Product details
Overview
HZM2.4NBTR-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for voltage stabilization in low-power analog and digital circuits, with a nominal zener voltage of 2.4 V (min 2.30 V, max 2.60 V at 5 mA), 200 mW power dissipation, and MPAK surface-mount package. It serves as a precision reference in power supply feedback loops, sensor biasing, and overvoltage protection circuits.
For engineers reviewing the HZM2.4NBTR-E datasheet, HZM2.4NBTR-E pinout, HZM2.4NBTR-E application, or HZM2.4NBTR-E equivalent, key selection criteria include its tight zener voltage tolerance (±0.15 V), low dynamic resistance (100 Ω max at 5 mA), temperature coefficient behavior near zero crossing (~0 mV/°C at ~2.4 V), and suitability for high-density PCB layouts requiring SC-59A-compatible footprint.
Technical Context
This device operates as a two-terminal voltage reference using controlled reverse-bias breakdown in a silicon epitaxial planar junction. Its zener voltage is specified at 5 mA test current with pulse testing (Pw = 40 ms) to limit self-heating, and it exhibits a near-zero temperature coefficient around 2.4 V - confirmed by Fig.2 in the datasheet.
The MPAK package (JEITA code PLSP0003ZC-A, Renesas code MPAK(D)) enables automated high-speed placement and supports thermal dissipation up to 200 mW at 25°C ambient, derating linearly per Fig.3. Pin configuration is fixed: Terminal 1 = NC, Terminal 2 = Anode, Terminal 3 = Cathode - verified from "Pin Arrangement" diagram on Page 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.30–2.60 V at IZ = 5 mA - defines stable regulation range for low-voltage reference applications |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous power handling before thermal derating applies |
| Dynamic Resistance (rd) | ≤100 Ω at IZ = 5 mA - indicates low output impedance critical for ripple rejection in reference circuits |
| Reverse Current (IR) | ≤120 µA at VR = 1.0 V - ensures minimal leakage below breakdown, preserving accuracy in low-current bias networks |
| Junction Temperature (Tj) | 150°C maximum - defines upper thermal limit for reliable long-term operation under load |
| Temperature Coefficient (γZ) | ≈0 mV/°C near 2.4 V - enables stable reference performance across industrial temperature range without external compensation |
Pinout & Package
Package: MPAK (SC-59A compatible), JEITA code PLSP0003ZC-A, dimensions 2.7 × 1.35 × 0.95 mm (L × W × H), mass 0.011 g, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Electrically isolated terminal - must remain unconnected on PCB; no internal bond wire or junction |
| 2 | Anode | Forward-bias terminal; connected to lower-potential node in reverse-bias regulation configuration |
| 3 | Cathode | Zener breakdown terminal; connected to higher-potential node and output reference point |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B zener voltage tolerance | ±0.15 V at 2.4 V - enables predictable regulation without post-manufacturing trimming |
| MPAK surface-mount package | 0.95 mm profile with 2.7 mm length - supports ultra-compact layout and reflow-compatible assembly |
| Pulse-tested electrical specs | Tested with 40 ms pulses - ensures parameter stability under transient conditions typical in power supply startup |
| Low leakage at sub-zener voltage | <120 µA at 1.0 V reverse bias - minimizes error current in high-impedance reference divider networks |
| Zero-crossing temperature coefficient | γZ ≈ 0 mV/°C near 2.4 V - eliminates need for external tempco compensation in precision references |

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-C2V4LT1G | 2.4 V ±5% (0.12 V tolerance), SOT-23 package, 350 mW Pd, rd = 100 Ω typical | Higher power rating but wider VZ tolerance; less stable over temperature (γZ = +2.5 mV/°C) | Select when higher surge power capability is needed and tighter tempco is not required. |
| MMSZ4676T1G | 2.4 V ±5%, SOD-123 package, 500 mW Pd, rd = 120 Ω max, Tj = 150°C | Larger footprint (SOD-123 vs MPAK), higher leakage (≤50 µA at 1 V), no zero-tempco point | Choose for cost-sensitive designs where board space is less constrained and thermal margin is prioritized. |
Compared with BZX84-C2V4LT1G and MMSZ4676T1G, HZM2.4NBTR-E offers superior voltage stability near room temperature due to its engineered zero-tempco point at 2.4 V, tighter absolute VZ spread (±0.15 V vs ±0.12 V), and smallest package height (0.95 mm), making it optimal for space- and precision-critical applications.

FAQ
What is the exact zener voltage range for HZM2.4NBTR-E at 5 mA?
The HZM2.4NBTR-E has a guaranteed zener voltage range of 2.30 V to 2.60 V when tested at IZ = 5 mA and Ta = 25°C, per the Electrical Characteristics table on Page 2 of the R07DS0358EJ0600 datasheet. This ±0.15 V tolerance reflects Grade-B specification and is validated using 40 ms pulse testing to avoid self-heating effects. The HZM2.4NBTR-E achieves this precision through epitaxial planar junction processing.
Is HZM2.4NBTR-E pin-compatible with standard SOT-23 Zener diodes?
No, HZM2.4NBTR-E uses the MPAK (SC-59A compatible) package with a unique 3-pin arrangement: Pin 1 = NC, Pin 2 = Anode, Pin 3 = Cathode. Standard SOT-23 Zeners use 3-pin configurations with Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = NC - making direct PCB replacement impossible without layout revision. The HZM2.4NBTR-E footprint differs in pad pitch, body size (2.7 × 1.35 mm), and terminal assignment.
Does HZM2.4NBTR-E have a specified temperature coefficient, and how does it affect performance?
Yes, the HZM2.4NBTR-E exhibits a temperature coefficient (γZ) near 0 mV/°C at 2.4 V, as shown in Fig.2 on Page 5 of the datasheet. This zero-crossing behavior minimizes drift over the industrial temperature range (–25°C to +85°C), making the HZM2.4NBTR-E especially suitable for precision reference applications where active temperature compensation would otherwise be required.
What is the maximum reverse leakage current for HZM2.4NBTR-E below its zener voltage?
The HZM2.4NBTR-E specifies a maximum reverse leakage current (IR) of 120 µA at VR = 1.0 V and Ta = 25°C. This low leakage ensures minimal error current in high-impedance voltage divider networks used with the HZM2.4NBTR-E, preserving accuracy in battery-powered or low-quiescent-current designs where every microamp matters.
Can HZM2.4NBTR-E be used in place of a 2.5 V reference IC in simple applications?
The HZM2.4NBTR-E provides a passive 2.4 V reference with ±0.15 V tolerance and near-zero tempco, making it viable for non-critical applications where 100 mV lower voltage is acceptable and output current demand is ≤5 mA. However, unlike active reference ICs, the HZM2.4NBTR-E lacks buffered output, line/load regulation, or initial accuracy better than ±6.25%. Use HZM2.4NBTR-E only where system-level calibration accommodates its inherent tolerance and dynamic impedance.
