Product details
Overview
SMBJ60CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤96.8 V at 6.2 A peak surge current - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMBJ60CAHE3_A/I datasheet, SMBJ60CAHE3_A/I pinout, SMBJ60CAHE3_A/I application, or SMBJ60CAHE3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, clamping performance under standardized surge waveforms, and real-world use context for ESD/lightning transient suppression in bidirectional AC-coupled or floating circuits.
Technical Context
This device operates as a bidirectional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC lines, differential buses, and ungrounded signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 µA at 60 V), while the 100 °C/W junction-to-ambient thermal resistance reflects standard PCB mounting on 5.0 mm × 5.0 mm copper pads.
The SMBJ60CAHE3_A/I meets J-STD-020 MSL Level 1 (260 °C peak reflow), supports 150 °C maximum junction temperature, and is qualified to AEC-Q101 for automotive applications - confirmed by the "HE3" suffix and documented in Vishay's ordering matrix and revision notes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC RMS working range. |
| VBR min/max | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown threshold range; ensures reliable turn-on during transients exceeding VWM. |
| VC @ IPPM | ≤96.8 V at 6.2 A - Clamped voltage under 10/1000 µs surge; determines maximum stress imposed on downstream circuitry. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs waveform; enables robust protection against lightning-induced surges (IEC 61000-4-5). |
| ID @ VWM | ≤1.0 µA - Reverse leakage at rated standoff; critical for low-power sensor biasing and battery-backed systems. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| RθJA | 100 °C/W - Thermal resistance junction-to-ambient on standard pad layout; informs derating requirements above 25 °C ambient. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; symmetrical terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative half-cycle) | Conducts during negative voltage excursions; forms one side of symmetrical clamping path. |
| Cathode | Transient current entry (positive half-cycle) | Conducts during positive voltage excursions; completes bidirectional clamping function with Anode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines, RS-485, CAN FD, and floating sensor bridges without external polarity management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CAHM3_A/I | Halogen-free, RoHS-compliant variant with identical electrical specs and AEC-Q101 qualification. | No functional difference; selected where halogen-free material compliance is mandated (e.g., EU medical or public infrastructure projects). | Choose SMBJ60CAHM3_A/I when halogen-free composition is contractually required; otherwise SMBJ60CAHE3_A/I offers same performance at standard cost. |
| SMAJ60CAHE3_A/I | Lower 400 W PPPM rating, same VWM/VBR, SMA (DO-214AC) package - smaller footprint but higher RθJA (140 °C/W). | Suitable only for lower-energy transients or space-constrained designs where thermal margin allows reduced power handling. | Select SMBJ60CAHE3_A/I over SMAJ60CAHE3_A/I when full 600 W surge immunity is needed or board layout permits SMB size for better thermal dissipation. |
Compared with SMBJ60CAHM3_A/I, the SMBJ60CAHE3_A/I trades halogen-free content for broader supply availability; versus SMAJ60CAHE3_A/I, it delivers +50 % peak pulse power and −29 % thermal resistance - directly improving surge survivability and long-term reliability in thermally demanding automotive and industrial deployments.

FAQ
What does the "CA" suffix indicate in SMBJ60CAHE3_A/I?
The "CA" suffix denotes a bidirectional configuration - meaning SMBJ60CAHE3_A/I provides symmetrical clamping for both positive and negative voltage transients without polarity dependence. This distinguishes it from unidirectional variants (e.g., SMBJ60AHE3_A/I) and makes SMBJ60CAHE3_A/I ideal for AC-coupled lines, differential buses like RS-485, and floating sensor interfaces where voltage polarity is undefined or alternating.
Is SMBJ60CAHE3_A/I qualified for automotive applications?
Yes, SMBJ60CAHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay's official ordering documentation. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and surge endurance - validating SMBJ60CAHE3_A/I for under-hood and chassis-mounted automotive electronics such as body control modules, ADAS sensor hubs, and infotainment power supplies.
What is the maximum clamping voltage for SMBJ60CAHE3_A/I under surge conditions?
The maximum clamping voltage (VC) for SMBJ60CAHE3_A/I is 96.8 V at a peak pulse current (IPPM) of 6.2 A, measured with a 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during standardized surge events, ensuring downstream ICs rated for ≤100 V absolute maximum survive IEC 61000-4-5 Level 4 (4 kV) transients when SMBJ60CAHE3_A/I is correctly applied.
How does the SMB (DO-214AA) package of SMBJ60CAHE3_A/I compare thermally to SMA (DO-214AC)?
The SMB package used in SMBJ60CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W on standard 5.0 mm × 5.0 mm copper pads, versus ~140 °C/W for the smaller SMA package. This 29 % lower thermal resistance allows SMBJ60CAHE3_A/I to sustain higher average power dissipation and recover faster between surge events - a key advantage in high-duty-cycle industrial environments where SMBJ60CAHE3_A/I outperforms SMAJ60CAHE3_A/I in thermal margin and reliability.
Can SMBJ60CAHE3_A/I be used in place of unidirectional TVS diodes?
No - SMBJ60CAHE3_A/I is strictly bidirectional and lacks anode/cathode polarity marking; substituting it for a unidirectional TVS (e.g., SMBJ60AHE3_A/I) would compromise protection on DC-biased lines where only one polarity requires clamping. SMBJ60CAHE3_A/I must be used only in applications requiring symmetrical clamping, such as AC signal paths, transformer-isolated interfaces, or floating grounds - never as a drop-in replacement for unidirectional devices without circuit redesign.
