Product details
Overview
HZU13B2JTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for hard-knee, low-noise voltage reference applications, with nominal Zener voltage 13 V (VZ = 12.4–13.6 V at IZ = 0.5 mA), dynamic resistance ZZT = 380 Ω (typ.), and ultra-low noise voltage - approximately 1/3 to 1/10 that of standard HZU series diodes. It operates in surface-mount URP (Ultra small Resin Package) and is used in precision analog front-ends and low-drift reference circuits.
For engineers reviewing the HZU13B2JTRF-E datasheet, HZU13B2JTRF-E pinout, HZU13B2JTRF-E application, or HZU13B2JTRF-E equivalent, key selection criteria include its hard-knee VZ-IZ linearity (1 nA–1 mA), reduced temperature coefficient (≈−1.5 mV/°C), and suitability for low-noise biasing in instrumentation amplifiers and ADC reference buffers.
Technical Context
The HZU13B2JTRF-E implements a hard-knee Zener breakdown characteristic with semi-logarithmic linear VZ-IZ response across 1 nA to 1 mA, enabling stable reference operation at microampere-level currents. Its epitaxial planar structure ensures reproducible breakdown voltage and low leakage.
It exhibits a Zener voltage temperature coefficient of −1.5 mV/°C (typ.) - approximately half that of legacy HZU-series diodes - and maintains low dynamic impedance (ZZT = 380 Ω typ. at IZT = 0.5 mA), supporting high PSRR in regulated reference designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.4–13.6 V at IZ = 0.5 mA - defines stable reference point for precision biasing |
| Dynamic Resistance ZZT | 380 Ω (typ.) at IZT = 0.5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current IR | ≤100 nA at VR = 10.5 V - ensures minimal leakage-induced error in high-impedance nodes |
| Temperature Coefficient γZ | −1.5 mV/°C (typ.) - enables <10 ppm/°C drift in 13 V reference designs |
| Power Dissipation Pd | 150 mW (at Ta = 25°C) - sets maximum continuous DC bias current limit (~11.5 mA at 13 V) |
| Junction Temperature Tj | 150°C - supports operation in industrial ambient environments up to +105°C with derating |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | VZ = 12 V (±5%), ZZT = 9 Ω (at 21 mA), higher noise, larger DO-41 package | Higher power handling but unsuitable for low-current or space-constrained designs | Select only if >20 mA bias current and through-hole mounting are acceptable |
| BZX84-C13 | VZ = 13 V (±5%), ZZT = 30 Ω (at 5 mA), SOT-23 package, no hard-knee linearity spec | Lacks documented 1 nA–1 mA linearity and low-noise optimization | Acceptable for general-purpose regulation but not for precision analog reference use cases |
Compared with 1N4742A and BZX84-C13, the HZU13B2JTRF-E delivers superior low-current linearity, lower noise, and tighter thermal drift - making it uniquely suited for high-resolution measurement systems where reference integrity dominates system accuracy.

FAQ
What is the nominal Zener voltage of the HZU13B2JTRF-E?
The HZU13B2JTRF-E has a nominal Zener voltage of 13 V, with a specified range of 12.4 V to 13.6 V measured at IZ = 0.5 mA per the REJ03G1216-0500 datasheet. This tight tolerance supports accurate voltage referencing in precision analog circuits without external trimming.
Does the HZU13B2JTRF-E support operation at very low bias currents?
Yes, the HZU13B2JTRF-E exhibits semi-logarithmic linear VZ-IZ characteristics from IZ = 1 nA to 1 mA, enabling stable reference behavior even at nanoampere-level bias currents - a key differentiator from conventional Zener diodes and critical for ultra-low-power sensor interfaces.
What is the temperature coefficient of the HZU13B2JTRF-E?
The HZU13B2JTRF-E has a typical temperature coefficient of −1.5 mV/°C, approximately half that of the standard HZU series. This value is confirmed in Figure 2 of the REJ03G1216-0500 datasheet and directly translates to <±0.012% drift per °C around 13 V, supporting high-stability references.
Is the HZU13B2JTRF-E RoHS-compliant and lead-free?
Yes, the HZU13B2JTRF-E is RoHS-compliant and lead-free, consistent with Renesas Electronics' environmental policies and the EU RoHS Directive. The URP package uses lead-free solder-compatible terminations and conforms to JESD22-A112 moisture sensitivity level 1 (MSL-1).
What package type does the HZU13B2JTRF-E use, and what are its dimensions?
The HZU13B2JTRF-E uses the Ultra small Resin Package (URP), also known as SC-76A, with JEITA code PTSP0002ZA-A. Its dimensions are 1.55 mm (min) × 0.80 mm (min), 1.70 mm (nom) × 0.90 mm (nom), and 1.85 mm (max) × 1.05 mm (max), making it suitable for high-density surface-mount PCB layouts.
