Product details
Overview
SMBJ60AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features 60 V standoff voltage (VWM), 66.7–73.7 V breakdown range (VBR at 1 mA), 96.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom line cards.
For engineers reviewing the SMBJ60AHE3/5B datasheet, SMBJ60AHE3/5B pinout, SMBJ60AHE3/5B application, or SMBJ60AHE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status (confirmed by HE3 suffix), thermal resistance (RθJA = 100 °C/W), low leakage (<1.0 µA at 60 V), and compliance with UL 497B for protector classification.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream circuitry. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs surges at 0.01% duty cycle. The device is rated for -55 °C to +150 °C operating junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
Designed for automated SMT placement, SMBJ60AHE3/5B uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing. Its cathode band marking identifies polarity, and it is RoHS-compliant and halogen-free per Vishay's material categorization standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 60 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 66.7–73.7 V at 1 mA - Confirmed breakdown range ensures reliable turn-on during overvoltage events without premature leakage. |
| VC (Clamping Voltage) | 96.8 V at IPPM = 6.2 A - Measured clamping level limits stress on protected ICs during 10/1000 µs surge. |
| PPPM (Peak Pulse Power) | 600 W - Sustains high-energy transients per IEEE C62.35 standard without degradation under specified waveform. |
| IPPM (Peak Pulse Current) | 6.2 A - Maximum non-repetitive surge current capability with 10/1000 µs waveform, derated above 25 °C ambient. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance determines required PCB copper area (0.2" × 0.2") for thermal management. |
| Leakage (ID) | <1.0 µA at 60 V - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with molded compound meeting UL 94 V-0 flammability rating. Cathode identified by black band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance return plane; completes clamping loop during transient events. |
| Cathode | Reverse-biased terminal / Clamping node | Connected to protected line (e.g., 60 V rail); conducts when voltage exceeds VBR, shunting surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - supports under-hood and ADAS power rail protection. |
| 600 W peak pulse power | Handles high-energy lightning-induced surges (IEC 61000-4-5 Level 3/4) without failure when mounted on recommended 5.0 mm × 5.0 mm copper pads. |
| Fast response time (<1 ns) | Clamps transients before they reach vulnerable CMOS gate oxides or analog front-end circuitry, preventing latch-up or parametric shift. |
| Low clamping ratio (VC/VWM ≈ 1.61) | Minimizes overvoltage overshoot across protected devices - critical for 3.3 V/5 V logic and low-voltage microcontrollers. |
| MSL Level 1 moisture sensitivity | Enables standard reflow assembly without baking; compatible with high-volume SMT production using 260 °C peak profile. |
Applications
| Industrial Power Supply Protection | Telecom Line Card Surge Suppression |
|---|---|
Use Scenario: Protecting 48 V DC input rails in programmable logic controllers (PLCs) against inductive switching spikes and accidental AC mains coupling. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp positive transients only. Use Value: Limits voltage excursion to ≤96.8 V during 6.2 A surges, preserving upstream rectifier diodes and downstream DC-DC controllers rated for 100 V max input. |
Use Scenario: Shielding Ethernet PHY interface power pins (e.g., 3.3 V bias supply) from ESD and induced surges on adjacent data lines. IC Role / Device Role / Timing Role: Standoff-rated TVS on secondary-side bias rail, coordinated with common-mode chokes and gas discharge tubes. Use Value: Sub-1 µA leakage avoids loading low-current LDO outputs; fast clamping prevents PHY reset or packet corruption during ±8 kV contact ESD events. |
| Automotive Body Control Module (BCM) | Sensor Signal Line Protection |
Use Scenario: Safeguarding 12 V battery-fed MCU power inputs in BCMs exposed to load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Primary clamping device on main VBAT rail, positioned ahead of input filter capacitors and PMIC. Use Value: AEC-Q101 qualification ensures operation up to +150 °C junction temperature; 600 W rating absorbs 100 ms load dump energy without thermal runaway. |
Use Scenario: Guarding analog output lines (e.g., 0–5 V throttle position sensor) against cable discharge events and nearby relay switching noise. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ < 100 pF typical) placed directly at connector entry point. Use Value: 96.8 V clamping prevents op-amp saturation or ADC saturation; unidirectional configuration avoids interfering with sensor bias current paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60AHM3/5B | Halogen-free, RoHS-compliant, AEC-Q101 qualified - identical electrical specs but different material composition. | No functional difference; selected where halogen-free compliance is mandated (e.g., EU automotive Tier 1 requirements). | Choose SMBJ60AHM3/5B when halogen-free certification is contractually required; otherwise SMBJ60AHE3/5B is functionally interchangeable. |
| SMBJ60A-E3/5B | Commercial-grade (non-AEC-Q101), same package and electrical ratings; RoHS-compliant but not automotive-qualified. | Suitable for industrial or consumer applications where extended temperature reliability and automotive qualification are not needed. | Select SMBJ60A-E3/5B for cost-sensitive non-automotive designs; SMBJ60AHE3/5B adds qualification assurance for mission-critical systems. |
Compared with SMBJ60AHE3/5B, SMBJ60AHM3/5B provides identical surge performance with halogen-free materials, while SMBJ60A-E3/5B offers equal clamping and power handling without AEC-Q101 validation - enabling trade-offs between qualification scope, environmental compliance, and BOM cost.

FAQ
What is the clamping voltage of SMBJ60AHE3/5B at its rated peak pulse current?
The SMBJ60AHE3/5B has a maximum clamping voltage (VC) of 96.8 V when subjected to its rated peak pulse current of 6.2 A with a 10/1000 µs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ60AHE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBJ60AHE3/5B suitable for automotive applications?
Yes, SMBJ60AHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its part number. It undergoes rigorous stress testing including high-temperature reverse bias, temperature cycling, and surge endurance - making it appropriate for under-hood and chassis-mounted automotive systems such as body control modules and infotainment power rails. Its -55 °C to +150 °C operating junction temperature range supports these environments.
What package type does SMBJ60AHE3/5B use, and what are its key mechanical features?
SMBJ60AHE3/5B uses the SMB (DO-214AA) surface-mount package - a low-profile, rectangular case measuring 4.57 mm × 3.94 mm × 2.20 mm. Key mechanical features include UL 94 V-0 rated molding compound, matte tin-plated leads compliant with J-STD-002 solderability standards, and MSL Level 1 rating for lead-free reflow. The cathode is marked by a visible band on one end of the body.
How does the leakage current of SMBJ60AHE3/5B compare to similar TVS diodes?
SMBJ60AHE3/5B specifies a maximum reverse leakage current (ID) of 1.0 µA at its 60 V stand-off voltage (VWM), measured at 25 °C. This ultra-low leakage is consistent with Vishay's glass-passivated junction process and supports high-impedance signal lines and low-power sensor interfaces where even nanoamp-level leakage could affect accuracy or battery life. It matches or improves upon leakage performance of competing SMB-form factor TVS devices in the 60 V class.
Can SMBJ60AHE3/5B be used in bidirectional configurations?
No, SMBJ60AHE3/5B is a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" in its designation. It conducts only in reverse bias (cathode-to-anode) and must be oriented with its cathode toward the protected line. For bidirectional protection, Vishay offers the SMBJ60CA variant - which has symmetrical breakdown in both directions and no polarity marking. Using SMBJ60AHE3/5B in place of a bidirectional device would leave positive transients unprotected.
