Product details
Overview
SMB10J5.0AHE3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 1000 W peak pulse power (10/1000 µs), 108.7 V clamping voltage at 108.7 A peak surge current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMB10J5.0AHE3_A/I datasheet, SMB10J5.0AHE3_A/I pinout, SMB10J5.0AHE3_A/I application, or SMB10J5.0AHE3_A/I equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating above 25 °C, compliance with automotive reliability standards, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a shunt-clamping device that remains high-impedance below VWM (5.0 V) and rapidly transitions to low-impedance conduction once VBR (6.4–7.07 V) is exceeded. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and repeatable breakdown behavior across temperature.
Designed for transient suppression per IEC 61000-4-5 and ANSI/IEEE C62.35, it delivers 1000 W peak pulse power with low incremental surge resistance and fast response time (<1 ns), enabling robust protection of downstream MOSFETs, ICs, and sensor interfaces against inductive switching spikes and ESD events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Same SMB package, identical VWM/VBR/VC specs, but commercial-grade (non-AEC-Q101) and RoHS-compliant only | Lacks automotive qualification; suitable for consumer/industrial designs without AEC requirements | Select when cost sensitivity outweighs automotive qualification needs and lifecycle assurance is less critical |
| 1.5SMC5.0A | Higher-power SMC package (1500 W), same 5.0 V VWM, but larger footprint (0.265" × 0.235") and higher RθJA (50 °C/W vs. 72 °C/W) | Better energy handling but requires more board space; thermal design differs due to package geometry | Choose when system-level surge threat exceeds 1000 W or when existing layout accommodates SMC footprint |
Compared with SMBJ5.0A-E3/52, SMB10J5.0AHE3_A/I adds AEC-Q101 qualification and tighter process control for automotive use; versus 1.5SMC5.0A, it trades 500 W peak power for smaller SMB footprint and lower assembly cost in space-constrained modules.

FAQ
What is the clamping voltage of SMB10J5.0AHE3_A/I at its rated peak pulse current?
The SMB10J5.0AHE3_A/I has a maximum clamping voltage (VC) of 9.2 V when subjected to its peak pulse current (IPPM) of 108.7 A under the standard 10/1000 µs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on the protected circuit during surge events, making it critical for verifying compatibility with downstream IC absolute maximum ratings. The SMB10J5.0AHE3_A/I maintains this clamping performance across its qualified operating temperature range.
Is SMB10J5.0AHE3_A/I suitable for bidirectional transient protection?
No, SMB10J5.0AHE3_A/I is a unidirectional TVS diode, intended for DC circuits where polarity is fixed-such as 5 V power rails or signal lines referenced to ground. It conducts only in reverse bias above VBR and blocks forward current beyond VF ≈ 3.5 V at 50 A. For AC or floating-line applications requiring symmetrical clamping, a bidirectional variant like SMB8J5.0CA must be selected instead. The SMB10J5.0AHE3_A/I datasheet explicitly specifies unidirectional polarity and does not characterize bidirectional behavior.
What does the "HE3" suffix indicate in SMB10J5.0AHE3_A/I?
The "HE3" suffix in SMB10J5.0AHE3_A/I denotes RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade variants (e.g., "E3") and halogen-free automotive versions ("HM3"). The "H" signifies automotive qualification, "E3" confirms RoHS compliance, and "_A/I" specifies packaging: "A" is the revision code, and "I" indicates 13-inch tape-and-reel delivery (3200 units per reel). This coding ensures traceability to Vishay's qualified automotive manufacturing flow for the SMB10J5.0AHE3_A/I.
How does SMB10J5.0AHE3_A/I perform thermally during repeated surge events?
SMB10J5.0AHE3_A/I exhibits a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" copper pads per Vishay's recommended layout. Under repetitive surges, junction temperature rise is governed by pulse width, duty cycle, and ambient conditions-derating curves in Figure 2 show >50% power reduction above 25 °C ambient. The SMB10J5.0AHE3_A/I's 150 °C maximum junction temperature allows sustained operation in under-hood environments when PCB layout and airflow meet specification guidelines.
Can SMB10J5.0AHE3_A/I replace older SMBJ5.0A parts in existing designs?
SMB10J5.0AHE3_A/I shares identical electrical specifications (VWM, VBR, VC, PPPM) and SMB (DO-214AA) mechanical dimensions with SMBJ5.0A, enabling direct drop-in replacement in most cases. However, SMB10J5.0AHE3_A/I adds AEC-Q101 qualification and tighter process controls, making it preferable for new automotive designs. Layout changes are unnecessary, but users should verify that the "HE3" suffix meets their qualification and sourcing requirements-especially for PPAP documentation and long-term supply assurance in the SMB10J5.0AHE3_A/I.
