration, while BZX84C4V7LT1G matches voltage spec but increases assembly cost and layout area due to requiring three separate devices.

FAQ

What is the maximum reverse voltage this device can withstand before breakdown?

The BZX84C4V7TS-7-F has a nominal Zener voltage of 4.7 V with guaranteed breakdown between 4.4 V and 5.0 V at 5 mA test current. Its reverse breakdown is sharply defined within this range; operation below 4.4 V results in negligible conduction (<3.0 µA at 2.0 V), making it unsuitable as a general-purpose rectifier.

Can all three Zener elements be used simultaneously without thermal interaction?

Yes - the three Zener elements are electrically isolated and share only the common SOT-363 plastic mold body. Thermal coupling is minimal due to low 200 mW total dissipation and 625 °C/W junction-to-ambient resistance; simultaneous full-power operation across all channels remains within safe operating limits per Diodes Inc. derating curve.

Is this device suitable for use in automotive applications?

Yes - it is qualified for operation from –65 °C to +150 °C and manufactured with halogen-free, RoHS-compliant materials. Diodes Incorporated specifies this series for industrial and automotive-grade use, and its SOT-363 package meets J-STD-020D Level 1 moisture sensitivity requirements for reflow soldering in automotive production lines.

How does the temperature coefficient affect long-term voltage stability?

The temperature coefficient ranges from –3.5 to +0.2 mV/°C at 5 mA, meaning output voltage may drift up to ±0.35 V over a 100 °C span. For applications demanding <±0.1 V stability, external compensation or tighter-tolerance references should be considered - this part is optimized for cost-sensitive, moderate-accuracy clamping rather than metrology-grade referencing.
