Product details
Overview
SMBJ60AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), 6.2 A peak pulse current (IPPM), and 96.8 V maximum clamping voltage (VC) - deployed for surge protection of MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive ECUs.
For engineers reviewing the SMBJ60AHE3_A/H datasheet, SMBJ60AHE3_A/H pinout, SMBJ60AHE3_A/H application, or SMBJ60AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and compliance with UL 497B for protector classification.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by overvoltage events exceeding its reverse standoff voltage (60 V). Its silicon avalanche junction responds in <1 ps to transient surges, limiting voltage across protected circuitry to ≤96.8 V at 6.2 A peak pulse current under standardized 10/1000 µs waveform conditions.
Designed for surface-mount assembly on PCBs with minimum 0.2" × 0.2" copper pads per terminal, it delivers 5.0 W steady-state power dissipation at 50 °C ambient and supports 100 A non-repetitive forward surge current (8.3 ms half-sine), meeting J-STD-020 MSL Level 1 reflow requirements (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 66.7 V / 73.7 V at IT = 1 mA - Confirmed breakdown range ensures reliable triggering without premature conduction during normal operation. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage level under 600 W 10/1000 µs surge; determines maximum stress imposed on downstream components. |
| PPPM | 600 W - Peak pulse power handling capability; validates robustness against lightning-induced or inductive-switching transients. |
| IFSM | 100 A - Single half-sine surge rating (8.3 ms); supports protection of high-current power rails and motor drivers. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive and industrial environments with elevated ambient temps. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs required PCB copper area and airflow for thermal management. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VREV > VBR; polarity must be observed for unidirectional operation. |
| Anode | Reference/ground return | Typically tied to system ground or low-impedance return path; completes clamping loop during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics; supports extended temperature and reliability requirements. |
| 600 W peak pulse power (10/1000 µs) | Enables suppression of high-energy transients from load dump, relay switching, or ESD coupling without degradation. |
| Glass passivated chip junction | Improves long-term stability and moisture resistance versus epoxy-passivated alternatives; critical for industrial field longevity. |
| MSL Level 1 (260 °C peak) | Permits standard lead-free reflow without preconditioning; eliminates manufacturing delays and moisture sensitivity handling. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), enhancing protection fidelity for sensitive logic inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60AHM3_A/H | Halogen-free variant with identical electrical specs and AEC-Q101 qualification; same SMB package and pinout. | No functional difference; selected where halogen-free compliance is mandated by OEM environmental policies. | Direct drop-in replacement when RoHS + halogen-free material compliance is required. |

FAQ
What is the maximum clamping voltage of SMBJ60AHE3_A/H under a 10/1000 µs surge?
The SMBJ60AHE3_A/H has a maximum clamping voltage (VC) of 96.8 V at 6.2 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ60AHE3_A/H maintains this clamping performance across its full operating temperature range (−55 to +150 °C), ensuring consistent protection behavior in automotive and industrial deployments.
Is SMBJ60AHE3_A/H qualified for automotive applications?
Yes, SMBJ60AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392 (Revision 09-Jan-2024). This qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - validating suitability for under-hood and body-control module applications. The SMBJ60AHE3_A/H meets UL 497B protector classification and supports automotive-grade traceability and lot control.
What is the standoff voltage and breakdown range for SMBJ60AHE3_A/H?
The SMBJ60AHE3_A/H has a reverse standoff voltage (VWM) of 60 V and a breakdown voltage (VBR) range of 66.7 V to 73.7 V at test current IT = 1 mA. This 6.7 V margin between VWM and minimum VBR ensures stable non-conduction during normal operation while guaranteeing activation before damaging overvoltages occur. The SMBJ60AHE3_A/H datasheet specifies these values under TA = 25 °C, with temperature coefficient of VBR at +0.105 %/°C.
Does SMBJ60AHE3_A/H support lead-free reflow assembly?
Yes, SMBJ60AHE3_A/H meets J-STD-020 Moisture Sensitivity Level 1 with a maximum peak reflow temperature of 260 °C, making it compatible with standard lead-free soldering processes without preconditioning. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability, and the molding compound satisfies UL 94 V-0 flammability requirements. The SMBJ60AHE3_A/H is rated for unlimited floor life under dry pack conditions per J-STD-033.
How does SMBJ60AHE3_A/H differ from bidirectional variants like SMBJ60CA?
SMBJ60AHE3_A/H is unidirectional, with cathode marking and conduction only in reverse bias - ideal for DC power line protection. In contrast, SMBJ60CA is bidirectional, symmetrical in both polarities, and used for AC signal or data line protection. The SMBJ60AHE3_A/H has no marking on the anode side and requires correct orientation during placement, whereas SMBJ60CA lacks polarity markings entirely. Electrical parameters such as VBR and VC are specified identically in both directions for the CA variant, but not applicable to the unidirectional SMBJ60AHE3_A/H.
