Product details
Overview
SMBG60A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMBG (DO-215AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), clamping voltage of 96.8 V at 6.2 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG60A-E3/5B datasheet, SMBG60A-E3/5B pinout, SMBG60A-E3/5B application, or SMBG60A-E3/5B equivalent, key selection criteria include its unidirectional polarity, 60 V operating threshold, low clamping ratio (VC/VBR ≈ 1.34), 150 °C max junction temperature, and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, diverting surge current away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable avalanche characteristics and long-term reliability under repetitive surge stress.
The device is rated for 600 W peak pulse power with 10/1000 μs waveform at 0.01% duty cycle, supports 100 A non-repetitive forward surge (8.3 ms half-sine), and exhibits fast response time (<1 ns) due to its planar junction structure - critical for protecting high-speed signal lines and automotive ECUs against ESD and load-dump events.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A-E3/5B | Same VWM (60 V), identical SMB (DO-214AA) package footprint but 20% smaller body; 600 W rating; slightly higher VC (103 V @ 5.8 A). | Lower profile (2.4 mm vs. 2.6 mm height); better suited for space-constrained consumer PCBs; not AEC-Q101 qualified. | Select SMBJ60A-E3/5B only if automotive qualification is unnecessary and board height is constrained. |
| SMCJ60A-E3/5B | Same VWM and VBR range; larger SMC (DO-214AB) package; 1500 W peak power; 10.3 A IPPM; same AEC-Q101 qualification. | Higher surge capacity for heavy-duty industrial motor drives or railway power supplies; requires larger PCB area and thermal relief. | Choose SMCJ60A-E3/5B when system-level surge testing exceeds 600 W requirements or when extended thermal margin is needed. |
Compared with SMBJ60A-E3/5B and SMCJ60A-E3/5B, SMBG60A-E3/5B uniquely balances AEC-Q101 compliance, 600 W capability, and SMBG's optimized thermal resistance (RθJL = 20 °C/W) - making it the preferred choice for mid-tier automotive modules where footprint, reliability, and cost must all be tightly controlled.

FAQ
What is the clamping voltage of SMBG60A-E3/5B and how does it relate to system protection?
The SMBG60A-E3/5B has a maximum clamping voltage (VC) of 96.8 V at 6.2 A (10/1000 μs waveform). This value represents the highest voltage imposed on the protected circuit during a specified surge event. For a 48 V automotive system, this clamping level provides ~60% headroom above nominal rail voltage while staying well below typical 120 V absolute maximum ratings of downstream DC/DC converters and microcontrollers - ensuring reliable fault containment without overstressing protected components. The SMBG60A-E3/5B achieves this with a clamping ratio (VC/VBR) of approximately 1.34, indicating efficient avalanche conduction.
Is SMBG60A-E3/5B suitable for bidirectional transient protection?
No - SMBG60A-E3/5B is a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" in its part number. It conducts only when the cathode is positive relative to the anode, making it appropriate for DC power rail protection (e.g., 48 V battery inputs) where polarity is fixed. For bidirectional AC or differential signal line protection (e.g., CAN, USB, RS-485), a "CA"-suffixed variant such as SMBG60CA-E3/5B must be used. Using SMBG60A-E3/5B in bidirectional applications risks reverse breakdown failure during negative transients.
What does the "E3/5B" suffix indicate in SMBG60A-E3/5B?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance. The "/5B" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel - optimized for high-volume SMT placement. This differs from "/52", which specifies 7-inch reels with 750-unit quantities. Both variants share identical electrical and thermal specifications; only packaging and compliance grading differ.
How does SMBG60A-E3/5B perform under elevated ambient temperatures?
SMBG60A-E3/5B derates linearly above 25 °C ambient: its peak pulse power (PPPM) decreases by approximately 0.8% per °C rise, reaching ~480 W at +75 °C and ~360 W at +125 °C (per Fig. 2 in datasheet 88456). This behavior stems from junction-to-ambient thermal resistance (RθJA = 100 °C/W) and must be accounted for in thermally dense layouts. Designers should verify that actual board copper area (minimum 5.0 mm × 5.0 mm per pad) and airflow meet thermal requirements for worst-case surge repetition rates in the target application.
Can SMBG60A-E3/5B replace older P6KE60A or 1.5KE60A through-hole TVS diodes?
SMBG60A-E3/5B provides equivalent electrical protection (60 V VWM, 600 W PPPM) in a surface-mount SMBG package, but is not a direct mechanical replacement for axial-lead P6KE60A or DO-201AB 1.5KE60A. It requires PCB redesign to accommodate the SMBG footprint and thermal pad layout. However, it offers advantages including AEC-Q101 qualification, lower profile (2.6 mm height), improved automated assembly yield, and superior thermal resistance to lead (RθJL = 20 °C/W vs. ~30–40 °C/W for through-hole types). Migration is recommended for new designs targeting automotive or high-reliability industrial use.
