Product details
Overview
HZU8.2B1TRF-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage stabilization in low-power analog and power-supply feedback circuits, with a nominal Zener voltage of 8.2 V (min 8.56 V, max 8.93 V at 5 mA), dynamic resistance of 30 Ω, and 200 mW power dissipation in an ultra-small URP surface-mount package.
For engineers reviewing the HZU8.2B1TRF-E datasheet, HZU8.2B1TRF-E pinout, HZU8.2B1TRF-E application, or HZU8.2B1TRF-E equivalent, key selection criteria include Zener voltage tolerance (±4.3% at 5 mA), low dynamic impedance for stable regulation under varying load, thermal stability up to 150°C junction temperature, and compatibility with automated SMT assembly due to tape-and-reel packaging (3,000 pcs/reel).
Technical Context
The HZU8.2B1TRF-E operates as a two-terminal shunt regulator, maintaining a stable reference voltage across its cathode-anode terminals when reverse-biased above its breakdown threshold. Its planar silicon construction ensures consistent Zener characteristics and low leakage current (≤2 μA at VR = 5.0 V).
It is characterized at 25°C with 5 mA test current and pulse-tested (PW = 40 ms) to avoid self-heating effects. The device exhibits a negative Zener voltage temperature coefficient near 0 mV/°C (per Fig.2), enabling minimal drift in mid-voltage-range applications such as sensor biasing and ADC reference conditioning.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2LT1G | 8.2 V nominal, ±5% tolerance (vs. HZU8.2B1TRF-E's ±4.3%), 150 mW Pd, SOT-23 package (larger than URP) | Higher power derating required above 70°C ambient; less suitable for ultra-dense layouts | Select when legacy SOT-23 footprint compatibility is mandatory and tighter voltage tolerance is non-critical |
| MMSZ5236BS-TP | 8.2 V nominal, ±5% tolerance, 350 mW Pd, SOD-123 package (2.7 × 1.6 mm vs. URP's 1.55 × 0.8 mm) | Higher power handling but 3.4× larger footprint; higher thermal mass slows transient response | Select when higher surge energy absorption is needed and board area permits larger package |
Compared with BZX84-C8V2LT1G and MMSZ5236BS-TP, the HZU8.2B1TRF-E offers the smallest footprint, tightest voltage grading, and lowest dynamic impedance in its class-making it optimal for miniaturized, high-accuracy voltage reference and clamping roles where space and regulation stability are primary constraints.

FAQ
What is the Zener voltage tolerance of HZU8.2B1TRF-E at 5 mA test current?
The HZU8.2B1TRF-E has a Zener voltage range of 8.56 V to 8.93 V at IZ = 5 mA, corresponding to a ±4.3% tolerance about the nominal 8.2 V rating. This B1-grade specification is tighter than standard B or B2 grades in the same series and is verified per R07DS0423EJ1000 Rev.10.00 test conditions.
Does HZU8.2B1TRF-E support automated optical inspection (AOI) during SMT assembly?
Yes, the HZU8.2B1TRF-E features a visible cathode mark on its top surface per the URP package drawing, enabling reliable AOI detection and orientation verification. Its standardized laser marking ('8•2' code) and consistent URP footprint further ensure compatibility with high-speed placement and inspection systems.
What is the maximum reverse leakage current for HZU8.2B1TRF-E at 5.0 V?
The maximum reverse leakage current (IR) for HZU8.2B1TRF-E is 2 μA at VR = 5.0 V and Ta = 25°C, as specified in the Electrical Characteristics table on page 3 of the datasheet. This low leakage supports energy-efficient operation in always-on sensor and battery-backed circuits.
Can HZU8.2B1TRF-E be used in automotive under-hood applications?
The HZU8.2B1TRF-E supports junction temperatures up to +150°C and storage temperatures from –55°C to +150°C, meeting requirements for many under-hood locations. However, Renesas classifies this part as "Standard" quality grade-not "High Quality"-so it must be validated per customer-specific AEC-Q101 stress testing before deployment in automotive safety-critical subsystems.
What is the thermal derating behavior of HZU8.2B1TRF-E above 25°C ambient?
Per Figure 3 in the datasheet, the HZU8.2B1TRF-E's power dissipation linearly derates from 200 mW at 25°C to zero at approximately 150°C ambient. At 70°C, allowable Pd drops to ~130 mW; at 100°C, it falls to ~80 mW. Designers must apply this curve when sizing series resistors or estimating thermal rise in enclosed enclosures.
