Product details
Overview
HZM24NB1TL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits, with a nominal zener voltage of 24.5 V to 25.57 V at 5 mA, dynamic resistance of 60 Ω max, power dissipation of 200 mW, and operating junction temperature up to 150°C - deployed in industrial sensor signal conditioning and microcontroller voltage reference rails.
For engineers reviewing the HZM24NB1TL-E datasheet, HZM24NB1TL-E pinout, HZM24NB1TL-E application, or HZM24NB1TL-E equivalent, key selection criteria include zener voltage tolerance (±2.2% at 25°C), low temperature coefficient (≈+0.07 mV/°C near 24 V), MPAK surface-mount package compatibility, and reverse current stability under 2 µA at VR = 19 V.
Technical Context
The HZM24NB1TL-E operates as a two-terminal shunt regulator, maintaining stable output voltage across varying load and input conditions by conducting reverse current above its specified breakdown threshold. Its epitaxial planar construction ensures tight VZ distribution and repeatable rd performance.
It is characterized at 5 mA test current with pulse-width-limited testing (Pw = 40 ms) to minimize self-heating effects, and exhibits a positive temperature coefficient of approximately +0.07 mV/°C in the 24 V range - enabling predictable drift compensation in reference designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 24.5 V min to 25.57 V max at IZ = 5 mA - defines stable regulation window for 24 V reference applications. |
| Dynamic Resistance (rd) | 60 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 power handling before thermal derating applies. |
| Reverse Current (IR) | 2 µA max at VR = 19 V - ensures low leakage in standby or high-impedance bias networks. |
| Junction Temperature (Tj) | 150°C max - supports operation in thermally constrained industrial PCB environments. |
| Storage Temperature | –55°C to +150°C - enables use in extended environmental qualification cycles. |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A), 3-pin surface-mount package with 1.0 mm × 1.3 mm footprint, 0.55 mm terminal pitch, and 0.16 mm typical lead thickness - optimized for high-density automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Electrically isolated terminal; must remain unconnected to avoid parasitic coupling or mechanical stress. |
| 2 | Anode | Connected to lower-potential node; reverse-biased operation requires this pin tied to circuit ground or common reference. |
| 3 | Cathode | Connected to higher-potential node; zener breakdown occurs between Cathode and Anode when VR > VZ. |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B1 voltage tolerance | Tight ±2.2% VZ spread (24.5–25.57 V) enables consistent reference accuracy without post-calibration. |
| Low dynamic resistance | 60 Ω max improves line/load regulation in feedback loops and analog front-ends. |
| MPAK package | 0.55 mm pin pitch and 1.0 mm × 1.3 mm body support fine-pitch routing and thermal relief design on 2-layer PCBs. |
| Controlled temperature coefficient | +0.07 mV/°C near 24 V allows predictable drift modeling for compensated references over –25°C to +85°C. |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller Voltage Reference Rail |

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-C24LT1G | VZ = 22.8–25.2 V (±5%), rd = 80 Ω max, Pd = 300 mW, SOT-23 package | Wider VZ tolerance and higher rd reduce reference precision; larger package increases board area. | Preferred where cost sensitivity outweighs reference accuracy and board space is unconstrained. |
| MMSZ4686T1G | VZ = 23.5–25.5 V (±5%), rd = 90 Ω max, Pd = 500 mW, SOD-123 package | Higher power rating but looser grading and no B1-grade option; lacks MPAK's fine-pitch compatibility. | Selected when thermal margin is critical and layout allows 2.7 mm × 1.6 mm footprint. |
Compared with BZX84-C24LT1G and MMSZ4686T1G, the HZM24NB1TL-E delivers tighter VZ control (±2.2% vs. ±5%), lower dynamic resistance (60 Ω vs. ≥80 Ω), and MPAK packaging for high-density layouts - making it optimal for precision industrial references where calibration overhead and PCB real estate are constrained.

FAQ
What is the exact zener voltage range for HZM24NB1TL-E at 25°C?
The HZM24NB1TL-E has a guaranteed zener voltage range of 24.5 V minimum to 25.57 V maximum when tested at IZ = 5 mA and Ta = 25°C. This corresponds to Grade B1 tolerance (±2.2%) within the HZM-N Series specification. The value is verified per R07DS0358EJ0600 Rev.6.00, page 3.
Does HZM24NB1TL-E have a temperature coefficient, and how does it affect circuit design?
Yes, the HZM24NB1TL-E exhibits a positive temperature coefficient of approximately +0.07 mV/°C near its 24 V operating point, as shown in Figure 2 of the datasheet. This means its zener voltage increases linearly with temperature - a factor that must be included in high-accuracy reference designs, especially those operating across –25°C to +85°C ambient ranges. The HZM24NB1TL-E datasheet provides full γZ vs. VZ characterization.
What is the meaning of the 'B1' suffix in HZM24NB1TL-E?
The 'B1' suffix in HZM24NB1TL-E denotes the zener voltage grade: B1 specifies a tighter tolerance band (24.5–25.57 V) compared to B2 (24.8–26.0 V) and B3 (25.1–26.4 V) grades in the same series. This grading enables selective binning for applications demanding higher initial accuracy without trimming. The marking code for HZM24NB1TL-E is "243" per page 4 of the datasheet.
Can HZM24NB1TL-E be used in place of older HZM24N variants?
Yes, the HZM24NB1TL-E is a direct functional upgrade to earlier HZM24N parts, retaining identical MPAK package, pinout (NC-Anode-Cathode), and absolute maximum ratings. However, it offers improved VZ grading (B1 vs. generic B) and tighter dynamic resistance spec (60 Ω vs. 70 Ω for older revisions). Designers should verify layout compatibility with PLSP0003ZC-A footprint dimensions before migration.
Is HZM24NB1TL-E RoHS compliant and halogen-free?
Yes, HZM24NB1TL-E meets RoHS Directive 2011/65/EU requirements and is halogen-free per Renesas' material declarations. The device carries the "EU RoHS Compliant" marking and conforms to JEDEC J-STD-609A Class 1 for moisture sensitivity. Full compliance documentation is available through Renesas' product change notices and material content reports.
