Product details
Overview
HZU5.6B2TRF-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage stabilization in low-power analog and power-supply reference circuits, with a nominal Zener voltage of 5.6 V (min 5.67 V, max 5.92 V at 5 mA), dynamic resistance of 80 Ω, and power dissipation rating of 200 mW in the ultra-small URP (SC-76A) surface-mount package.
For engineers reviewing the HZU5.6B2TRF-E datasheet, HZU5.6B2TRF-E pinout, HZU5.6B2TRF-E application, or HZU5.6B2TRF-E equivalent, this device serves as a compact, tape-and-reel–ready voltage reference for battery-powered sensors, LDO feedback networks, and overvoltage protection clamping where tight tolerance (±2.8% at 5 mA), low dynamic impedance, and thermal stability are required.
Technical Context
The HZU5.6B2TRF-E operates as a two-terminal, reverse-biased Zener diode optimized for stable breakdown conduction at 5.6 V under 5 mA test current. Its silicon planar construction ensures reproducible Zener characteristics and low temperature coefficient near zero crossing (~0 mV/°C at ~5.6 V, per Fig.2).
It is rated for junction temperatures up to 150°C and storage from –55°C to +150°C, with pulse-tested electrical parameters (40 ms pulse width) to minimize self-heating during characterization. The URP package enables high-density PCB layouts while maintaining thermal performance within derated ambient conditions (see Fig.3).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.67 V to 5.92 V at IZ = 5 mA - defines stable regulation window for reference or clamp operation |
| Dynamic Resistance (rd) | 80 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous DC power handling before thermal derating |
| Reverse Current (IR) | 5 µA max at VR = 2.5 V - specifies leakage level below breakdown, critical for low-power standby accuracy |
| Junction Temperature (Tj) | 150°C max - constrains operating ambient and PCB copper area requirements for thermal management |
| Package | URP (SC-76A), 0.8 mm × 0.8 mm footprint - enables 0201-class board space efficiency with standard SMT reflow compatibility |
Pinout & Package
URP (Ultra Small Resin Package) is a 2-pin surface-mount package conforming to SC-76A outline, with cathode marked by polarity symbol on top surface. Total mass is 0.004 g (typ.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to higher potential in reverse-bias configuration; carries regulated output node in shunt regulator topology |
| 2 | Anode | Connected to lower potential (typically ground or return path); completes current loop during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Taped delivery (TRF) | 3,000 pcs/reel - supports automated SMT placement without manual handling or static risk |
| Ultra-small URP package | 0.8 mm × 0.8 mm footprint - reduces PCB area by >50% vs. SOD-323, enabling miniaturized wearables and IoT nodes |
| Grade B2 tolerance | ±2.8% Zener voltage spread (5.67–5.92 V) - balances cost and precision for non-critical reference applications |
| Pulse-tested parameters | 40 ms test pulse width - eliminates self-heating error during specification measurement, ensuring real-world repeatability |

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 |
|---|---|---|---|
| BZX584-C5V6 | 5.6 V ±5%, 250 mW, SOD-523 package (1.2 × 0.8 mm) | Higher power rating but larger footprint; slightly wider voltage tolerance | Select for higher surge immunity where board space allows |
| MMSZ5232BS-7-F | 5.6 V ±5%, 500 mW, SOD-123 package (3.7 × 1.6 mm) | 3× higher Pd, but 4.6× larger area; suited for higher-current clamping | Select when >200 mW dissipation or higher reliability under surge is required |
Compared with BZX584-C5V6 and MMSZ5232BS-7-F, the HZU5.6B2TRF-E offers the smallest PCB footprint and tightest voltage tolerance in its power class, making it optimal for space-constrained, precision-limited designs where 200 mW suffices.

FAQ
What is the Zener voltage tolerance of HZU5.6B2TRF-E?
The HZU5.6B2TRF-E has a Zener voltage range of 5.67 V to 5.92 V at 5 mA test current, corresponding to Grade B2 tolerance (±2.8% around nominal 5.6 V). This is verified per R07DS0423EJ1000 Rev.10.00, page 2, and reflects tighter control than standard Grade B (±5%) devices. The HZU5.6B2TRF-E achieves this via binning during final test.
Is HZU5.6B2TRF-E suitable for use in automotive applications?
The HZU5.6B2TRF-E is classified as a Standard-grade Renesas product, intended for computers, office equipment, communications, and industrial robots-not automotive safety-critical systems. It meets RoHS and JEDEC moisture sensitivity level (MSL) requirements for general industrial use, but does not carry AEC-Q200 qualification. For automotive applications, consult Renesas' qualified HZU-AEC variants or alternative AEC-Q200 Zener families.
What is the thermal derating behavior of HZU5.6B2TRF-E above 25°C?
Per Fig.3 in the HZU5.6B2TRF-E datasheet (R07DS0423EJ1000), power dissipation linearly derates from 200 mW at 25°C to 0 mW at 150°C ambient. At 85°C, allowable Pd drops to approximately 120 mW. This requires appropriate PCB copper area (≥25 mm² per pad recommended) and avoids enclosure-level ambient exceedance in sealed designs.
Does HZU5.6B2TRF-E have a specified temperature coefficient?
Yes - the HZU5.6B2TRF-E exhibits a near-zero temperature coefficient at its 5.6 V operating point, approximately 0 mV/°C (or ~0.00%/°C), as shown in Fig.2 of the datasheet. This makes it especially suitable for stable reference applications across –20°C to +70°C, unlike lower- or higher-voltage Zeners that show stronger positive or negative drift.
What marking code identifies HZU5.6B2TRF-E on the package?
The laser mark on the HZU5.6B2TRF-E package is "5•6", per page 4 of R07DS0423EJ1000. This distinguishes it from other grades (e.g., HZU5.6B3 is marked "5•6" with different internal binning) and confirms the B2 grade (5.67–5.92 V). The marking appears adjacent to the cathode indicator on the URP top surface.
