Product details
Overview
HZU15B3TRF-E from Renesas Electronics is a silicon planar Zener diode designed for voltage stabilization in low-power analog and digital circuits, featuring a nominal Zener voltage of 14.85–15.52 V at 5 mA test current, 2 mW reverse leakage current at 11.0 V, and 40 Ω dynamic resistance - deployed in compact power supply regulation and reference circuits.
For engineers reviewing the HZU15B3TRF-E datasheet, HZU15B3TRF-E pinout, HZU15B3TRF-E application, or HZU15B3TRF-E equivalent, this page delivers verified electrical specs, URP package dimensions, cathode/anode terminal mapping, thermal derating behavior, and direct alternatives for precision voltage reference design.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage under varying load and input conditions. Its planar junction construction ensures consistent breakdown characteristics and low temperature coefficient (±0.04 %/°C typical near 15 V), validated per JEITA standard SC-76A footprint.
The device is rated for 200 mW power dissipation at 25°C ambient, with linear derating above 25°C (see Fig.3), and supports operation up to 150°C junction temperature. It is not intended for surge suppression or transient clamping - only steady-state voltage regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.85–15.52 V at IZ = 5 mA - defines regulated output voltage tolerance band for reference design |
| Dynamic Resistance (rd) | 40 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Leakage Current (IR) | 2 µA max at VR = 11.0 V - sets minimum bias current requirement for stable regulation |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - limits maximum continuous power before thermal shutdown risk |
| Junction Temperature (Tj) | −55 to +150°C - defines operational envelope for industrial-grade reliability |
| Package | URP (Ultra small Resin Package), JEITA SC-76A - enables 0.8 mm × 1.5 mm surface-mount placement |
| Marking Code | "15·" laser-marked on cathode side - confirms B3 grade and HZU15 series identity |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15LT1G | 15 V nominal, ±5% tolerance (vs. ±3.3%), 500 mW Pd, SOT-23 package (larger than URP) | Higher power handling but less board-area efficient; requires larger pad layout | Preferred when higher surge margin or legacy SOT-23 footprint compatibility is required |
| MMSZ5245B-TP | 15 V nominal, ±5% tolerance, 500 mW Pd, SOD-123 package (1.8 mm × 1.4 mm) | Wider voltage tolerance and larger footprint; slightly higher rd (45 Ω) | Selected where cost sensitivity outweighs size constraints and tighter regulation is not critical |
Compared with BZX84-C15LT1G and MMSZ5245B-TP, the HZU15B3TRF-E offers superior board-area efficiency (0.8 × 1.5 mm), tighter B3-grade voltage tolerance, and optimized thermal performance for space-limited industrial control modules - though at lower absolute power rating.

FAQ
What is the Zener voltage tolerance of HZU15B3TRF-E?
The HZU15B3TRF-E has a Zener voltage range of 14.85 V to 15.52 V at 5 mA test current, corresponding to B3 grade with ±3.3% tolerance. This is confirmed in the Electrical Characteristics table on page 2 of R07DS0423EJ1000 Rev.10.00, and applies strictly to the HZU15B3TRF-E variant - not broader HZU15 family grades.
Does HZU15B3TRF-E support reflow soldering?
Yes, the HZU15B3TRF-E's URP package is qualified for standard lead-free reflow profiles (JEDEC J-STD-020). Its glass epoxy substrate and tin-silver-copper terminations withstand peak temperatures up to 260°C for ≤30 seconds, as validated by Renesas' package reliability testing referenced in the datasheet's Package Dimensions section.
What is the thermal derating behavior of HZU15B3TRF-E?
HZU15B3TRF-E exhibits linear thermal derating above 25°C ambient: power dissipation decreases from 200 mW at 25°C to zero at 150°C, per Fig.3 in R07DS0423EJ1000. The slope is −2.22 mW/°C, calculated from (200 mW)/(150 − 25)°C - critical for designing sustained operation in enclosed enclosures.
Is HZU15B3TRF-E suitable for surge protection?
No, HZU15B3TRF-E is not designed for surge or transient suppression. Its 200 mW power rating and 40 Ω dynamic resistance indicate it is optimized for steady-state voltage regulation only. For surge protection, TVS diodes such as P6SMB15A (600 W peak pulse power) should be used instead of HZU15B3TRF-E.
How is the cathode identified on HZU15B3TRF-E?
The cathode of HZU15B3TRF-E is marked with a visible laser-etched "15·" symbol on the top surface, positioned adjacent to terminal 1 as shown in the Pin Arrangement diagram on page 1 of R07DS0423EJ1000. Terminal 1 is the cathode; terminal 2 is the anode - correct orientation is essential for reverse-bias operation of the HZU15B3TRF-E.
