Product details
Overview
SZBZX84C62LT1G from onsemi is a 62 V ±5% tolerance Zener diode in SOT-23 package, rated for 250 mW power dissipation on FR-5 board, with 215 Ω dynamic impedance at 5 mA test current and 0.05 μA reverse leakage at 43.4 V. It provides precision voltage regulation in space-constrained power rail protection circuits.
For engineers reviewing the SZBZX84C62LT1G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), thermal coefficient (+43.4 mV/°C), low leakage (<0.05 μA), and AEC-Q101 qualification for automotive use.
Technical Context
This device operates as a two-terminal voltage reference using controlled avalanche breakdown. Its nominal 62 V Zener voltage is specified at 5 mA test current (IZT), with dynamic impedance measured at 215 Ω under same conditions. Temperature coefficient is +43.4 mV/°C, indicating positive drift above 6 V threshold.
The SOT-23 package features anode (Pin 1), no connection (Pin 2), and cathode (Pin 3) configuration. It supports operation across −65°C to +150°C junction temperature range and delivers 120 pF capacitance at 0 V bias and 1 MHz frequency.
Key Specifications

|---|---|
| Zener Voltage | 62 V nominal, 58–66 V range at 5 mA - defines regulated output voltage under standard test conditions |
| Power Dissipation | 250 mW on FR-5 board - sets maximum continuous power handling before thermal derating begins |
| Zener Impedance | 215 Ω at 5 mA - determines voltage regulation stability under varying load currents |
| Reverse Leakage | 0.05 μA at 43.4 V - ensures minimal standby current in high-impedance bias networks |
| Temperature Coefficient | +43.4 mV/°C at 5 mA - quantifies voltage drift per degree Celsius rise in ambient temperature |
| Capacitance | 35 pF at 0 V, 1 MHz - impacts high-frequency noise filtering and signal integrity in bypass applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84C62LT1G | Same electrical specs but lacks SZ-prefix AEC-Q101 qualification and automotive PPAP capability | Approved for commercial-grade consumer electronics only; not suitable for automotive production | Select when cost sensitivity outweighs automotive compliance requirements |
| SZBZX84C62LT3G | Identical electrical and mechanical specs; differs only in tape-and-reel packaging (10,000 pcs vs. 3,000 pcs) | No functional difference; used where high-volume automated placement requires larger reels | Select for large-batch manufacturing with compatible pick-and-place equipment |
Compared with SZBZX84C62LT1G, BZX84C62LT1G offers identical regulation performance but omits automotive qualification, while SZBZX84C62LT3G provides identical functionality in higher-density packaging - enabling trade-offs between compliance assurance and production logistics.
