Product details
Overview
BZX84C13-G3-08 from Vishay Semiconductors is a silicon planar Zener diode rated for 13 V nominal Zener voltage (±5 % tolerance), 5 mA test current, 30 Ω dynamic resistance at 5 mA, and 500 mW maximum power dissipation on lead; it serves as a precision voltage reference or overvoltage clamp in low-power analog and digital supply regulation circuits.
For engineers reviewing the BZX84C13-G3-08 datasheet, BZX84C13-G3-08 pinout, BZX84C13-G3-08 application, or BZX84C13-G3-08 equivalent, this part supports stable voltage referencing in space-constrained SOT-23 designs requiring ±5 % tolerance, 150 °C junction temperature rating, and AEC-Q101-compatible ESD robustness (HBM > 8 kV).
Technical Context
This Zener diode operates in reverse breakdown mode with a specified Zener voltage of 12.4–13.65 V at 5 mA test current (IZT1), exhibiting a positive temperature coefficient of +7 to +9 × 10⁻⁴/°C. Its dynamic resistance (ZZ) is 30 Ω at IZT1 and 170 Ω at knee current (IZT2 = 1 mA), ensuring predictable regulation under varying load conditions.
The device uses a single-diode configuration in SOT-23 package, with thermal resistance junction-to-ambient of 420 K/W on FR-4 board and junction-to-lead of 250 K/W. It is rated for operation from –55 °C to +150 °C and storage from –65 °C to +150 °C, supporting industrial and automotive ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.4–13.65 V at 5 mA - defines precise clamping/reference level for 13 V rail stabilization |
| Test Current (IZT) | 5 mA - standard operating point for guaranteed VZ specification and dynamic resistance measurement |
| Dynamic Resistance (ZZ) | 30 Ω at 5 mA - determines output impedance and regulation error under small-signal load variation |
| Power Dissipation (Ptot) | 300 mW on FR-4 board - sets maximum continuous power handling in typical PCB layout |
| Reverse Leakage (IR) | ≤ 0.1 μA at 10.4 V - ensures minimal quiescent current in standby or high-impedance bias networks |
| Temperature Coefficient (αVZ) | +7 to +9 × 10⁻⁴/°C - quantifies VZ drift per degree Celsius, critical for temperature-stable references |
| Junction Temperature (Tj) | 150 °C maximum - defines upper thermal limit for reliable long-term operation |
Pinout & Package
SOT-23 surface-mount plastic package (9.2 mg weight, UL 94 V-0 molding compound, MSL level 1); three-terminal configuration with anode, cathode, and substrate tie (cathode marked by band).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Forward conduction terminal | Connected to lower-potential node in reverse-biased Zener operation; required for proper polarity in clamping or reference circuits |
| 2 (Cathode) | Zener breakdown terminal | Marked with band; connects to higher-potential node; carries regulated voltage output when reverse biased |
| 3 (Emitter / Substrate) | Internal substrate connection | Internally tied to cathode in standard SOT-23 Zener construction; not electrically isolated - functions as second cathode terminal |
Key Features
| Feature | Design Value |
|---|---|
| Silicon planar construction | Ensures tight process control for repeatable Zener voltage distribution and low parameter drift over time |
| ±5 % Zener voltage tolerance ('C' grade) | Meets E24 standard grading; suitable for non-critical voltage references where cost and availability outweigh ultra-tight tolerance needs |
| ESD robustness (HBM > 8 kV) | Enables safe handling and assembly without special static protection in standard manufacturing environments |
| AEC-Q101 qualification available | Supports automotive-grade reliability requirements when ordered with AEC-Q101 suffix (not included in BZX84C13-G3-08 base part number) |
| MSL level 1 moisture sensitivity | Permits unlimited floor life before reflow; eliminates baking requirement for standard SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5243B-7-F | 13 V nominal, ±5 %, 200 mW Ptot, 30 Ω ZZ at 20 mA (not 5 mA) | Lower power rating and different test current shift regulation point; less suitable for low-current reference use | Select BZX84C13-G3-08 for 5 mA–optimized stability and 300 mW FR-4 board rating. |
| 1N4743A | 13 V nominal, ±5 %, DO-35 package (axial lead), 1 W Ptot, 10 Ω ZZ at 25 mA | Through-hole format, higher power, lower ZZ, but incompatible with SMT automation and dense layouts | Choose BZX84C13-G3-08 for automated SMT assembly, space-constrained PCBs, and thermal performance on FR-4. |
Compared with MMBZ5243B-7-F, BZX84C13-G3-08 offers higher board-level power handling (300 mW vs. 200 mW) and tighter test-current alignment for low-current references; versus 1N4743A, it enables miniaturized SMT implementation despite slightly higher dynamic resistance.
